A novel composite oil-absorbent microsphere poly(stearyl methacrylate-co-butyl acrylate) (PSB)-SiO2 was prepared by introducing hydrophobic nano-silica Aerosil R812 into the suspension polymerization system of stearyl methacrylate and butyl acrylate and was characterized by Fourier transform infrared and scanning electron microscopy energy-dispersive spectrometer. PSB-SiO2 has a loose network structure and exhibits remarkably fast oil absorption speed in relatively high saturated oil absorbency. Besides, PSB-SiO2 has good oil retention and reusability. Moreover, the saturated oil absorbencies of PSB-SiO2 toward toluene, gasoline, and diesel over water are roughly equivalent to that in pure oil. Owing to its excellent oil absorption performances, PSB-SiO2 will find applications in removing oil spills and organic pollutants over water.
