Icephobic coatings have applications in many industries to protect surfaces from deterioration and avoid catastrophic incidents. In this work, we report a new strategy to prepare amphiphilic siloxane-glycidyl carbamate coatings (AmpSiGC) coatings with anti-icing property. Polydimethyl siloxane (PDMS) and poly(ethylene glycol) (PEG) provided amphiphilicity for the AmpSiGC coatings. The designed experiment considered several factors: molecular weight of the surface-modifying polymers and their amount in the coating system. Although amphiphilic coatings have demonstrated promising results as marine coatings, investigations on their icephobic applications have been limited. This work discusses three aspects of the developed AmpSiGC systems: (1) preparation of the incorporated ingredients and their characterization by Fourier transform infrared spectroscopy (FTIR); (2) surface characterization of coatings via ATR (attenuated total reflectance)-FTIR, X-ray photoelectron spectroscopy (XPS), and atomic force microscopy (AFM); and (3) ice-adhesion, electrochemical impedance spectroscopy (EIS), and mechanical property evaluations. Overall, the surface analysis indicated the presence of both hydrophobic and hydrophilic domains and most of the coatings demonstrated promising performance for anti-icing applications with desirable barrier and mechanical properties in comparison to controls.

憎冰涂层在许多行业中都有应用，可保护表面不致变质并避免发生灾难性事件。在这项工作中，我们报告了一种制备具有防冰性能的两亲性硅氧烷-缩水甘油基氨基甲酸酯涂料（AmpSiGC）涂层的新策略。聚二甲基硅氧烷（PDMS）和聚（乙二醇）（PEG）为AmpSiGC涂层提供了两亲性。设计的实验考虑了以下几个因素：表面改性聚合物的分子量及其在涂料体系中的含量。尽管两亲性涂层已显示出可作为海洋涂层的良好前景，但对其憎冰性应用的研究仍然有限。这项工作讨论了已开发的AmpSiGC系统的三个方面：（1）掺入成分的制备及其通过傅里叶变换红外光谱（FTIR）的表征；（2）通过ATR（衰减全反射）-FTIR，X射线光电子能谱（XPS）和原子力显微镜（AFM）表征涂层的表面特性；（3）冰的附着力，电化学阻抗谱（EIS）和机械性能评估。总的来说，表面分析表明疏水域和亲水域均存在，并且大多数涂料与对照相比，具有良好的阻隔性和机械性能，在防冰应用中表现出令人鼓舞的性能。电化学阻抗谱（EIS）和机械性能评估。总的来说，表面分析表明疏水域和亲水域均存在，并且大多数涂料与对照相比，具有良好的阻隔性和机械性能，在防冰应用中表现出令人鼓舞的性能。电化学阻抗谱（EIS）和机械性能评估。总的来说，表面分析表明疏水域和亲水域均存在，并且大多数涂料与对照相比，具有良好的阻隔性和机械性能，在防冰应用中表现出令人鼓舞的性能。
