Origins of Material Failure in Siloxane Elastomers from First Principles
Material failure under tensile stress limits the range of technical applications of siloxane materials. By using first‐principles simulations, the authors show that a single siloxane chain can tolerate high mechanical load, but once it is broken, the resulting ions easily attack neighboring chains,...

| description | Material failure under tensile stress limits the range of technical applications of siloxane materials. By using first‐principles simulations, the authors show that a single siloxane chain can tolerate high mechanical load, but once it is broken, the resulting ions easily attack neighboring chains, thus destabilizing the network (see figure; Si: grey, O: red, C: black, H: gold). |
