Under premise, reduce the addition (i.e. reducing conduction percolation threshold) of electrically conductive polyaniline, acquisition has good mechanical property and adds
Work performance, and electrical property not by processing and forming externally magnetic field effect or to affect minimum composite be study hotspot in recent years.Mesh
A front trend is to use multi-phase polymer co-mixing system to reduce the content of conductive agent in conduction high polymer, and high polymer is blended
Be separated and the conductive additive of thing are optionally distributed in a certain phase, it is possible to obtain in the case of conductive agent consumption is relatively low
The composite of high conductivity, on the other hand can provide reasonable processing characteristics, and effectively reduce due to filler
The impact that the mechanical performance that content increases and causes declines.Separated and the control conductive agent of superpolymer blend is in system
Distribution and arrangement mode are the important channels of the conduction composite high-molecular material obtaining high-performance, low cost, are also conductive polymers
The development trend of sub-composite.
