Embodiment Construction

[0020] Preparation of reaction solution: 0.01M-1M ferric chloride (or ammonium persulfate, chloroauric acid and other oxidative initiators), hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, perchloric acid can be used, the concentration is 0.1M-5M, The concentration of aniline monomer is 0.01M-1M. After the solution is evenly mixed, transfer the reaction solution to a polytetrafluoroethylene-lined autoclave, put it into an oven to control the reaction temperature at 100-250°C, or use high-temperature heat transfer oil or direct electric heating to control the reaction temperature. Time 1-30 hours. The reaction temperature is at multiple temperature control points (100, 150, 180, 200, 250°C) at 100-250°C, and at multiple points (1, 4, 5, 8, 10, 30°C) between 1-30 hours of reaction time hours) to control, the result has no significant difference, including different reaction solution systems, and its difference mainly lies in the productive rate of product.

Abstract

This invention relates to a controllable synthesized method of new style polyaniline self-assembly nanostructure. The method is that poly reaction is happened at 100~2500C in autoclave, dopant is protonic acid of oxidative polymerization reaction, then polyaniline flake structure is got and order tactic polyaniline nanometer bar (fiber) array on its surface. The structure has great photism. The array can be used to electromagnetic wave shield materials, antistatic materials, big content capacitor material, triode, sensor material, gas separation material and high efficiency photism.

Description

1. Technical field: [0001] The invention relates to a controllable synthesis method and application of a novel polyaniline self-assembled nanostructure. 2. Background technology: [0002] Polyaniline is an important conductive polymer (plastic), which has the advantages of stable chemical properties and high conductivity [1] A.G.MacDiarmid, Synthetic metals: A Novel role for organicpolymers, Angew.Chem.Int.Ed.2001, 40, 2581-2590. By controlling different doping levels, the conductivity of polyaniline can be transformed from insulator-semiconductor-metal conductor. In recent years, polyaniline and nanostructured polyaniline have been widely used in solar cells and electromagnetic wave shielding materials [2] Wan Meixiang, Li Junchao, Li Suzhen, A conductive high polymer microwave absorber and its preparation method, Chinese Patent Publication No. 1110786, Bulletin No. 1040043. Antistatic materials [3] E. Rodriguez J. W. Lindsay, Antistatic fiber and its preparation method, ...
