Abstract

Poly(dimethyl siloxane) (PDMS) is widely used in a variety of industrial and commercial applications, including seals, bladders, and biological applications. While most PDMS elastomers posses some ability to self-heal through surface cohesion, the mechanism is generally insufficient to produce significant recovery of initial material strength. Here we report the development of a self-healing PDMS elastomer based on the embedding of two microcapsule types, a resin capsule and an initiator capsule. The healing efficiency of this material was investigated using a trouser tear test. These tests have shown that the material can recover, on average, 76% of the virgin tear strength and in limited cases can exhibit 100% strength recovery.
