Hybrid inorganic-organic polymer model

Modification of CaO-Si02 system with organic polymer may provide bioactive organic-inorganic hybrids. Tsuru et al. [71] prepared polydimethylsiloxane (PDMS)-CaO-Si02 hybrids by a sol-gel method. Tetraethoxysilane (TEOS) was hydrolyzed and reacted with PDMS, and calcium nitrate (Ca(N03)2) was incorporated. The model structure of the PDMS-... 

Silicone co-polymer networks and IPNs have recently been reviewed.321 The development of IPNs is briefly described, and the definitions of the main (non-exclusive) classes of the IPNs are cited. Examples of latex IPNs, simultaneous and sequential IPNs, semi-IPNs, and thermoplastic IPNs are provided. The use of silicone-silicone IPNs in studies of model silicone networks is also illustrated. Networks in which siloxane and non-siloxane components are connected via chemical bonds are considered co-polymer networks, although some other names have been applied to such networks. Today, some of the examples in this category should, perhaps, be discussed as organic-inorganic hybrids, or nanocomposites. Silicone IPNs are discussed in almost all of the major references dealing with IPNs.322-324 Silicone IPNs are also briefly discussed in some other, previously cited, reviews.291,306...
