摘　　要：润滑剂灌注表面(LIS)能够减少来自不同来源的污染(包括细菌、冰和水垢).然而,润滑剂的液体特性经常导致这类表面在恶劣环境中流失,从而无法防止污垢的沉积.本文报道了一种相变润滑剂灌注的表面,实现了长期高效抗水垢.当温度在润滑剂的熔点以下时,润滑剂为固态,展示出了高的稳定性.当温度在润滑剂的熔点以上时,液态润滑剂利用其光滑的表面形貌和水垢黏附的降低,实现了抗水垢.本文对于处理实际应用中结垢问题,特别是在温度变化场景下的结垢问题,提供了一种可行方法.The use of lubricant-infused surfaces(LIS)presents a highly promising approach to mitigating contamination from various sources,including bacteria,ice,and scale.However,these lubricants’natural liquid characteristics frequently cause them to run out in adverse environments,which results in a failure to prevent fouling.Here,we report the sustainable anti-scaling performance of a phase-change lubricant-infused surface(PCLIS).The increased resistance is ascribed to a high degree of stability in the solid state at temperatures below PCL’s melting point(T<Tm).Furthermore,the anti-scaling capability comes from its smooth morphology and reduced scale adhesion in liquid state(T>Tm).As a result,this work offers a viable method to deal with scaling problems in real-world applications,especially those that involve temperature changes.
