摘要:
采用无皂乳液聚合,以过硫酸钾(K2S2O8)为引发剂、苯乙烯(St)为疏水单体、甲基丙烯酸缩水甘油酯(GMA)为亲水单体与亲/疏水性各异的交联剂进行反应,制备交联异形聚苯乙烯-聚甲基丙烯酸缩水甘油酯(PSt-PGMA)聚合物纳米球.利用扫描电镜、动态光散射、红外光谱、热重分析等手段对材料进行表征,探讨异形聚合物纳米球形貌的调控方法和形成机理.结果表明,交联剂的亲/疏水性是控制聚合物纳米球形态的关键因素.该聚合物纳米球可作为Au纳米粒子载体用于催化对硝基苯酚的还原反应.同时,通过垂直沉积法诱导尺寸各异的交联异形PSt-PGMA聚合物纳米球自组装,可获得颜色从红到紫连续变化的光子晶体材料.
Abstract:
Poly(styrene-co-divinylbenzene-co-polyglycidyl methacrylate)(PSt-PDVB-PGMA)polymer nanospheres with tunable morphologies have been prepared through emulsion polymerization using potassium persulfate(K2S2O8)as an initiator,styrene(St)and glycidyl methacrylate(GMA)as monomers in the presence of different crosslinking agents.Scanning electron microscope(SEM),dynamic light scattering(DLS),thermogravimetric analysis(TGA)and Fourier transform-infrared spectroscopy(FT-IR)were used to characterize the morphology,size and composition of the polymer nanospheres.The mechanism for the formation of asymmetric polymer nanospheres and control over morphology were discussed in detail.It was found that the hydrophilicity of the crosslinking agent significantly affected the final morphology of the polymer nanospheres.The PSt-PDVB-PGMA polymer nano-spheres can be used as supports for Au nanocatalyst to catalyze the reduction of nitrophenol and self-assembly building blocks to form photonic crystals.
