Description

A kind of macromolecule composite functional fiber containing partial reduction Graphene and preparation method thereof
Technical field
The invention belongs to technical field of polymer materials, it is related to a kind of macromolecule complex function containing partial reduction Graphene Fiber and preparation method thereof.
Background technology
Functional fibre refers to the tencel with one or more specific functions, such as conductive fiber, fire resistance fibre, antibacterial Fiber etc..Functional fibre has the characteristics that high technology content, high added value, the high market demand., due to tool taking conductive fiber as a example There are the characteristics such as antistatic, electromagnetic wave absorption, be the high added values such as antistatic explosion-proof clothing, dust-free sterile clothes, high-grade clothing and home textile The required raw material of product, is applied to Aero-Space, defence and military, petrochemical industry, mining, microelectronics, biological medicine, Precision Machining, spinning The various fields such as woven garment, wide market.
The preparation of functional fibre is general to be passed through to add micron or nanoscale functional stuffing in macromolecule matrix, including charcoal Black, metal and metal oxide powder, CNT or carbon nano-fiber etc., are then obtained through spinning technique.Required for realizing Function as conductive, the content of filler must be over and could form conductive network during a certain particular value, and this value is commonly known as and " exceedes Ooze threshold value ".The percolation threshold of conventional filler (as white carbon black and metal dust) is higher, often beyond 20, thus brings spinnability Be deteriorated, the problems such as fibre strength declines, feel is stiff, fiber number and density increase.
Additionally, the single function of conventional filler.For example: white carbon black primarily serves electric action;Magnesium hydroxide plays fire retardation; The metals such as silver, copper, zinc (or its ion) primarily serve antibacterial action, etc..For realizing complex function, generally require to add simultaneously Multiple fillers, when its content all reaches sufficiently high, produce conductive, fire-retardant, antibacterial and other effects respectively.This certainly will increase further Content in macromolecule matrix for the filler, makes the problem of above-mentioned spinnability and fibre property aspect more prominent.Therefore, have concurrently many Although the macromolecule composite functional fiber prospect of kind of function is tempting, its research and development difficult point is still very big.
As a class nano material of latest development after CNT, Graphene has more excellent electric conductivity and pole High radius-thickness ratio and specific surface area.It is reported that, the Graphene as little as 0.1~3.8vol of the percolation threshold in various macromolecules, Significant electric conductivity lifting can be obtained under extremely low addition.The Chinese invention patent Shen of Publication No. cn103710790a Please be functional stuffing using Graphene, antistatic, antibacterial, Graphene increasing are prepared by in-situ polymerization and composite spinning technology Strong bi-component composite polyester fiber, wherein component a are the polyester of not graphene-containing, component b be containing percentage by weight 0.3~ The polyester of 3.0 Graphene.The Chinese invention patent application of Publication No. cn103215689a discloses a kind of Graphene and changes Property nylon 6 fiber preparation method, Graphene is carried out after carboxylated, chloride and amination process, anti-by in-situ polymerization Graphene modified nylon 6 melt should be obtained, then obtain Graphene reinforced nylon 6 fiber through melt-spinning technology.
It can be seen that, macromolecule composite functional fiber is prepared for functional stuffing using Graphene and is taken seriously.Using Graphene Relatively low percolation threshold is it is possible to realize enhancing, the characteristic such as conduction, antibacterial under relatively low filer content.But the receiving of Graphene Rice lamellar structure and its surface lack active group and also lead to its piece inter-layer bonding force high, directly mix not easy-peel with macromolecule From the aggregate of formation micron level, has seriously undermined the advantages such as its specific area, high conductivity and low percolation threshold on the contrary.
