摘要:
以烯丙基聚醚、氯化亚砜和十四烷基二甲基叔胺为原料合成一种新型的可聚合季铵盐表面活性剂,并用该表面活性剂对纳米SiO2粉体进行表面改性,采用傅里叶变换红外光谱仪(FT-IR)、核磁共振氢谱仪(1H-NMR)、界面张力仪、热分析仪、粒度分析仪和紫外-可见分光光度计对样品进行表征。结果表明:可聚合季铵盐表面活性剂的临界胶束浓度为4.47×10-3 mol/L,对应的表面张力为38.12 mN/m,改性纳米SiO2粉体的最大接枝量为27.0 mmol/g,且在甲醇、乙酸乙酯、甲苯、正己烷等溶剂中都具有较好的分散稳定性。
Abstract:
Nano-SiO2 particles were modified by a novel kind of polymerizable quaternary ammonium surfactant synthesized by allyl-poly(ethylene glycol),thionyl chloride and tetradecyl dimethyl amine.The samples were characterized by Fourier transform infrared spectroscopy(FT-IR),hydrogen nuclear magnetic resonance spectrometer(1H-NMR),interface tensiometer,thermal analysis,particle size analyzer and ultraviolet-visible spectrophotometer.Results indicated that the critical micelle concentration and surface tension of the polymerizable quaternary ammonium surfactant were 4.47×10-3 mol/L and 38.12 mN/m,respectively.The maximum grafting amount of modified nano-SiO2 particles was 27.0 mmol/g,and it could be well dispersed in methanol,ethyl acetate,toluene and hexane.
