INFLUENCE OF THE FILLER, SILICE AND QUARTZ ON THE STRUCTURE AND ELASTIC MODULUS OF PDMS VULCANIZATED NETWORK

Abstract

The article presents the study results on the PDMS network vulcanizated with the filler, silice and quartz, by the differents techniques as strain, rheologie and Relaxation Magnetic Nuclear (RMN). The results dedicate the relation between the PDMS’s structure, detected by RMN and the elastic properties. Particularly, on the vulcanizated filled network, these spieces can have a same elastic modulus but different structures of networks, depending on the nature and the interaction between the PDMS molecule and the filler.
