Phase inorganic

Transparent, homogeneous hybrids using a 50 50 PVAc-to-TEOS mixture and an acid-catalyzed reaction have been produced and characterized by dsc and dms (46). Dsc indicated only a slight increase in the T of the hybrid with incorporation of sihca. Dynamic mechanical tan 8 responses indicate a strong interaction between the organic and inorganic phases and, hence, weU-dispersed phases that lead to high modulus mbbery plateaus.

Depending on the level of interaction between these organic-inorganic phases, hybrid materials can either possess weak interaction between these phases such as van der Waals, hydrogen bonding, or electrostatic interaction [7,8], or be of strong, chemically bonded (covalent or coordinate) types [9].

Greater size of the silica particles indicates higher extent of poly condensation that has taken place in the inorganic phase. The generation of silica particles is directly proportional to the alkoxysilane concentration and higher concentration of TEOS used for these investigations allows higher extent of...

Many binary inorganic phases with a significant composition range can be listed1 (Table 4.3). Apart from binary compounds, ternary and other more complex materials may show nonstoichiometry in one or all atom components.
