Network hybrid

As an organic polymer, poly(tetramethylene oxide) was also used for the preparation of ceramers. The mechanical properties in these cases were much improved in comparison with those for hybrids from polysiloxanes. In these poly (tetramethylene oxide)-silica hybrids, the effect of the number of functional triethoxysilyl groups was examined [13]. As shown in Fig. 2, more multifunctional organic polymer produced more crosslinked hybrid networks. This means that the more rigid the structure in the hybrids is, the higher the modulus and the lower swelling property.

This new family of mesoporous silica and aluminosilicate compounds were obtained by the introduction of supramolecular assemblies. Micellar aggregates, rather than molecular species, were used as structure-directing agents. Then, the growth of inorganic or hybrid networks templated by structured surfactant assemblies permitted the construction of novel types of nanostructured materials in the mesoscopic scale (2-100 nm) [110,113,117],... 

Coordination Polymers and Hybrid Networks of Different Dimensionalities Formed by Metal Sulfites... 

In conclusion, zinc sulfite-based coordination polymers and hybrid networks of different dimensionalities have been synthesized and characterized. An open-framework hybrid sulfite—sulfate, where both SO32- and S042- are part of a two-dimensional layer, has also been synthesized and characterized. On the basis of the present studies, it appears that many more metal sulfite-based open-framework and hybrid materials can be synthesized. 

Dynamic self-assembly of supramolecular systems prepared under thermodynamic control may in principle be connected to a kinetically controlled sol-gel process in order to extract and select the interpenetrated hybrid networks. Such dynamic convergence between supramolecular self-assembly and inorganic sol— gel processes, which synergistically communicate, leads to higher self-organized hybrid materials with increased micrometric scales.

Earlier studies (1-4) reported from this laboratory demonstrated that functionalized PDMS can be successfully incorporated into a hybrid network by using TEOS as the metal alkoxide. When analyzed for structural features. 

In all cases, the solid-state NMR ( Si and C) spectra showed the presence of the organic fragment whatever the catalyst used (acid or base). Only T, C-Si(OSi)2(OR) and T, C-Si(OSi)3 are observed from Si NMR, proving the preserved Si-C bonds in the hybrid network after the hydrolysis-condensation process.
