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. |
