The Study of the Structure and Properties of Ice/Solid Interfaces in Application to Ice Adhesion

9713544 Petrenko将研究冰与金属表面粘附的基本性质。 拉伸和剪切粘附强度的实验数据将与冰表面和冰/金属界面的纳米级性质和结构相关联，如通过使用纳米摩擦学技术（诸如原子力显微镜和其他高分辨率表面和亚表面材料探针）所确定的。 结果还将与冰表面上的液体层的性质相关，例如其厚度、电荷和电荷梯度以及其毛细管压力。 将评估所施加电场的影响。 所产生的基本知识应有助于有目的地开发防冰涂料。 ***

9713544 Petrenko The fundamental nature of the adhesion of ice to metallic surfaces will be studied. Experimental data for tensile and shear adhesion strengths will be correlated with the nano- scale properties and structure of the ice surface and the ice/metal interface, as determined by using nano- tribological techniques, such as atomic force microscopy and other high resolution surface and sub-surface materials probes. Results will also be correlated with the properties of the liquid-like layer on the surface of the ice, such as its thickness, electric charge and charge gradient, and its capillary pressure. The effects of applied electrical fields will be evaluated. The basic knowledge generated should contribute to the purposeful development of ice- phobic coatings. ***
