Abstract
Fluoroalkyl end-capped vinyltrimethoxysilane oligomer [RF-(CH2CHSi(OMe)3) n -RF; RF = CF(CF3)OC3F7; n = 2, 3: RF-(VM) n -RF] can undergo the sol–gel reaction in the presence of poly(styrene-co-butadiene) (SBR) under alkaline or acidic conditions, respectively, to afford the corresponding fluorinated oligomeric silica/SBR nanocomposites [RF-(VM-SiO2) n -RF/SBR]. Wettability control between superoleophobic and superoleophilic characteristics was observed on the modified superhydrophobic glass surfaces treated with these fluorinated nanocomposites. The nanocomposites, which were prepared under alkaline conditions, can provide a superoleophobic/superhydrophobic (superamphiphobic) characteristic on the modified surface; however, a superoleophilic/superhydrophobic characteristic was observed on the modified surface treated with the fluorinated nanocomposites, which were prepared under acidic conditions. Interestingly, the fluorinated nanocomposite particle powders possessing a superoleophilic/superhydrophobic characteristic were applied to the packing material for the column chromatography to separate not only the mixture of oil and water but also the W/O emulsion to isolate the transparent colorless oil. In addition, these particle powders were found to have a good reusability as the packing materials for the separation of the mixture of oil and water.
