Poly(dimethylsiloxane) (PDMS) cross-linked films with different concentrations of micrometer-sized garnet particles were prepared through hydrosilylation reaction between a di-vinyl-terminated PDMS and a four-functional silane cross-linker in the presence of a Platinum catalyst. The garnet particles
## Abstract Mechanical properties and glass transitions of crossβlinked polymer networks depend strongly on both the network topology and crossβlinking density. A model is developed using a dynamic crossβlinking approach based on a cutoff distance criterion followed by a highβtemperature annealing
