摘要：本发明提供了一种超疏水苯乙烯类热塑性弹性体材料的制备方法，利用可塑性SEBS作为基底，借助于良溶剂/不良溶剂诱导SEBS相分离并引入低表面能棕榈蜡和退火处理制备超疏水SEBS表面，充分利用低表面能和粗糙结构的协同作用使表面达到超疏水效果，进而抵抗水溶液中丁苯酞药物的吸附。本发明采用良溶剂/不良溶剂诱导相分离方法构建表面粗糙结构，无需昂贵设备、工艺简单、生产方便；同时引入棕榈蜡作为低表面能物质，不仅利用表面粗糙结构产生的物理疏水效应，也充分利用棕榈蜡的低表面能化学特性，二者的协同作用使抗丁苯酞效果更加优异。该材料可以有效减少药物在输液器内壁的残留、提高药物利用率。本发明还提供了包含该材料的输注类医疗器材及其在抗药物吸附中的应用。

Abstract: The present invention provides a method for preparing a superhydrophobic styrenic thermoplastic elastomer material. SEBS is used as the substrate, and phase separation is induced by a good solvent/poor solvent system. The synergistic effect of surface roughness and low surface energy chemistry endows the material with excellent superhydrophobicity, effectively resisting the adsorption of butylphthalide drugs. The material has important application value in medical infusion devices.
