摘要

近年来，随着仿生疏水表面的火热发展，科学家们对超疏水材料的研究也越来越热衷，近年来科学家们对此开展很长时间多方面的研究，这其中纳米纤维复合膜无纺布因为他的表面积大，多孔性，超疏水性等因素，在防腐去污等领域有着极其重要的发展潜力。

本文章在利用静电纺丝的技术，制备了多孔不同浓度的PS与PDMS的纳米纤维无纺布，考察不同浓度的PDMS所形成的纳米纤维膜形貌特征，以及其润湿性的影响因素，并利用实验室接触角测定仪、光学显微镜等仪器，对PS与PDMS复合纳米纤维膜的物理性质来推测其疏水性与纤维表面接触角的影响，实验表明，PS与PDMS复合纳米纤维膜的纤维形貌与润湿行为都与PDMS的浓度有一定的关系。

Abstract

In recent years, with the development of bionic fiery hydrophobic surface, scientists study of super-hydrophobic materials are increasingly keen, widely superhydrophobic materials applications, such as ship corrosion, rust metal, long-distance transmission and oil fields in the clothing waterproof stain clothing. In recent years, scientists have conducted extensive research on this for a long time, which nanofiber nonwoven composite film because of his large surface area, porosity, superhydrophobic and other factors, in areas such as antiseptic decontamination has an extremely important development potential, the paper around their wetting behavior of composite fiber morphology was studied.

The absorbent article of nanofiber membrane using electrostatic spinning techniques, a porous PDMS with different concentrations of PS nano-fiber nonwoven fabric, the effects of different concentrations of PDMS is formed, and the effect of water separation characteristics, and use of contact angle measurement laboratory, optical microscopes and other equipment, the physical properties of PS and PDMS composite nanofiber membrane to speculate affect its hydrophilic and oil-water separation characteristics, experiments show that the hydrophilic PS and PDMS composite nanofiber membranes and oil-water separation characteristics are related to the concentration of PDMS has a great relationship. .

Keywords:PS and PDMS composite fiber membranes、electrospinningnanofibers、Composite fiber wetting behavior
