Conductive polymer material refers to that conductive or conductive after the chemical doping one kind of this body structure of macromolecule is high
Molecular material；And conductive polymeric composite refers to conductive high molecular material after physical modification, generally
Using certain polymer as matrix, various antistatic agents, inorganic conductive filler or hydrophilic polymer is added and is combined.
And conductive polymeric composite, using polymer as parent, filling inorganic conductive filler mixture is formed.It is inorganic to lead
Electric filler can be divided into carbon, metal, conductor oxidate and their compound by the type of substance, and spatially structure point can be
Threadiness, sheet, granular and with special three-dimensional structure shape, and dark and light-colored antistatic material can be divided by color
It was both conductive, and simple and easy, had been widely used.But currently, multiple by the electric conductivity of matrix of polymer
For condensation material, the research of carbon system filler is more, and studies metal system filler then less.Metal system filler mainly has metal fine
Dimension, metal powder, metal alloy and other novel compound filling filled composite type conductive polymer materials, wherein metallic fiber compared with
For other metal packings, there are biggish draw ratio and contact area, therefore, in the case where identical loading, metal is fine
Dimension easily forms conductive network, and conductivity is also higher, using also more extensive.Fiber loading to the affecting laws of conductivity with
Carbon black-filled situation is similar, and one timing of fiber volume loading, and draw ratio is bigger, and electric conductivity is better.In fiber and matrix
Recombination process injects appropriate to the occasion reductions screw speed and back pressure, raising machine barrel and mold temperature to avoid fibrous fracture, sometimes for
The uniformity for improving dispersion, also needs that processing aid appropriate is added.In the research and application of metallic fiber filler, improve its
Dispersibility and additive amount in plastics are the main direction of development.
At present both at home and abroad the metal packing for plastics, especially metallic fiber surface side filler achieved centainly at
Effect.Wherein Qiao Jinliang et al. has invented a kind of preparation method of ultrafine metal fibers and its ultrafine metal fibers (China of preparation
Application number of invention patent 201310512079.1), preparation method is by fusing point not less than fluoropolymer resin fusing point or softening temperature

To stretching, the polymer/metal composite fibre containing ultrafine metal fibers is obtained.In addition, Xiong Ruibin et al. has invented a kind of gold
Belong to the preparation process (Chinese invention patent application number 201310738988.7) of fiber, comprising the following steps: (1) using continuous electricity
Solution coats auxiliary material on the surface of more one metal wire materials；(2) metal wire material after more cladding auxiliary materials is encapsulated into
Auxiliary tubing in form composite metal, assist the weight percent of tubing form are as follows: boron or rare earth, carbon, surplus be iron with
Inevitable impurity；(3) composite metal is carried out to multi pass drawing, annealing on wire drawing machine, obtains metal composite
Line；(4) using metal composite wire as anode, the auxiliary material of electrolysis removal cladding and the auxiliary tube of encapsulation are carried out in acid solution
Material is cleaned using multiple deionized water, and last sufficiently drying obtains metallic fiber.
As it can be seen that group easily occurs for the metallic fiber filler of plastics and high molecular polymer poor compatibility in the prior art
Poly- phenomenon, dispersion is uneven, and then causes loading small, and thermoplasticity is poor, and modified effect is undesirable, and electric conductivity is bad, and traditional
Improve metallic fiber dispersed method in the polymer by the way that dispersing agent or other auxiliary agents are added, operating process is complicated,
Higher cost, and dispersion is still without significantly improving.
