The Effect of Technological Factors on Electric Conductivity of Filled Silicon Elastomers

摘要

There is effect of some technological factors (kind and content of fillers, olygomer additions, vulcanization method) on the technical characteristics of filled silicon rubbers on the polydimethylvinylsiloxan (SKTN) base investigate. It is established that these factors essentially influence the microstructure of composites and connected with its conductive network. It has been shown that the higher indexes belongs composites which are produced by the method of filling polymerization and especially with using alteration by various siliconorganic components of thermally splitted graphite. The density of vulcanization network is estimated by the application of sol-analysis method, while NMR method is applied for a estimation of macromolecules in the composites and sensitivity of materials to external deformation.
