The Microstructure and Mechanical Property of Meta-Aramid Nanofiber Web for High Temperature Filter Media

Abstract:

The meta-aramid nanofiber webs were successfully prepared by electrospinning with the solvent system LiCl/DMAc in this paper. The uniform nanofibers were obtained when the concentration of the spinning solution was larger than 9wt%, and the microstructure and physical properties of the nanofiber webs were examined. To date, the webs had a better mechanical property when the concentration of the spinning solution was 11wt%. Whereafter, we mainly investigated the effects of heating temperature on the properties of the mate-aramid nanofiber webs. After heat treatment, the structure and property change of the nanofiber webs were analyzed by means of SEM, XRD, TGA, and the tensile strength was measured by Kawabata Evaluation System (KES). The results indicated that there was no significant weight loss and retained a favourable mechanical property when the heating temperature was below 200°C, however, the properties of nanofiber webs would decrease if the heating temperature were increased or the heating time was more prolonged.
