生物相容性和抗菌表面的构建变得越来越重要。然而，大多数现有技术需要多步骤程序、严格的条件和特定的底物。我们在这里提出了一种简便的方法，可以在环境条件下在几乎任何基材上创建生物相容性和抗菌表面。该策略基于从二甲苯和癸醇的溶剂混合物中铸造高度粘附的弹性体苯乙烯-b-(乙烯-共-丁烯)-b-苯乙烯，其中癸醇既充当聚合物沉淀剂以引发相分离，又充当液体模板以稳定超疏水结构。稳定耐用的超疏水表面表现出良好的生物相容性和抗菌性能。
The construction of biocompatible and antibacterial surfaces is becoming increasingly important. However, most of the existing techniques require multi-step procedures, stringent conditions and specific substrates. We present here a facile method to create a biocompatible and antibacterial surface on virtually any substrate under ambient conditions. The strategy is based on casting a highly adherent elastomer, styrene-b-(ethylene-co-butylene)-b-styrene, from a solvent mixture of xylene and decanol, in which decanol acts as both a polymer precipitator to induce phase separation and a liquid template to stabilize the superhydrophobic structure. The stable and durable superhydrophobic surface shows good biocompatibility and antibacterial properties.
