Structural Characterization, Crosslinking and Pyrolysis Investigation of Carbosilane Oligomers

Abstract:

Article Preview

Carbosilanes synthesized from high-pressure treatment of polysilane, were fractional distilled and separated. Carbosilanes, characterized by IR and 1HNMR measurement, are composed of linear and cyclic carbosilanes with some Si-H end groups. Crosslinking occurred between carbosilanes and divinyl benzene and gave gel content of 52%, and further ceramic yield of 36% upon pyrolysis at 1200°C. The pyrolyzates contain microcrystal SiC and free carbon, which was approved by XRD measurement.
