The present invention is related to CNT composite construction, especially a kind of to have high moisturizing
Property and high bactericidal properties tool Nano particles of silicon dioxide and Nano silver grain nano-sized carbon
Pipe composite construction.
Background technology
CNT (Carbon Nanotube, abridge CNT) is a kind of tubulose
Carbon molecules, each carbon atom takes sp on the CNT2Blend together, and between each other
With carbon-to-carbon σ bond altogether, and formed by hexagonal groups into alveolate texture,
And as the skeleton of the CNT.Wherein on each carbon atom of the CNT
A pair of the p electronics blended together are had neither part nor lot in be formed between each other across whole CNT
Conjugated pi electron cloud.CNT is different according to the number of plies of pipe, can be divided into single wall
CNT and modification multiple-wall carbon nanotube.The radial direction of CNT is quite thin,
Only nanoscale, and it is axially then and tens of arrives hundreds of microns.
The composite wood of many excellent performances can be produced using the property of CNT
Material., can also biologically CNT can produce cytothesis the effect of
Infrared ray is absorbed, therefore has at a relatively high potential in thermotherapy.Therefore present invention invention
People wishes to apply CNT on biologic medical, especially using wound sterilization material as
That applies is preferential, but such raw doctor's material, must often have effect moisturizing and sterilization
Function.Moisturizing is to be maintained water adsorption by means of the amido modified on silicon material,
Sterilization then can reach effect by Nano silver grain.The CNT not modified is in itself
And available moisture and itself can not often have bactericidal property, furthermore commercially available silver kills
Bacterium material is more is attached in a manner of coating on its material, can not effectively consolidate and in right amount
It is incorporated on CNT, the phenomenon to come off is also more obvious.
Therefore present invention hope proposes one kind using CNT as substrate, with reference to the high guarantor of tool
Moist silicon material and the CNT composite construction of silver nanoparticle of bactericidal properties, with solution
The certainly technical defect of current industrial.
The content of the invention
So the purpose of the present invention is to solve the problems, such as in above-mentioned prior art, this hair

It refer to shown in Fig. 1 to Fig. 4, show the tool humectant and height of the present invention
The tool Nano particles of silicon dioxide of bactericidal properties and the CNT of Nano silver grain are compound
Structure, include following elements：
One modification multiple-wall carbon nanotube (MWCNT) 10, the modification multiple-wall carbon nanotube
10 length is about at 35 μm to 60 μm.And the benzene of the modification multiple-wall carbon nanotube 10
Ring it is carbon-based on be combined with COOH, OH, SO functional group.Its mode is by original
First longer multiple-wall carbon nanotube (length is about at 300 μm), by H2SO4And
HNO3Mixed liquor immersion after so that the HNO3Aoxidize longer more wall nanometers
Carbon pipe, and the H2SO4Its dehydration property is then applied, hence in so that the longer Duo Bina
Rice carbon pipe produces above-mentioned functional group.And this is longer more in the process of oxidation
The surface of wall carbon nanotube generates newly because chemical reaction causes its structure defect occur
Functional group, therefore produce the change and fracture of chemical bond, and it is longer to influence this
The structure of multiple-wall carbon nanotube so that entire length shortens, and it is more to form the modification
Wall carbon nanotube 10, the wherein COOH, the functional group such as OH, SO can make the modification
The surface of multiple-wall carbon nanotube 10 carries negative electrical charge, hence in so that entirely modifying more walls
CNT 10 turns into the nanostructured of surface tool negative electrical charge.These officials can be utilized
Electronegative surface charge caused by energy base, and the particle opposite with remaining charge polarity
The effect mutually adsorbed is produced, to increase the absorption of the modification multiple-wall carbon nanotube 10
Ability.
The adhesion layer 20 of one tool polarity, is attached to acidic group and changes using its surface charge
On the modification multiple-wall carbon nanotube 10 of matter, the adhesion layer 20 mainly includes：

The absorption of son 22 is in the SiO2Around@EDAS nanoparticles 21, and it is electrically attracting
Effect by the SiO2@EDAS nano-particles 21 are attached to the more wall nano-sized carbons of the modification
On pipe 10 so that the Ag@Citrate nms molecule 22 changes also with this is attached to
On matter multiple-wall carbon nanotube 10.If do not use the SiO2@EDAS nano-particles
21, then Ag@Citrate nms molecule 22 can not possibly be adsorbed onto the more walls of the modification and received
On rice carbon pipe 10.So due on the modification multiple-wall carbon nanotube 10 in the present invention
Include the SiO simultaneously2@EDAS nanoparticles 21 and the Ag@Citrate nanometers point
Son 22, so also having the effect of moisturizing and sterilization simultaneously.
The effect of being shown in Fig. 3 and Fig. 4 according to measured by experiment.Shown in Fig. 3
SiO2Hydrated granular radius, wherein the average for showing the particle diameter is 126nm,
In Fig. 4, then SiO is shown2@EDAS particle diameters of hydrated granular after hydration are about
400nm, the SiO synthesized by the present invention2Size is about 120~160nm or so, modification
The SiO that upper EDAS is generated2@EDAS granular size is about 110~200nm left sides
It is right, it is seen that SiO2And reaction bad to the adsorption capacity of hydrone is in its less water
Conjunction radius, and SiO2After being hydrated, particle diameter is about 400nm to@EDAS, it is seen that
The hydration half that its peripheral functional group is easily significantly increased at it with Water Molecular Adsorption and reaction
Footpath, so the present invention effectively adsorbed water molecule and can improve moisture retention really.Separately
Outer inventor, which also tests, clearly shows the upper and lower surface of the MWCNT really
Negative potential is presented.
In summary, the design of consideration of hommization of the present invention, actual need are quite met
Ask.It specifically improves existing missing, substantially has compared to prior art breakthrough
Progress advantage, there is the enhancement of effect really, and non-be easy to reach.The present invention
Domestic document and in the market with foreign countries is not disclosed or be exposed in, has met patent
Law regulation.
Above-listed detailed description is to be directed to a possible embodiments of the invention specifically
It is bright, only the embodiment and be not used to limitation the present invention the scope of the claims, it is all without departing from
The equivalence enforcement or change that skill spirit of the present invention is made, are intended to be limited solely by the present invention
