摘　　要：植物人厌槐叶萍由于其表面特殊的"毛发"结构而具有水下保持空气层的能力,试验探讨多层植绒以及仿人厌槐叶萍的亲水尖端对水下空气层保持性能的影响。研究发现,双层植绒可减慢表面气泡流失,提高织物表面气液界面的稳定性;而三层植绒并无进一步减缓气泡流失的作用。在三层植绒样品上进行亲水尖端的仿生试验,发现采用沾取法亲水点施加,可以得到密度、面积比与人厌槐叶萍表面亲水端可比拟的点状亲水结构。试验证明,亲水尖端的存在有利于提高气液界面的稳定性。The plant Salvinia molesta can retain the air layer in water due to its complex hairy surface. The influences of multi-layer flocking structures and hydrophilic tips on the air retention property are investigated. The results show that the double-layer flocking structures can enhance the stability of air-water interface by decreasing the air bubble loss. Compared with double-layer structures, triple-layer structures do not show better performance. The bionic test of hydrophilic tip on triple-layer flocking sample is carried out. A point hydrophilic structure of flocking sample surface with hydrophilic tips is obtained by dipping method, which is comparable with Salvinia molesta surface in density and area ratio. It is proved that the hydrophilic tips can enhance the stability of air-water interface.
