Candidates for smart robotics: Self-healing conductive composites were prepared by connecting single-walled carbon nanotubes (SWCNTs) to a polymer network through host–guest interactions (see picture). The poly(2-hydroxyethyl methacrylate)–SWCNT composite combines bulk electrical conductivity, proximity sensitivity, humidity sensitivity, and autonomic self-healing properties.
Abstract
Healable, electrically conductive materials are highly desirable and valuable for the development of various modern electronics. But the preparation of a material combining good mechanical elasticity, functional properties, and intrinsic self-healing ability remains a great challenge. Here, we design composites by connecting a polymer network and single-walled carbon nanotubes (SWCNTs) through host–guest interactions. The resulting materials show bulk electrical conductivity, proximity sensitivity, humidity sensitivity and are able to self-heal without external stimulus under ambient conditions rapidly. Furthermore, they also possess elasticity comparable to commercial rubbers.
