Problems solved by technology

However, due to the insolubility and infusibility of conductive polyaniline, as well as the disadvantages of poor mechanical properties, its wide application in technology is limited.
At present, it is only used in a few fields such as antistatic technology, electromagnetic shielding technology and secondary batteries.

Abstract

The invention relates to the current conducting ployaniline composite membrane having the framework of the lotus leaf genus. It is the cancellated film composed by the nm fibre with microsphere and has the tuber on the surface of the fibre and the microsphere. The producing process of the composite includes the below steps: the eigenstate polyaniline is dissolved into the solvent; the insoluble substance is rejected, the adulterating acid is added; then, the polystyrene is added; the current conducting polyaniline mixed liquor is gained; finally, the petrified urrent conducting ployaniline composite membrance is gained one the receiving system using the electrostatic spinning technique. The composite membrane is indicative of the contact angle of 160 degree and the roll angle of below 5 degree to the pure water, the acid and the alkaline solution in the range of the entirely PH value and express the sky high ability of self purging; at the same time, the conductivity of the conducting macromolecule composite membrane don't change with the acid and alkaline solution. The conducting composite membrane can be used for producing the resisting electromagnetic shielding material, the antistatic stuff, the anticorrosion stuff, the anti fouling stuff of the shipping and the airplane, the latent stuff, the liquid transmission without the loss and the micro-flow stuff.

Description

technical field [0001] The invention relates to the field of functional materials, in particular to a superhydrophobic, superhydrophobic acid and alkali solution conductive polyaniline composite film with high contact angle and low rolling angle, and a large-scale electrospinning film using electrospinning technology. The invention discloses a preparation method for producing the conductive polyaniline / polystyrene composite film, and its application. Background technique [0002] Conductive polymer materials have attracted great attention from all over the world because of their special functions, especially intrinsic conjugated conductive polymers, which can be widely used in chemical power supplies, electromagnetic shielding, antistatic, information storage and processing, and electrochromic materials. etc. Among them, polyaniline is considered to be a kind of high polymer with the most practical application prospect because of its readily available raw materials, simple ...
