Abstract

A high-performance elastomer was obtained by a multinetworking system of a covalent bond, hydrogen bond, and clay plane bond. By taking advantage of the characteristics of each cross-linking, the thermoplastic elastomer shows excellent compression set resistance, good flowability, and high tensile properties. The hydrogen bond gives flowability due to the bond cleavage under heating. The covalent bond contributes to the low compression set by prevention of polymer chain flow. Moreover, the clay plane bond affects the tensile properties by de-localization of the entire cross-link and increase of hysteresis energy between the clay plane surface and other cross-linking points. Furthermore, the self-healing properties and high heat resistance and recyclability were also observed.
