Synthesis and Properties of Inorganic/Organic Hybrid Gels by the Sol-Gel Process

摘要: The preparation of inorganic/organic hybrid gels was carried out using tetraethoxysilane and organic polymers via the sol-gel process. Hydroxyl terminated siloxane were reactive enough to be incorporated into silica networks. However, hydroxyl polyethers, i.e., poly(oxyethylene), poly(oxypropylene), poly(oxy-tetramethylene), failed react, thus most them extracted by solvents. introduction triethoxysilyl groups in these found very effective prepare truly resulted optically transparent mechanically more or less elastic. structures mechanical properties flexible materials investigated. polymer glass formed matrix depending on composition gel, other component dispersed matrix. Dynamic which predominant components, explained accord with structural considerations. Noise vibration attenuating are suggested as one possible applications from their loss behaviors.
