The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to develop coatings for plastics, with applications from sanitation to automotive displays. Few surface coatings on plastics can resist fouling of bacteria and mineral deposits while also achieving both liquid- and sludge-repellency. This project will develop a slippery surface coating that repels liquid, sludge, bacteria, and mineral deposits on common plastics. This Small Business Innovation Research Phase II project will advance translation of liquid-entrenched smooth surface (LESS) coatings that can be directly applied to various plastics. Functionalizing plastics with mechanically durable surface coatings is challenging owing to the lack of reactive surface chemistry. LESS demonstrates excellent liquid- and sludge-repellency with over 95% reduction in bacteria accumulation and mineral deposits compared to untreated surfaces. This project will investigate the optimal formulation and coating parameters to enhance interfacial bonding strength of LESS onto plastics through combined molecular dynamic simulations and experimental characterizations. The newly developed LESS-on-plastics coatings will be systematically evaluated for their mechanical and UV durability, liquid- and sludge-repellency as well as the anti-bacterial and anti-scaling functions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小企业创新研究（SBIR）第二阶段项目的更广泛的影响/商业潜力是开发塑料涂料，从卫生到汽车显示器的应用。很少有塑料表面涂层可以抵抗细菌和矿物质沉积物的污染，同时还实现液体和污泥排斥性。该项目将开发一种光滑的表面涂层，可以排斥普通塑料上的液体，污泥，细菌和矿物沉积物。这个小型企业创新研究第二阶段项目将推进可直接应用于各种塑料的液体嵌入式光滑表面（LESS）涂层的转化。由于缺乏反应性表面化学，用机械耐用的表面涂层官能化塑料具有挑战性。与未经处理的表面相比，LESS具有出色的液体和污泥排斥性，细菌积累和矿物质沉积减少了95%以上。本项目将通过分子动力学模拟和实验表征相结合，研究最佳配方和涂层参数，以提高LESS与塑料的界面结合强度。新开发的LESS-on-plastic涂层将对其机械和紫外线耐久性、拒液和污泥性能以及抗菌和防垢功能进行系统评估。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
