Recent Advances in Polypyrrole Hydrogels: A Brief Review

Abstract

In recent years, scientific research on new materials has gradually increased, most of which being part of our daily lives. Among these materials, we can focus on conductive polymers such as polypyrrole (PPy), which has a variety of properties, such as electrical conductivity, good chemical stability and excellent biocompatibility. This combination of properties for applications in the form of hydrogels enables a wide area of applications. Some of these hydrogels can be exemplified in this brief review containing explanatory topics to guide the proposed study. We evidenced that in the last 25 years, not only have scientific articles increased in research databases, but also requests for patent deposits.
