Background
The beauty and medical industry is born in the 90 s of the 20 th century and is based on the expansion of the fields of medicine, optics, electricity, chemistry and the like. Cosmetic instruments have also undergone a further update. The beauty instrument is a machine for regulating and improving the body and the face according to the physiological functions of a human body, and has various functions such as whitening, skin tendering, freckle removal, wrinkle removal, hair removal, weight reduction and the like, and has the functions of an ultrasonic face cleaner, a micro-current face tightening instrument, a blue light acne removal beauty bar, a face thinning electric beauty instrument, an ion leading-in instrument, a face steaming instrument, a hair removal instrument, a nano water supplementing instrument, an ultrasonic color light toxin expelling beauty instrument, a PMD microcrystalline skin grinder, an ion tooth whitening instrument, a laser hair removal instrument, a photon skin tendering instrument and the like. The volume of the device is gradually changed from huge instruments to medium-sized, medium-sized and small-sized instruments, and the small-sized and micro-sized instruments are gradually changed into a trend nowadays. The functions of the hair remover are gradually developed from single depilation, whitening and the like to one machine with multiple functions, the functions tend to be more and more perfect, the development of scientific technology and the application of the hair remover on a cosmetic instrument lead the functions of the hair remover to be more and more diversified and finer. However, these instruments have the disadvantages of high price, large volume, inapplicability to household and personal consumption, etc.
The microcurrent beauty instrument in the prior art is a beauty instrument which acts on a human body through computer microwaves, supplements bioelectricity of the human body, activates cells and recovers skin elasticity, thereby achieving the effects of solving some skin problems and delaying skin aging. Such instruments are commonly used in many care sessions in beauty parlors, such as tightening skin, removing wrinkles, lightening dark circles, etc., with the following cosmetic functions: 1. enhancing cell activity, promoting muscle movement, and recovering skin elasticity; 2. accelerating blood circulation of the capillary, enhancing cell permeability, and effectively supplying nutrients to muscle tissues and skin; 3. the electric ions generated by the micro-current can deeply permeate the skin, and supplement the moisture of the skin to restore and moisten, smooth and tender; 4. the microwave current makes the electric stimulation go deep into subcutaneous tissue to muscle, and helps to repair skin elastic fiber and colloid layer tissue, thereby stretching and weakening wrinkles.
CN105611965a discloses a portable iontophoresis system using a mask, which is to provide an iontophoresis device having two electrodes, one electrode is in contact with the skin of a human body, and the other electrode is connected to one corner of a general mask using forceps, so as to transfer micro-current to the mask; however, the common mask cannot conduct electricity, so that an effective micro-current effect cannot be realized on the face, and the skin beautifying effect is achieved; meanwhile, common metal is in contact with the mask liquid in an electrified state, so that ionic reaction is very easy to occur, and the introduction effect cannot be realized.
Disclosure of Invention
In order to solve the technical defects, the invention provides a novel leading-in type beauty mask which is prepared from a biological cellulose composite film with conductive performance.
Biocellulose (biocellose), also known as bacterial cellulose (Bacterial cellulose, BC), is cellulose synthesized by certain microorganisms of the genus acetobacter, agrobacterium, rhizobium, and the like. Unlike plant cellulose, biological cellulose is not a structural component of bacterial cell walls, but a product secreted by bacteria to the outside of cells, is in an independent filiform fiber form, is cellulose formed by the condensation polymerization of pure glucose, has extremely high cellulose content, is not doped with lignin, hemicellulose and other polysaccharide impurities, and has a very different microfibril mode from plant cellulose. Common bacteria of the biological cellulose producing strain are acetobacter xylinum, acetobacter xylosoxidans and the like. The ultra-high-purity cellulose structure of the biological cellulose gel has gel characteristics and appearance, and the biological cellulose gel has high crystallinity (up to 95%) and high polymerization degree (DP value 2000-8000); has ultra-fine net structure and tensile strength, and also has excellent water holding capacity, high biocompatibility and degradability. Currently, the method is widely applied to various fields such as foods, medicines and the like.
The invention adopts the biological cellulose membrane as a base material, and the biological cellulose membrane is coated with conductive polymer to ensure that the biological cellulose membrane has conductive performance, and can realize effective micro-current effect at the using part of the mask after being connected with a micro-current generator or a pulse generator, thereby achieving the effects of skin care and beauty. The diameter of the biological cellulose fiber is in the nanometer range, the formed pore diameter is also in the nanometer range, and the porous structure and a certain nanoscale pore diameter distribution can be used as templates to control and synthesize the nanometer material or the nanometer structure with the expected specific shape and size, thereby obtaining new different functional materials. The biological cellulose is used as a template, and the nano-scale composite material with the three-dimensional network structure can be synthesized through synthesis routes such as in-situ synthesis and the like by utilizing the nano-scale superfine network structure and a large number of active hydroxyl groups on the surface of the biological cellulose. The invention preferably adopts an in-situ chemical oxidation polymerization method to prepare the biological cellulose film coated with the conductive polymer, wherein the conductive polymer comprises polyacetylene, polypyrrole, polythiophene, poly-p-styrene, polyaniline and the like.
Furthermore, the invention also provides a more excellent technical scheme, namely, when the biological cellulose film coated with the conductive polymer is prepared, an alkali treatment step is added before the in-situ chemical oxidation polymerization step is carried out. The alkali treatment step is preferably to soak the biological cellulose membrane in 2-10wt% sodium hydroxide solution or potassium hydroxide solution at 80-100deg.C for 1-5 hr. The invention innovatively discovers that the biological cellulose can form a more complete core-shell structure with conductive polymers such as polypyrrole after alkali treatment. The method is characterized in that after the biological cellulose is subjected to alkali treatment, more surface active hydroxyl groups are released, polypyrrole forms a more perfect continuous coating structure under the guidance of the active hydroxyl groups in the polymerization process, so that the agglomeration phenomenon is greatly reduced, and the surface smoothness of the fiber is also greatly improved. By detection, the conductivity of the biological cellulose composite membrane before alkali treatment is more than 0.5S/cm, and generally only 0.5-0.7S/cm. The conductivity of the biological cellulose composite membrane prepared after alkali treatment is generally more than 1.5S/cm and can reach 2.5S/cm at most.
The preparation method of the biological cellulose composite membrane with the conductive performance provided by the invention comprises the following steps:
(1) Washing the biological cellulose wet film obtained by fermentation with distilled water or deionized water, and mechanically compressing to remove free water in the biological cellulose film until the water content is below 30-50wt%;
(2) Immersing the treated biological cellulose membrane in a solution containing 0.2-1.0 mol/L pyrrole monomer, magnetically stirring for 2-3 hours, and fully adsorbing the pyrrole monomer by the biological cellulose membrane after the action;
(3) Dropwise adding a proper amount of oxidant solution (the oxidant can be ferric trichloride, ammonium persulfate and the like, and the molar ratio of the oxidant to the pyrrole is 1:2-1:3), reacting at room temperature, polymerizing the pyrrole on the surface of the biological cellulose membrane, and uniformly coating the surface of the biological cellulose nanofiber;
(4) And (3) sequentially cleaning the product obtained in the step (3) by using 75wt% ethanol and distilled water, and then freeze-drying for about 24 hours to obtain the biological cellulose composite membrane with the conductive performance.
The method can be used for coating polypyrrole, and is also suitable for in-situ chemical oxidative polymerization coating of conductive polymers such as polyacetylene, polythiophene, poly-p-styrene, polyaniline and the like. Meanwhile, in order to further improve the conductivity, the above method preferably further comprises an alkali treatment step between the steps (1) and (2), such as immersing the biological cellulose membrane in an alkali solution by using a sodium hydroxide solution or potassium hydroxide solution with a concentration (2-10 wt%, preferably 5 wt%) and placing the biological cellulose membrane in a boiling water bath with a temperature of about 100 ℃ for 1-2 hours, cooling, and washing with deionized water until the biological cellulose membrane is neutral for standby.
Still preferably, the present invention provides an introducing type cosmetic device, comprising an introducing type cosmetic mask, and further comprising a micro-current generator or pulse generator electrically connected to the mask, a mask storage box, a cosmetic liquid, a power supply and a power supply connection line. The leading-in type beauty mask is made into a shape which is attached to a human face or other areas needing beauty care and is electrically connected with a micro-current generator or a pulse generator; the micro-current generator or pulse generator is connected to a power source (with a control switch) through a power source connection line, and the power source connection line can be made into separate type. When the facial mask is not used at ordinary times, the facial mask is placed in a facial mask storage box, when the facial mask is used, the facial mask is soaked in the beauty treatment liquid firstly, and then is applied to the face of a user or other areas needing beauty treatment after being fully soaked for a period of time, then the power supply of a micro-current generator or a pulse generator is connected, and low-frequency micro-current or ultrasonic waves of about 50 Hz are generated, so that the low-frequency micro-current or the ultrasonic waves act on the face of the user or other areas needing beauty treatment, and the low-frequency micro-current can promote skin metabolism, restore elasticity, exercise muscles and promote blood circulation; the ultrasonic wave can promote metabolism, accelerate blood and lymph circulation, improve the ischemia and hypoxia state of cells, improve tissue nutrition, improve regeneration function and the like; simultaneously, the beauty components in the beauty liquid can be guided into the skin surface layer to achieve better absorption effect.
