Silica gels that controlled the pore size were prepared by calcination of silica/organic polymer (50/50 wt %) composites prepared by the sol-gel process. Poly-(ethylene oxide) (PEO) -poly(propyrene oxide) (PPO) -PEO triblock copolymers, which are called poloxamers, were used as an organic polymer. T
Organosoluble polyimide/silica hybrid materials were prepared using the sol-gel process. The organosoluble polyimide was based on pyromellitic anhydride (PMDA) and 4,4Π-diamino-3,3Π-dimethyldiphenylmethane (MMDA). The silica particle size in the hybrid is increased from 100 -200 nm for the hybrid co
SiO 2 /TiO 2 /phosphate was obtained by the sol-gel processing method, having the following characteristics: specific surface area S BET = 800 m 2 g -1 , Ti = 14.8 wt% and P = 1.5 wt%, and ion exchange capacity of 0.58 mmol g -1 . The tetrakis(1-methyl-4-pyridyl) porphyrin ion, H 2 TmPyP 4+ , was im
