Abstract
Abstract Mesoporous silicas have been synthesized by templating of a linear diblock copolymer, poly(ethylene glycol-b-propylene glycol) in the neutral aqueous solution. The N2 adsorption behavior with the Barrett-Joyner-Halenda(BJH) method showed monodisperse pore size distribution. The high-resolution scanning electron micrograph showed that the pore size ranges 20 to 80nm. The results were compared to those templates by a triblock copolymer, poly(ethylene glycol-b-propylene glycol-b-ethylene glycol).
