Preparation of Hierarchical Porous Methylsilicone Monoliths with Monodisperse Polystyrene Microspheres as Template

Abstract:

Hierarchical porous methylsilicone monoliths were prepared by filling monodisperse polystyrene microsphere (PS) as template and subsequently removing PS in selective solvent. The hierarchical porous structure can be tailored by adjusting the reactant ratio. The textural structure were investigated by the measurement of density, SEM observation, and N₂ desorption and adsorption isotherm and pore size distribution. The results showed the hierarchical porous methylsilicone materials with interconnected macropores and mesopores were lightweight and hydrophobic.
