摘要：
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.
