Embodiment 1

[0016] (1) Put 1 gram of aniline monomer, 0-50ml of deionized water, and 0-50ml of camphorsulfonic acid into a three-necked flask, stir evenly, and place in an electrolytic cell for electrochemical polymerization at a temperature of -10°C-80°C °C, the polymerization reaction time is 1-24 hours, after the reaction is stopped, a layer of polyaniline film is formed on the silicon substrate, and the yield is 38.22%. (2) Place the obtained polyaniline film in 0-50ml of benzene and let it stand for 1-12 months, and wash the obtained material to obtain a conductive polyaniline single crystal film that exists stably for a long time in the atmospheric environment. The electrical conductivity is 101.81 S / cm measured by the four-probe method, and the crystallinity is tested by XRD, and the crystallinity is calculated to be greater than 92.65%.

Abstract

A polyaniline material is high in chemical stability, however, the polyaniline material serving as an electronic device is low in environmental tolerance, and the service life of the whole device or the battery is restricted. If the problem can be solved, rapid development of new materials and new energy technology can be effectively promoted. The invention discloses a method for preparing a conductive polyaniline single crystal film material with long-term stable existence in an atmospheric environment. The method is simple in process, slight in environmental pollution and high in yield, the industrial production is easily realized, and the obtained polyaniline single crystal film is high in electric conductivity.

Description

technical field [0001] The invention relates to a method for preparing a polymer semiconductor single crystal thin film material, in particular to a method for preparing a polyaniline single crystal thin film material which exists stably for a long time in an atmospheric environment. Background technique [0002] Polyaniline with π-π conjugated structure not only has the density of plastics, but also has the machinability of plastics and the conductivity of metals, etc., and also has the electrochemical and chemical properties that metals and plastics lack. It has great application prospects in many hot fields such as lithium-ion batteries, fuel cells, supercapacitors, solar cells, photocatalysis, stealth materials, anti-corrosion materials, and antistatic. [0003] Although the polyaniline material has good chemical stability, its poor environmental tolerance as an electronic device still restricts the life of the entire battery or device. If this problem can be solved, it ...
