摘要
先以丙烯腈和丙烯酸为单体合成聚合物(Polymer-1),用荧光染料对聚合物进行接枝改性后得到聚合物(Polymer-2);然后将这两种聚合物通过静电纺丝法制备出纳米纤维毡。研究了单体配比对Polymer-1共聚物粘均分子质量的影响;用DSC和IR测试手段对聚合物结构进行表征,用SEM和荧光光谱分析(FS)测试手段对纳米纤维毡的微观形状和荧光性能进行测试。结果表明,成功制备出荧光改性聚合物Polymer-2,获得了具有荧光性能的纳米纤维毡。
In this paper,Polymer-1 was synthesized by acrylonitrile monomer and acrylic monomer,and polymer-2 was the modified product when polymer-1 was grafted with fluorescent dyes.Then two polymers＇ nano-fiber mats were prepared through electrospinning process（ESP）.The influence of the monomer ratio on Polymer-1＇s viscosity average molecular weight was studied.DSC and IR were used to characterize the polymer firstly,SEM and Single-photon fluorescence spectra（FS） were used to test the nano-fiber mats.The results demonstrate that the fluorescent copolymer（Polymer-2 ） was prepared successfully and nano-fiber mats with fluorescent properties could be obtained using ESP technology.
