✦ Synopsis

In sol-gel F ro 'cessing the pore structure of the dry gel (xerogel) or film is a -_ consequence o the sequential (or overlapping) gelation, aging, and drying stages. This paper demonstrates how the surface area, pore volume, and pore size are influenced by such physical and chemical factors as the size, structure and composition of the inorganic polymers, the magnitude of the capillary pressure, conditions of aging, and choice of pore fluid.

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
