通过转录斥水植物叶片的微观结构和化学处理相结合的方法，在生物可降解聚合物表面制备了超疏水表面。选择天南星属植物叶作为超疏水表面的制备材料，因为该植物叶具有易于处理的微观结构。采用复型法将显微图案转录到聚己内酯（PCL）片上，再用丙酮/甲醇混合溶液浸泡处理。所得具有显微镜下的条纹图案的PCL显示出148°的高水接触角，并且还显示出对丝状真菌的抗菌性能。
Super-hydrophobic surface has been prepared onto biodegradable polymer by a combination of transcribing microscopic structure of a water-repellent leaf and a chemical treatment. An aroid leaf has been chosen for the preparation of the super-hydrophobic surface since the leaf has concavity microscopic structure, which is easy to handle for a material use. The microscopic pattern was transcribed onto poly(ε-caprolactone) (PCL) sheet by using replica method, then it was further treated by soaking in a mixture of acetone/methanol solution. The resultant PCL having the microscopic concavity pattern showed high water contact angle of 148° and also showed antibacterial property for filamentous fungi.
