摘要

Octavinyl-polyhedral oligosilsesquioxanes(OVPOSS) was synthesized via hydrolysis and condensation reaction. The organic-inorganic hybrid materials were produced with OVPOSS and polymethylmethacrylate (PMMA) self-curing resins. The hybrid materials were characterized with FTIR, XRD, TEM, SEM, DSC, plastic ball indentation hardness tester, high-temperature friction, wear tester and memory-type cantilever beam impact testing machine. Particularly, morphology and compatibility properties of hybrid materials and OVPOSS particles were discussed. The results indicated that the size of OVPOSS crystal structure began to reduce with the addition particles in the hybrid materials. The compatibility properties show that phase separation occurs in the hybrid systems with higher content of POSS.
