摘要: All siloxane-type siloxane–polyhedral oligomeric silsesquioxane [(HSiO3/2)8, T8H] copolymers were synthesized by the dehydrogenative condensation of T8H with diphenylsilanediol, tetraphenyldisiloxane-1,3-diol or silanol-terminated polydimethylsiloxanes in presence diethylhydroxylamine followed trimethylsilylation. Coating films prepared spin-coating coating solutions from products. The hardness was evaluated a pencil test and found to increase up 6H increases curing temperature. Silica gels concentrating solution following pyrolysis. These silica showed specific surface area 449 m2/g at 650 °C corresponding formation network response combustion phenyl groups.
