Polyester nanofiber can be prepared by electrospinning process from PET chips separately dissolving in three kinds of solvents,namely,the mixture solvent of phenol and tetrachloroethane,trifluoroacetic acid and the mixture solvent of trifluoroace- tic acid and dichlormethane.
利用静电纺丝法制备聚酯(PET)纳米纤维,选择苯酚和四氯乙烷,三氟乙酸,三氟乙酸和二氯甲烷3种溶剂分别溶解PET切片进行静电纺丝,通过扫描电子显微镜(SEM)对纤维表面形态进行观察,结果表明:三氟乙酸和二氯甲烷混合溶剂溶解PET制备的电纺纤维较好。
