摘要/Abstract

摘要： 采用静电纺丝法,通过调节电纺母液浓度,制备出7种具有典型微米颗粒结构、微米颗粒/纳米纤维混合结构和纳米纤维结构的疏水表面,实现了纳微结构的表面可控;对表面微观结构进行了表征,测试了其疏水性能;通过表面结霜过程和抑霜性能实验比较,结合表面分形维数分析,研究了纳微结构疏水表面的抑霜特性。结果表明,虽然7种纳微结构疏水表面接触角均在139°~152°之间,具有明显的疏水特性,但其抑霜性能与疏水性能并不呈一致关系;抑霜性能与表面结构密切相关,随着表面结构分形维数的增大而减小。

Abstract: Seven kinds of hydrophobic surfaces,which have the typical characteristics of micron particle structure,mixed structure of micron particle and nano-fiber,and nano-fiber structure with the surfaces of nano/micro-structure being controllable,were prepared via adjusting the concentration of spinning solution in the method of electro-spinning.The microstructure of the surfaces was characterized and the hydrophobicity of the hydrophobic surfaces mentioned above was tested.The characteristics of frosting suppression on the nano/micro-structured hydrophobic surface were studied by means of experimental comparison of the process of frosting and the performance of frosting suppression,combined with the analysis of surface fractal dimension.The results showed that although all of the nano/micro-structured hydrophobic surfaces studied were hydrophobic with their static contact angle between 139? and 152?,their hydrophobicity did not closely correlate with its frosting suppression capacity.The capacity for frosting suppression of the hydrophobic surfaces was largely dependent upon the surface characteristics and decreased with increasing fractal dimension of surface structure.

Key words: frost formation, electrospinning, nano/micro-structured, hydrophobic surface, fractal dimension
