静电纺丝是近几年间流行起来的新型技术,它在微纳米级别的双级粗糙微观结构上优势突出。基于静电纺丝的方法来制备纳米纤维材料具有很多较好的工业性能,比如制得的纤维具有直径可以调整、形貌可以控制、较好的孔隙率以及组织均一等优点,此外还具有较规律的取向性和排列性。静电纺丝设备可以通过调节参数以喷雾和喷丝两种形式进行生产,以静电喷雾喷出聚苯乙烯(PS)微球,再通过改变溶剂二甲基甲酰胺(DMF)、挥发性溶剂四氢呋喃(THF)的比例以及PS的溶质含量分别研究电纺膜的形貌以及疏水性、稳定性等性能。微球相较于纤维结构具有更高的粗糙表面以及更高的比表面积,体现出较高的疏水性。改变PS浓度以及THF与DMF的数值,得到相对性的疏水性变化趋势。
Electrospinning is a new technology popular in recent years.It has outstanding advantages in two-stage rough microstructure of micro and nano scale.The nano-fiber materials prepared by electrostatic spinning have many good industrial properties,such as the fiber adjustable diameter,controllable morphology,good porosity and uniform structure,as well as the regular orientation and arrangement.Electrostatic spinning device products in two forms:spraying jet or silk by adjusting parameters.This article was based on electrostatic spray jet to form PS microspheres.By changing the solvent dimethyl formamide (DMF),the proportion of tetrahydrofuran (THF) and PS content of solute,respectively,the morphology of electrospinning film,hydrophobic property and stability performance were investigated.Compared with fiber structure,microspheres had higher rough surface and higher specific surface area,showing higher hydrophobicity.The relative hydrophobicity trend was obtained by changing PS concentration and THF:DMF value.
