Polymer is modified.Copolymerization can integrate the advantage of several links, and then it is more preferably new to prepare chemical property
Type conducting polymer.Xu Hui etc. uses CV methods electro-deposition polyaniline/polypyrrole laminated film on stainless steel substrate, finds multiple
Close film has more preferable decay resistance than pure one-component film.At present, conjunction of the domestic and foreign scholars for conductive homopolymer
Research into, properity is more but actually rare to the research of copoly type conducting polymer.The present invention is prepared for sulfo group water
The aniline of poplar acid doping/pyrroles's conductive copolymer（PANI/PY-SSA）, and using it as functional component, using epoxy resin as film forming
Material, coating is prepared for by mechanical blending, has inquired into anti-corrosion capability of the conductive copolymer film to low-alloy steel base material；
Polyaniline and polypyrrole are as most representational two representatives of conducting polymer family, due to its unique anticorrosion machine
There is wide application prospect in anticorrosion field in system and good anticorrosion ability, this two classes conducting polymer, copolymerization changes
Property be to improve its machinability and decay resistance to provide new solution path.Inorganic nanometer powder material polymerize with some
The incomparable physicochemical properties of thing, the compound both it has decay resistance more more preferable than one-component.In recent years,
Decay resistance research of the domestic and foreign scholars to conductive homopolymer composite is relatively broad, but to conductive copolymer and its is combined
The report of material is but more rare.Therefore, in order to prepare the more preferable composite of decay resistance, we are prepared for conductive common
Polymers and a series of conductive copolymer/inorganic composites.Want to prepare the more conductive homopolymer of decay resistance and conduction
The more preferable conductive copolymer of copolymer/inorganic compounding powder, plays more preferable metal coating effect；
Low-carbon steel material due to have the advantages that easy processing forge, easily welding, Cutting free, be often processed to all kinds of big machineries
Parts, be widely used in fields such as Aero-Space, automobile, ship and buildings.But itself easily occur intercrystalline attack, point to invade
The corrosion behaviors, the serious application and service life that have impact on low-carbon steel material such as erosion, erosion cracking.With polyaniline and poly-
Pyrroles is led due to its unique anticorrosion mechanism and excellent Corrosion Protection for the conductive polymer sub-family of representative in anticorrosion
Domain causes more and more extensive concern.In order that the outstanding chemical property of conducting polymer and inorganic nano-particle are special
Physical and chemical performance brings out the best in each other, and people often take inorganic nano-particle with the mode that conducting polymer is mutually combined to realize this mesh
's.Therefore, the functional paint using conducting polymer/inorganic composite materials as conductive filler turns into the research of anticorrosion field newly
Focus.At present, synthesis, properity research of the domestic and foreign scholars to conductive homopolymer and its inorganic composite materials are more, but lead
The research and discussion of electric copolymer/inorganic composite but rarely have report.
