静电纺丝制备Tb-PEG+Eu-PEG/PANI/PAN荧光导电相变三功能复合纤维

静电纺丝制备Tb-PEG+Eu-PEG/PANI/PAN荧光导电相变三功能复合纤维

论文摘要

以聚丙烯腈(PAN)为载体基质、以铕-聚乙二醇(Eu-PEG)和铽-聚乙二醇(Tb-PEG)为相变荧光材料,加入掺杂的导电聚苯胺(PANI),采用静电纺丝技术制得Tb-PEG+Eu-PEG/PANI/PAN复合纤维.采用扫描电子显微镜(SEM)、荧光光谱(FL)仪、差示扫描量热(DSC)仪及宽频介电松驰谱(BDS)仪等方法对相变荧光导电复合纤维的性能进行分析.研究结果表明,复合纤维具备良好的荧光、相变及导电性能.在294 nm紫外光激发下,通过调节Tb-PEG和Eu-PEG的质量比可调节复合纤维的发光强度和颜色,同时复合纤维的相变温度在54~67℃之间.复合纤维的电导率达到10-6S/cm,随着PANI含量的增加,电导率和介电常数增加.通过调节Tb-PEG,Eu-PEG和PANI的比例及PEG的分子量,可以实现复合纤维荧光、导电及相变性能的可控调整.
