以N-乙烯基己内酰胺,α-甲基丙烯酸为单体,合成温敏聚合物--聚(乙烯基己内酰胺-co-甲基丙烯酸),并利用静电纺丝技术将其制成纳米纤维。采用扫描电镜(SEM),傅立叶变换红外光谱(FT-IR),热重分析(TG)和微商热重法(DTG)对纤维进行表征。结果表明,通过调节纺丝液的浓度,可获得形态较好的纳米级纤维,并且该纤维在常规温度下可以保持纤维状,物理及化学性质不发生改变。 Using N-vinyl caprolactam and α-methacrylic acid as monomers, a thermo-sensitive polymer-poly (vinyl caprolactam-co-methacrylic acid) was synthesized and made into nanofibers by electrospinning. The fibers were characterized by SEM, FT-IR, TG and DTG. The results show that by adjusting the concentration of the spinning solution, a better shape of the nanofibers can be obtained, and the fibers can remain fibrous under normal temperature without any change of physical and chemical properties.
