A versatile, convenient, and cost-effective method that can be used for grafting anti-icing materials onto different surfaces is highly desirable. Based on mussel-inspired chemistry, the anti-icing coating with extremely low ice adhesion is enabled by constructing a self-sustainable lubricating layer, achieved via modifying solid substrates with a highly hydrophilic conjugate of poly(acrylic acid)-dopamine. Both unfreezable and freezable water remain liquidlike at subzero conditions and synergistically fulfill the role of lubrication for reducing the ice adhesion. The anti-icing coatings show excellent stability in harsh environments and durability after the cross-linking. More importantly, this coating can be applied to various substrates and is of great promise for practical applications.
一种通用、便捷且经济高效的方法，可用于将防冰材料接枝到不同表面，这是非常令人期待的。基于贻贝启发化学，通过用聚（丙烯酸）-多巴胺的高亲水性共轭物修饰固体基材，构建自维持润滑层，从而实现具有极低冰附着力的防冰涂层。在零下条件下，不可冻结水和可冻结水均保持类液态，并协同发挥润滑作用以降低冰附着力。该防冰涂层在恶劣环境中表现出优异的稳定性，交联后具有耐久性。更重要的是，这种涂层可应用于各种基材，在实际应用中具有巨大潜力。
