Research progress in polymer ionic gel matrix system, modification methods and applications

Abstract

Polymer ionic gel is a new type of gel system composed of ionic liquid (IL) and polymer matrix, which has excellent extensibility, high conductivity and good stability. It has broad application space in the field of flexible electronic products, and has attracted the attention of researchers at home and abroad. Based on the investigation of the research progress in related fields in recent years, the matrix classification of polymer ionic gel materials was summarized, the modification methods of conductive hydrogels were discussed, the application of ionic gel in related fields was expounded, and on this basis, the challenges faced by polymer ionic gel and its future development direction were summarized and prospected. It was pointed out that the development of ionic gel with excellent mechanical properties, high conductivity and degradability is the focus of future research. At the same time, improving the environmental stability of ionic gel and reducing the preparation cost of ionic gel are urgent problems to be solved in practical applications. The preparation and application of ionic gel will promote the rapid development of flexible electronic materials.
