Surface-initiated atom transfer radical polymerization (SI-ATRP) is one of the most versatile techniques to modify the surface properties of materials. Recent developed metal-free SI-ATRP makes such techniques more widely applicable. Herein photo-induced metal-free SI-ATRP of methacrylates, such as methyl methacrylate, -isopropanyl acrylamide, and ,-dimethylaminoethyl methacrylate, on the surface of SBA-15 was reported to fabricate organic-inorganic hybrid materials. A SBA-15-based polymeric composite with an adjustable graft ratio was obtained. The structure evolution during the SI-ATRP modification of SBA-15 was monitored and verified by FT-IR, XPS, TGA, BET, and TEM. The obtained polymeric composite showed enhanced adsorption ability for the model compound toluene in aqueous conditions. This procedure provides a low-cost, readily available, and easy modification method to synthesize polymeric composites without the contamination of metal.
表面引发原子转移自由基聚合（SI-ATRP）是改变材料表面性质的最通用技术之一。最近发展起来的无金属SI-ATRP使该技术的应用更加广泛。本文报道了在SBA-15表面进行甲基丙烯酸酯（如甲基丙烯酸甲酯、异丙基丙烯酰胺和甲基丙烯酸二甲氨基乙酯）的光引发无金属SI-ATRP，以制备有机-无机杂化材料。获得了具有可调接枝率的基于SBA-15的聚合物复合材料。通过傅里叶变换红外光谱（FT-IR）、X射线光电子能谱（XPS）、热重分析（TGA）、比表面积分析（BET）和透射电子显微镜（TEM）对SBA-15进行SI-ATRP改性过程中的结构演变进行了监测和验证。所制备的聚合物复合材料在水相条件下对模型化合物甲苯表现出增强的吸附能力。该方法提供了一种低成本、易于获得且简便的改性方法，用于合成无金属污染的聚合物复合材料。
