摘　　要：利用纳米流控系统特殊的能量吸收/转换特性,设计了一种新型超弹吸能鞋垫。该超弹吸能鞋垫内填充了蜂窝状骨架,蜂窝状骨架内包覆有由疏水性纳米多孔材料和功能流体组成的纳米流控能量吸收/转换系统。介绍了新型超弹吸能鞋垫的减震机理,当鞋垫受到外界冲击时,随着外界压力对鞋垫的加载和卸载,非浸润性液体进出纳米多孔材料的疏水微孔中,实现能量的存储、释放和消耗,从而使得鞋垫对于人体足部的反冲力减小。新型超弹吸能鞋垫的吸能层能够通过自身体积变化缓冲起跳落下时的冲击力,在提高鞋垫的减震性能及舒适度的同时减小运动人员下肢运动损伤风险。A new super-elastic energy-absorbing insole was designed based on the special energy absorption/conversion characteristics of the nanofluidic system.The super-elastic energy-absorbi ng insole was filled with a honeycomb skeleton,and the honeycomb skeleton was covered with a nano-fluidic energy absorption/conversion system composed of a hydrophobic nano-porous material and a functional fluid.The shock absorption mechanism of a new type of super-elastic energy-absorbing insole was introduced.When the insole is subjected to external impact,as external pressure loads and unloads the insole,non-invasive liquid enters and exits the hydrophobic micropores of the nanoporous material,thus achieving the energy storage,release and consumption,so that the impulse of the insole on the human foot is reduced.The energy-absorbing layer of the new super-elastic energy-absorbing insole can buffer the impact force when taking off and falling through its own volume change,which can improve the shock absorption performance and comfort of the insole and reduce the risk of lower limb sports injuries.
