Hybrid materials alkoxide group

In recent years, silica sol-gel-based inorganic-organic hybrid materials have also been reported. The introduction of various functional groups into organic alkoxide has led to organically modified sol-gel glasses (ormosils). Some of the ormosil monomers and ormosil formations can be found in Fig. 16.3. Redox molecules can be coupled with the ormosil monomer functional group. The immobilized redox molecules can... 

Figure 4 Polymer-silica hybrid materials hydrogen bonding between silanol groups of hydrolyzed silicon alkoxides and carboxylate groups of preformed poly(A, A-dimethylacrylamide) (a) or in situ polymerized A, A-dimethylacrylamide/methylene bisacrylamide precursors (b) favors the formation of homogeneous organic-inorganic networks...

Substituting a certain part of the alkoxidic groups by nonhydrolysable ones, such as alkyl groups in the case of alkoxysilanes or phosphonic acid in the case of metal alkoxides, organically modified oxides, i.e. inorganic-organic hybrid materials, have been prepared. 

The further study on sol-gel preparation of MEEP-silicate composite materials involved the synthesis of a polyphosphazene precursor via the covalent linkage of MEEP with an organometallic alkoxide (triethoxysilane group) [63]. The following hydrolysis and condensation produced a covalently interconnected hybrid material with controlled morphologies and physical properties. A maximum ionic conductivity of 7.69 X10 S cm was achieved for the composite materials complexed with LiTFSI salt.
