摘要：

Oil contaminated water has resulted in so many disastrous consequences that serviceable method for removing oil from water is urgently needed. In the present study, we successfully manufactured superhydrophobic fiberglass cloth based on the formation of amino-silica particles and subsequent hydrophobization using octadecyltrichlorosilane. Meanwhile, sticky epoxy resin was worked as a caking agent by adhering abundant of amino-silica particles to glass fiber surfaces. The relevant results disclosed that silica and octadecyltrichlorosilane reagent existed on superhydrophobic fiberglass cloth with water contact angle of 154 degrees and sliding angel of 5 degrees, moreover, the as-prepared fiberglass cloth exhibited outstanding water-oil separation property with separation efficiency of 98%.
