对叔丁基酰胺化杯[8]芳烃/聚丙烯腈纳米纤维的制备

Preparation of amide-t-butylcalix[8] arene/polyacrylonitrile nanofibers by electrospinning

采用静电纺丝技术制备了对叔丁基酰胺化杯[8]芳烃/聚丙烯腈(Amide-Cal[8]/PAN)复合纳米纤维,并通过傅里叶变换红外光谱(FTIR)仪、场发射扫描电镜(FE-SEM)、电导率仪、转矩流变仪对其结构与性质进行表征.实验结果表明:①Amide-Cal[8]/PAN纳米纤维的直径较空白的PAN纳米纤维小;②随着Amide-Cal[8]含量的增加,纳米纤维的直径先减小后增大,且纤维表面的粗糙程度逐渐增加,粗细不均;Amide-Cal[8]/PAN电纺溶液的黏度随着Amide-Cal[8]含量的增加而线性增大;③Amide-Cal[8]/PAN电纺溶液比PAN溶液的电导率大,有利于静电纺丝.

Amide-t-butylcalix[8] arene/polyacrylonitrile （Amide-Cal[8]/PAN） nanofibers were prepared by electrospinning. The nanofibers were characterized by fourier transform infrared spectroscopy （FTIR）, field emission scanning electron microscope （FE-SEM）, conductivity meter, torque rheometer. The results showed that Amide-Cal[8-]/PAN was successfully prepared by electrospinning. The diameter of nanofibers was smaller than that of the blank PAN nanofibers. Moreover, the surface of nanofibers was smooth and uniform, but with the Amide-Cal[8] content increased, diameter of nanofibers and the surface roughness were increased. Rheometer results indicated that the viscosities of Amide-Cal[8]/PAN spinning solutions were increased with the increase of Amide- Cal[8] content. Conductivity results showed that the electrical conductivities of Amide-Cal[8]/ PAN spinning solution were higher than that of pure PAN solution and it was conducive to electrospinning.
