Low friction ice sliding interfaces were critical for ski performance optimization. Traditional fluorinated ski waxes have attracted considerable attention for enhancing the hydrophobicity, anti-wearing, and oxidation resistance of ski-ice base. However, the toxicity and complexity of the waxing process limited batch manufacturing of low-cost and non-toxic ski-ice base, what is more, the wax covering on the base wore and failed during skiing due to the friction between ski and ice. Herein, we demonstrated a novel ultra-high molecular weight polyethylene (UHMWPE) composite that could maintain a low coefficient of friction (COF) with about 0.026 for at least 160 min when skiing on the ice. Microcapsule (MS) could release liquid (liquid paraffin (LP)). The released LP further enhanced the hydrophobicity of UHMWPE’s surfaces when friction occurred, which would maintain the stability and durability of the water film, and achieved superior and long-lasting friction resistance. Compared with other microcapsules with lower hydrophobic core, microcapsules with LP performed the best in reducing the friction of ski base from 0.126 to 0.024. Meanwhile, the COF of the surface kept at about 0.02 even after 12 rapid temperature changes. The presented UHMWPE composite of encapsulated liquids showed great potential and broad application owing to its simplicity and efficiency in winter sports.

低摩擦冰滑动界面对于滑雪性能优化至关重要。传统的氟化滑雪蜡因增强滑雪冰基的疏水性、耐磨性和抗氧化性而受到广泛关注。然而，打蜡工艺的毒性和复杂性限制了低成本、无毒滑雪冰底座的批量生产，而且在滑雪过程中，由于滑雪板与冰之间的摩擦，底座上的蜡覆盖物会磨损而失效。在此，我们展示了一种新型超高分子量聚乙烯 (UHMWPE) 复合材料，当在冰上滑雪时，该复合材料可以保持约 0.026 的低摩擦系数 (COF) 至少 160 分钟。微胶囊（MS）可以释放液体（液体石蜡（LP））。释放的LP进一步增强了UHMWPE表面发生摩擦时的疏水性，从而保持水膜的稳定性和耐久性，实现优异且持久的耐摩擦性能。与其他具有较低疏水性核心的微胶囊相比，具有LP的微胶囊在将滑雪基底的摩擦力从0.126降低到0.024方面表现最好。同时，即使经过12次快速温度变化，表面的COF仍保持在0.02左右。所提出的 UHMWPE 封装液体复合材料由于其简单性和高效性在冬季运动中显示出巨大的潜力和广泛的应用。
