This Small Business Innovation Research (SBIR) Phase I project will lead to an economical wet chemical method for depositing hard and scratch resistant coatings on transparent polymer substrates. The proposed program, when successfully carried out, will solve the ubiquitous problem of transparent polymer surfaces being scratched and worn. Solution methods, which are easily scalable, have been used to develop polymer-oxide nanoparticle (hybrid) transparent coatings on transparent polymers. Such materials lack high hardness values, which can be dramatically increased by incorporating coarse oxide ceramic particles in the hybrid matrix. Based on this innovative approach to maintain transparency even with addition of a significant volume fraction of coarse particles ( 0.25 microns) to a hybrid matrix, transparent coatings will be developed on polycarbonate and acrylic substrates with excellent wear and chemical resistance. Solution methods of forming polymer nanocomposites coatings are far more economical compared to vacuum/gas phase processing (e.g., plasma polymerization), but its use has been restricted because of the poor abrasion resistance of these coatings.This novel approach will lead to exceptional wear, scratch and chemical resistance coatings, which will have a wide range of applications in the automotive, aerospace and other industries.

这个小企业创新研究（SBIR）第一阶段项目将导致一个经济的湿化学方法沉积硬和耐刮涂层透明聚合物基板。 该计划一旦成功实施，将解决透明聚合物表面被划伤和磨损的普遍问题。 溶液方法，这是很容易扩展，已被用来开发透明聚合物上的聚合物-氧化物纳米粒子（混合）透明涂层。 这样的材料缺乏高硬度值，其可以通过在混合基质中掺入粗氧化物陶瓷颗粒而显著增加。 基于这种创新的方法，即使在混合基质中添加大量体积分数的粗颗粒（0.25微米）也能保持透明度，将在聚碳酸酯和丙烯酸基材上开发出具有优异耐磨性和耐化学性的透明涂层。 形成聚合物纳米复合材料涂层的溶液方法与真空/气相处理（例如，等离子体聚合），但由于这些涂层的耐磨性差，其使用受到限制。这种新颖的方法将导致优异的耐磨性，耐刮擦性和耐化学性涂层，这将在汽车，航空航天和其他工业中具有广泛的应用。
