Nonbonded and chemically bonded organic-inorganic composite materials, ABS/SiO 2 and ABSOSi(OCH 3 ) 3 /SiO 2 , were prepared by the sol-gel processing of tetraethoxysilane (TEOS) in the presence of ABS and trimethoxysilyl functionalized ABS, ABSOSi(OCH 3 ) 3 , under the catalization of NH 4 F. The A
Several types of nonbonded and chemically bonded composites of silica with linear and linear-nonlinear aramid polymers were prepared using the sol-gel process. The linear polyamide chains were synthesized by the reaction of a mixture of m-and p-phenylene diamines and terephthaloyl chloride in dimeth
Sol-gel-processed sintered silica xerogel was studied as a controllable, dissolvable, implantable material. The erosion of the matrix and the release of the preadsorbed drug toremifene citrate was investigated both in vitro and in vivo using mice. In an in vitro dissolution study, 50 to 60% of the d
