EFFECT OF HYDRATION–DEHYDRATION PROCESSES ON THE STRUCTURE AND POROSITY OF DETEMPLATED SILICA FIBERS

A study was carried out on the conditions of template removal (calcination or extraction by solvents) and hydration.dehydration processes on the hexagonal structure and porosity of detemplated fibers. The hydration.dehydration cycle leads to a decrease in fiber porosity, especially in fiber detemplation by extraction with surfactant solvents such as ethanol and acetic acid.
