Ice accretion may cause serious safety risk and huge economic loss for outdoor facilities. Herein, we report a waterborne polymeric coating based on a copolymer network of methacrylic acid (MAA), acrylamide (AM), -2-hydroxyethyl acrylamide (HEAA), and methoxypolyethylene glycol (MPEG) with free polyethylene glycol (PEG) dispersed in it. Owing to the good compatibility of free PEG chains and the PEG side chains of the copolymer, the hydrogen bonding between acrylic copolymer and PEG, the free PEG chains can well be trapped in the network with some segments out of the mesh as short PEG chains are grafted on the coating surface, so that the surface has liquid-like properties. Water droplets can readily slip off on the coating surface with a small sliding angle (<30°). Particularly, the surface can hold the properties for a long duration upon water flushing, cycle of wetting-drying, and salt spraying tests. The polymer coating can find application in icing prevention and removal.

用于防冰和除冰的聚合物涂层

积冰可能会给户外设施造成严重的安全隐患和巨大的经济损失。在此，我们报道了一种基于甲基丙烯酸（MAA）、丙烯酰胺（AM）、-2-羟乙基丙烯酰胺（HEAA）和甲氧基聚乙二醇（MPEG）的共聚物网络的水性聚合物涂料，其中分散有游离聚乙二醇（PEG） 。由于游离 PEG 链与共聚物的 PEG 侧链相容性好，丙烯酸类共聚物与 PEG 之间存在氢键，游离 PEG 链可以很好地陷入网络中，而部分链段则脱离了网状结构，因为短 PEG 链接枝在涂层表面，使表面具有液体般的性能。水滴很容易在涂层表面以较小的滑动角（<30°）滑落。特别是在水冲洗、干湿循环和盐雾测试中，表面可以长时间保持性能。聚合物涂层可应用于防冰和除冰。
