| 中文摘要: |
| 以高密度聚乙烯(HDPE)/三元乙丙橡胶(EPDM)热塑性硫化胶(TPV)为原材料,采用金相砂纸为模板,通过模压法在TPV表面构建出超疏水表面。FE-SEM的观察表明,以金相砂纸为模板可在TPV表面获得具有较高保真度的微米级粗糙结构,模压过程中TPV表面发生的塑性变形,使得TPV表面具有比砂纸表面更为复杂的粗糙结构；润湿性测试结果表明,基于TPV的粗糙表面具有良好的疏水性,当磨料目数高于W14号砂纸时,模压后TPV表面与水的接触角可超过150°,且滚动角在10°以内,符合Cassie模型；采用W10号砂纸为模板制备的TPV表面具有最佳的超疏水性能。 |
| 英文摘要: |
| Superhydrophobic surfaces were constructed by molding method where high density polyethylene (HDPE)/ethylene propylene diene monomer (EPDM) thermoplastic vulcanizate (TPV) was used as raw material and metallographic sandpaper was used as template. Microcosmic morphology studies showed that the micron scale rough surface of TPV with high fidelity could be prepared by using the metallographic sandpaper as molding template; moreover, the micro plastic deformation in the TPV surface could be observed obviously, leading to the increase of complex surface roughness. Wettability test showed that the series roughness surfaces of TPV prepared by molding with metallographic sandpapers had strong hydrophobicity character; moreover, the contact angles were 150° or so while the rolling angles were less than 10°, which was consistent with the Cassie model. The superhydrophobic TPV surface prepared by molding with W10 type metallographic sandpaper had the best hydrophobicity. |
