静电纺纳米纤维由于其显着的微米和纳米特性以及高表面积与体积比相关，成为一个快速发展的新研究领域。以过氧硫酸钾为引发剂，在水介质中通过沸点无皂乳液聚合合成了苯乙烯-丙烯酰胺共聚物和聚苯乙烯聚合物。将所得聚合物溶解在二甲基甲酰胺和四氢呋喃 (DMF: THF) (4:1) 中，形成聚合物溶液，将其电纺成直径分别为 1.84 - 2.53 μm 和 5.01 μm 的纤维垫。通过配备通用 ATR 采样附件 (4000 - 400 cm-1) 的傅里叶变换红外光谱 (FTIR) 对纤维进行表征。通过扫描电子显微镜（SEM）检查形态和尺寸，通过热重分析（TGA）检查热性能。聚（苯乙烯-丙烯酰胺）的 FTIR 光谱表明聚苯乙烯链上存在丙烯酰胺。因此，可以在静电纺丝之前的一步聚合反应中用丙烯酰胺对聚苯乙烯进行表面改性。
Electrospun nanofibers present a new and rapidly growing research area due to their pronounced micro and nano characteristics associated with high surface area to volume ratio. Poly(styrene-co-acrylamide) and polystyrene polymers were synthesized by boiling temperature soap free emulsion polymerization in aqueous medium with potassium peroxosulphate as the initiator. The resulting polymers were dissolved in dimethylformamide and teterahydrofuran (DMF: THF) (4:1) to form polymer solutions that were electrospun into fiber mats with diameters ranging from 1.84 - 2.53 μm and 5.01 μm, respectively. The fibers were characterized by Fourier transform infrared spectroscopy (FTIR) equipped with universal ATR sampling accessory (4000 - 400 cm-1). The morphology and size were examined by a scanning electron miscroscope (SEM) and the thermal properties by thermogravimetric analysis (TGA). The FTIR spectra of the poly(styrene-co-acrylamide) revealed the presence of acrylamide on the polystyrene chain. Thus, surface modification of polystyrene with acrylamide is possible in a single step polymerization reaction prior to electrospinning.
