Mechanical and thermal degradation behavior of high-performance PDMS elastomer based on epoxy/silicone hybrid network

In this study, the high-performance PDMS elastomer was successfully prepared by constructing epoxy/silicone hybrid network through hydrosilylation and epoxide-opening reaction. The tensile strength, elongation at break and shear strength of the prepared hybrid material were increased by 200.0%, 59.6%, 140.6% respectively when compared with the pure PDMS. The thermal residual weight of the hybrid material at 800 °C in N2 was kept at 56.9%. The...
