Embodiment Construction

[0012] A preparation method of polyaniline-polyacrylic acid hydrogel, comprising the steps of:

[0013] (1) Mix 200 parts of an aqueous solution of an acrylic polymer with a concentration of 2% to 15% and a viscosity-average molecular weight of 10,000 to 500,000, and an aqueous solution of 0 to 200 parts of an alkali, at a temperature of 30°C to 80°C After stirring evenly, the solution is cooled to 20-30°C, and the concentration of the alkali is 0-2mol / l;

[0014] (2) Add 0.5 to 30 parts of aniline to the above solution cooled to 20°C to 30°C, stir to mix evenly to obtain a mixture, then cool the mixture until its temperature drops to 0°C to 5°C;

[0015] (3) Add 20 to 260 parts of oxidizing agent aqueous solution at 0°C to 5°C into the mixture and stir evenly, put it still under oxygen barrier, and react at 0°C to 5°C for 24 to 72 hours to obtain block The polyaniline-polyacrylic acid hydrogel, the concentration of the added oxidant is 0.5-5mol / l.

[0016] The viscosity-ave...

Abstract

An aqueous polyphenylamine-polyacrylic acid gel is prepared through mixing the aqueous solution of acrylic acid polymer with the aqueous solution of the alkali, further adding phenylamine and the aqueous solution of oxidant, and reaction. Its advantages are high electric conductivity, easy purifying (only immersing in water), and self-doping.

Description

technical field [0001] The invention relates to a preparation method of polyaniline-polyacrylic acid hydrogel. Background technique [0002] At present, there are many studies on the preparation of acrylic hydrogels by chemical crosslinking methods such as radiation and initiator initiation, and the preparation of hydrogels by this method is very mature. For example, add methacrylic acid monomer and a small amount of crosslinking agent - ethylene bismethacrylate in water, then add initiator - azobisisobutyrocyanide, stir well, and react at 60 °C for 8 Hours, polymethacrylic acid hydrogel can be obtained. Since a chemical cross-linking agent needs to be used, the manufacturing process and production cost are increased. In recent years, there have also been reports of polyaniline forming thermally reversible polyaniline gels in organic solutions (such as formic acid) and organic acid dopants. It is the combination of polyaniline and dopants (dodecylsulfonic acid) After mixi...
