Abstract

Ultrafine fibers of cellulose acetate/poly(butyl acrylate) (CA/PBA) composite in which PBA acted as an adhesive and CA acted as a matrix, were successfully prepared as fibrous mat via electrospinning. The morphology observation from the electrospun CA/PBA composite fibers, after treatment with heat hardener, revealed that the fibers were cylindrical and had point-bonded structures. SEM, FT-IR spectra, Raman spectra, TGA analysis, and mechanical properties measurement were used to study the different properties of hybrid mats. The tensile strength of blend fibrous electrospun mats was found to be effectively increased. This resultant enhancement of the mechanical properties of polymer fibrous mats, caused by generating the point-bonded structures (due to adhesive), could increase the number of potential applications of mechanically weak electrospun CA fibers.

摘要

成功制备了以聚（丙烯酸丁酯）（PBA）为黏合剂、醋酸纤维素（CA）为基质的 CA/PBA 复合超细纤维无纺毡，通过静电纺丝法制备。经过热固剂处理后，对电纺 CA/PBA 复合纤维的形态进行观察，结果表明纤维呈圆柱形，具有点结合结构。采用 SEM、FT-IR 光谱、拉曼光谱、TGA 分析和力学性能测试研究了混合毡的不同性能。发现共混纤维电纺毡的拉伸强度得到有效提高。由于生成了点结合结构（由于黏合剂），这种聚合物纤维毡力学性能的提高，可以增加机械强度较弱的电纺 CA 纤维的潜在应用数量。
