Abstract

The invention relates to a preparation method of a polyaniline/P(MMA-BA-HEA) conductive composite material, which takes butyl acrylate, methyl methacrylate, hydroxyethyl acrylate and aniline as raw materials, and comprises the following steps: first, preparing a P(MMA-BA-HEA) emulsion by taking fatty alcohol-polyoxyethylene ether, sodium dodecyl benzene sulfonate and n-amyl alcohol as emulsifying agents and taking azo-diisopropyl-imidazoline as an initiator; and then obtaining the polyaniline (PANI)/P (MMA-BA-HEA) conductive composite material by the in situ polymerization of the aniline in the copolymer emulsion. The polyaniline conductive composite material of the invention has good conductivity and processability, the highest conductivity of the composite material is 1.472S. cm<-1>, the composite material PANI/P (MMA-BA-HEA) has good solubility in organic solvents, such as cyclohexanone, N-methylpyrrolidone and dimethyl sulfoxide, and the problems of processing difficulty and application of the polyaniline conductive material are solved.

Description

technical field [0001] The invention relates to a preparation method of polyaniline / P(MMA-BA-HEA) conductive composite material. Background technique [0002] Polyaniline is a new type of polymer conductive material, which has the advantages of low raw material price, simple synthesis, high conductivity, good oxidation resistance, and good environmental stability, and has become a research hotspot. So far, it has been applied in nanomaterials, secondary batteries, antistatic and electromagnetic shielding materials, anticorrosion materials, supercapacitors, selectively permeable membranes, sensors, molecular wires and molecular devices, artificial muscles, etc. [0003] However, due to the infusibility and insolubility of polyaniline, its comprehensive mechanical properties are poor, and it cannot be directly molded by traditional methods, which limits its application to a large extent. At present, the processability of polyaniline is improved by doping, preparing polyanilin...
