| 摘 要： | 采用聚苯乙烯的N,N-二甲基甲酰胺溶液为原料, 通过静电喷涂的方法制备了具有微-纳米复合结构的聚苯乙烯膜. 通过调节溶液浓度, 得到了不同的结构、浸润性及吸附性的表面. 当聚苯乙烯的质量分数为5%、分子量为25000时, 得到的表面与水的接触角达到167°, 吸附力达到15 μN, 表明该膜表面具有超疏水性的同时对水滴具有很低的吸附力. 此外, 分子量的大小也对静电喷涂膜表面形貌的变化起重要的作用.

| Abstract: | Electro-spinning is widely accepted as a simple and versatile technique for producing micro- and nano-structures. Using this method, micro-nano structured polystyrene(PS) was prepaired by controlling the concentration of PS/DMF solution. At 5%(mass fraction) PS/DMF solution with PS molecular weight of 250000, the surface shows super-hydrophobicity with water contact angle of about 167° and ultra-low adhesive force to water. Furthermore, molecular weight is also important to the surface morphology of the PS film formed by electro-spinning. |
