| Abstract: | 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. Copyright © 2016 John Wiley & Sons, Ltd. |
