This Small Business Innovation Research Phase II project aims to develop a low cost yet durable ice-release coating to mitigate icing-related problems encountered by air transportation, power transmission, wind energy and commercial refrigeration industries. In Phase I the first laboratory test for ice adhesion using a commercial instrument led to rapid screening of ice release coating candidates. A new theory for rigid adherent removal in shear from hybrid elastomers led to a study of ice adhesion, that is, ice as a rigid adherent. Guided by the new model and practical experience gained from laboratory tests, a new coating system was identified from which ice could be removed easily and with low force. Feasibility was demonstrated for being able to produce a durable, low cost, ice-release coating with commercially available engineering materials. This was a major success that achieved the main objective of Phase I R&D. In Phase II, the main technical objectives are to decrease peak removal force and retain low cost components and easy processing. The broader impact/commercial potential of this project include generation of low cost, durable ice-release coatings and related products. These new materials will greatly reduce icing problems and enhance the safety of operations in the aerospace, energy, and refrigeration industries. More specifically, coatings developed in this project will be used as an alternative to the following: environmentally problematic de-icing fluids, energy inefficient electrical heating, and high cost but poor mechanically durable deicing coatings.

这个小型企业创新研究第二阶段项目旨在开发一种低成本但耐用的冰释放涂层，以减轻航空运输，电力传输，风能和商业制冷行业遇到的结冰相关问题。在第一阶段，使用商业仪器进行的第一次冰附着力实验室测试导致了对冰释放涂层候选物的快速筛选。一个新的理论，刚性粘附去除剪切从混合弹性体导致的研究冰的粘附，即冰作为一个刚性粘附。在新模型和从实验室试验中获得的实践经验的指导下，确定了一种新的涂层系统，可以很容易地用很小的力去除冰。证明了能够用市售工程材料生产耐用、低成本的冰释放涂层的可行性。这是一个重大的成功，实现了第一阶段研发的主要目标。在第二阶段，主要的技术目标是降低峰值移除力并保留低成本部件和易于加工。该项目更广泛的影响/商业潜力包括生产低成本，耐用的冰释放涂层和相关产品。这些新材料将大大减少结冰问题，提高航空航天、能源和制冷行业的操作安全性。更具体地说，本项目中开发的涂层将用作以下方面的替代品：有环境问题的除冰液，能源效率低下的电加热，以及成本高但机械耐用性差的除冰涂层。
