A facile method for high-grafted surface modification of silica gel particles was developed in this paper Silica gel was obtained by traditional avenue and then reacted with urushiol (Chinese lacquer) The obtained product was characterized by FT-IR, elemental analysis, TGA, SEM, and EDX The results suggested that the reaction occurred between silica and urushiol and that the grafting ratio added up to 15 35 +/- 0 05 wt % The result of EDX demonstrated that the urushiol moieties were mainly on the surface of silica particles Additionally, the as-prepared silica particles had good dispersion
