Abstract
This review describes organic-inorganic polymer hybrids at molecular level. The sol-gel reaction of tetraalkoxysilane was carried out in the presence of organic polymers such as poly (2-methyl-2-oxazoline) and poly (N-vinylpyrrolidone). Transparent and homogeneous glassy materials were obtained in a wide range of the composition of organic polymers. In these polymer hybrids, hydrogen bonding between amide groups of organic polymer and silanol groups of silica gel plays an important role, which is supported by FT-IR spectra. Pyrolysis of these polymer hybrids at 600°C gave porous silica having controlled pore size. A wide variety of applications can be expected by using these molecular hybrids.
