Abstract：
In this paper, a new method involving a wear-resistant and reusable template is proposed for the preparation of high-mechanical-strength superhydrophobic polymer film based on wire electrical discharge machining (WEDM). A solid-liquid-contact-angle simulation model was established to obtain surface-texture types and sizes that may achieve superhydrophobicity. The experimental results from template preparation show that there is good agreement between the simulation and experimental results for the contact angle. The maximum contact angle on the template can reach 155.3° given the appropriate triangular surface texture and WEDM rough machining. Besides, the prepared superhydrophobic template exhibits good wear resistance and reusability. PDMS superhydrophobic polymer films were prepared by the template method, and their properties were tested. The experimental results from the preparation of superhydrophobic polymer films show that the maximum contact angle of the polymer films can be up to 154.8° and that these films have good self-cleaning and anti-icing properties, wear resistance, bending resistance, and ductility.
摘要：
在本文中,提出了一种涉及耐磨和可重复使用的模板的新方法，用于基于电火花线切割加工（WEDM）制备高机械强度的超疏水聚合物膜。建立了固液接触角模拟模型，以获得可以实现超疏水性的表面纹理类型和尺寸。模板制备的实验结果表明，接触角的模拟结果与实验结果具有良好的一致性。在适当的三角形表面纹理和电火花线切割粗加工的情况下，模板上的最大接触角可以达到155.3°。此外,制备的超疏水模板具有良好的耐磨性和可重复使用性。采用模板法制备了PDMS超疏水聚合物薄膜,并对其性能进行了测试。制备超疏水聚合物薄膜的实验结果表明，聚合物薄膜的最大接触角可达154.8°，并且这些薄膜具有良好的自清洁和防冰性能，耐磨性，耐弯曲性，和延展性。
