Hybrid inorganic-organic gels

According to the classification proposed by Judeinstein and Sanchez (1996), organic-inorganic hybrid gels can be divided into two classes class 1 corresponds to sohds with weak bonding between the organic and inorganic parts, while class 11 corresponds to solids where both parts are chemically bonded.

Sol-gel chemistry offers a unique advantage in the creation of novel organic-inorganic hybrids. The sol-gel process begins with a solution of metal alkoxide precursors [M(0/f) ] and water, where M is a network-forming element, and R is typically an alkyl group. Hydrolysis and...
