| 中文摘要: |
| 目的：应用仿生摩擦学原理制备皮肤减阻材料，并分析其减阻性能。方法：制备水减阻材料、油减阻材料、仿鲨鱼黏液减阻材料，进行包裹物漂浮测试和运动员泳池测试，分析减阻材料性能。结果：漂浮实验表明，与对照组相比，涂覆水减阻材料、油减阻材料和仿鲨鱼黏液减阻材料均有明显减阻效果（P＜0.01），仿鲨鱼黏液材料减阻效果最佳。结论：利用仿生摩擦学原理，应用聚乙烯吡咯烷酮（PVP）、聚乙烯醇（PVA）和聚丙烯酰胺（PAM）等超高分子量聚合物制备的仿鲨鱼黏液减阻材料有明显减阻效果。 |

| Objective: To make biomimetic skin drag reduction material and analyze its properties. Methods: The water drag reduction material, the oil drag reduction material, and the shark like mucus drag reduction material were prepared. And then floating tests and athlete pool tests were conducted to analyze the properties of different drag reduction materials. Results: The floating tests of different drag reduction materials showed that compared with the control group, the coated water drag reduction material, oil drag reduction material and shark like mucus drag reduction material, all had obvious drag reduction effect (P＜0.01), among which the shark like mucus drag reduction material was the best. Conclusions: Shark like mucus drag reduction material made of ultra-high molecular polymers such as PVP, PVA and PAM based on principles of biomimetic tribology has obvious drag-reduction effect, which helps to improve swimming performance. |
