摘要

采用模板法制备了具有微纳米复合结构的聚苯乙烯接枝聚氧乙烯（PS-g-PEO）共聚物膜.将其与滴涂法制备的平滑膜进行比较，考察了PEO含量、表面形貌对共聚物膜表面浸润性产生的影响.将制备的膜进行退火及水浸泡处理后测其接触角变化.退火和水浸泡处理可以使共聚物膜表面浸润性发生可逆改变，退火后共聚物膜表面接触角增大，水浸泡后接触角减小.其中退火后的PEO含量为40.9%的共聚物平滑膜进行水浸泡处理后，膜表面接触角由65.1°减小到53.3°，而对应的共聚物粗糙膜表面接触角由150.0°减小到60.9°，实现了超疏水到亲水的转变.不同处理条件下PEO链段聚集状态不同，退火及水浸泡处理使PEO链段发生翻转，导致膜表面浸润性发生可逆改变.

Abstract

Polystyrene grafted poly (ethylene oxide) (PS-g-PEO) copolymer film with micro-nano-composite structure is prepared by template. Comparing with the smooth surface prepared by dispensed, the PEO content, the surface morphology of the impact of copolymer film surface wettability are investigated. The contact angle changes of the film are measured with after annealing and water soaking treatment. Annealing and water soaking can make copolymer film surface wettability reversible changed. Copolymer film surface contact angles increased after annealing and decreased after water soaking. Among them the annealing PEO content of 40.9% copolymer smooth surface after water soaking, the film surface contact angle decreased from 65.1º to 53.3º, while the corresponding copolymer film rough surface contact angle decreased from 150.0º to 60.9º, which means the film transformed from superhydrophobic to hydrophilic. PEO chains in different processing conditions have different aggregation. Annealing and water soaking can make the PEO chain segment eversion in the macromolecular chains, lead to reversible change of the film surface wettability.
