The synthesis and thermal curing of aryl-ethynyl terminated coPOSS imide oligomers: new inorganic/organic hybrid resins

摘要

Polyhedral Oligomeric SilSesquioxanes (POSS), a family of nanoscale inorganic cage structures consisting of a silicon and oxygen framework, have attracted significant attention due to their unique physical and chemical properties. The incorporation of POSS moieties in inorganic/organic hybrid materials are expected to introduce the desirable properties of POSS such as abrasion resistance, thermal stability, and increased oxidative and ultraviolet stability to the bulk properties of such materials. Although the use of POSS bearing polymerizable substituents in the synthesis of organic polymers has afforded hybrid materials consisting of an organic backbone with pendent POSS units, simple methods of incorporating POSS cages into useful materials remains relatively sparse.
