Abstract
This invention discloses a polyacrylic acid / choline chloride / hydroxyethyl cellulose / polyaniline eutectic gel electrode material and its preparation method, belonging to the field of flexible electronic materials technology. First, a polymerizable eutectic system is constructed using choline chloride and acrylic acid. Then, hydroxyethyl cellulose is added and dissolved uniformly. Next, a polyacrylic acid / choline chloride / hydroxyethyl cellulose eutectic gel is prepared by photo-initiated polymerization. This eutectic gel is then placed in a mixed solution of aniline for low-temperature swelling and infiltration, initiating in-situ polymerization of aniline to obtain the polyacrylic acid / choline chloride / hydroxyethyl cellulose / polyaniline eutectic gel electrode material. The eutectic gel electrode material prepared by this invention exhibits good flexibility, excellent mechanical and electrochemical properties, outstanding temperature and freeze resistance, and is environmentally friendly and low-cost, showing great development potential.
