| 摘要: |
| 仿猪笼草结构的灌注液体型超润滑涂层(SLIPS)因具有优异的自清洁防污性能备受关注，但目前存在制备工艺复杂、成本较高、不适宜大规模制备等问题，影响了该技术的实际应用。针对这一问题，利用火焰喷涂技术制备SLIPS表面的技术工艺，成功在不锈钢表面制备了基于纳米二氧化钛的SLIPS涂层，并研究了涂层结构及性能。利用SEM分析了涂层的表面形貌和微观结构；利用接触角测量仪研究了涂层的浸润性能；通过藻类贴附试验评价了涂层的防污性能。结果表明：所制备涂层表面接触角达到118.01°，滚动角达到4.54°，呈超润滑性能，对海洋小球藻附着率降低了98.56%。文中研究为制备低成本、大规模SLIPS涂层提供了一种可行的思路。 |

| Abstract: |
| Slippery liquid infused porous surfaces (SLIPS) have been extensively studied, which are a type of nepenthes pitcher-inspired materials with excellent self-cleaning and antifouling performance. However, their practical usage is limited by factors such as complicated preparation process, high cost and inconvienence for large-scale preparation. Here a facile manufacturing process was successively established to prepare nano-titanium dioxide-based SLIPS coating on the surface of stainless steel by flame spraying technology. The microstructure and antifouling properties of the prepared SLIPS coating was analyzed. The morphology and microstructure of the coating were examined by scanning electron microscope. The wettability of the coating was analyzed by contact angle instrument. The anti-biofouling performance was evaluated by the settlement of a typical marine biofouling organism Chlorella vulgaris. Results show that the surface contact angle and sliding angle of water droplets on the prepared SLIPS coating reach 118.01° and 4.54°, respectively. The adhesion rate of marine Chlorella is significantly reduced by 98.56%. It provides a feasible approach for the fabrication of low-cost and large-scale SLIPS coatings. |
