| Abstract: | Small molecular surfactant (SMS) such as HDC-193 was encapsulated into mesoporous silica SBA-15 and 3-aminopropyltriethoxysilane-modified SBA-15 (mSBA-5) to develop new controlled release SMS system. The diffusion process of HDC-193 from mesoporous silica with different structures and diameters was investigated. Both situations of large pore and organic modification promoted the adsorption and thus a larger load of SMS in mesoporous silica. The results of molecular dynamics simulations and washing durability experiments showed that the lifetime of HDC-193 encapsulated into mSBA-15 in polystyrene blends is five times longer than that of HDC-193/polystyrene. This suggests an efficient strategy for designing permanent antistatic agents. |
