Facile synthesis of multi-functional elastic polyaniline/polyvinyl alcohol composite gels by a solution assembly method.

ABSTRACT: Polyaniline gels with a three-dimensional network structure are attractive for their broad application prospects in flexible and stretchable electric devices. In this paper, we develop a facile solution assembly method to prepare an elastic polyaniline/poly(vinyl alcohol) composite organogel and a hydrogel. The polyaniline and poly(vinyl alcohol) chains gelate from the homogeneous mixed solution in N-methyl-2-pyrrolidone via crystallization of poly(vinyl alcohol), producing a uniform organogel with hydrogen bonds between two polymers, and the organogel can be further converted into a hydrogel by solvent exchange. The composite gels exhibit excellent mechanical properties, which make them one of the best materials for additive manufacture, such as molding and 3D printing. This
