SBIR Phase I: Durable Nano-Coatings with MoSi2 for Antibacterial High Wear Use

这个小型企业创新研究(SBIR)第一阶段项目旨在开发一种二硅化钼(MoSi2)纳米粒子涂层，其抗菌性能与银纳米粒子的抗菌性能相当，但成本显著降低。方法是在316L不锈钢和聚氯乙烯(PVC)等基材上沉积和优化MoSi2纳米涂层。对涂层的抗菌、耐磨、抗冲蚀性能进行了研究。该项目的更广泛/商业影响将是提供低成本解决方案以满足抗菌应用需求的潜力。考虑到社会上的细菌感染问题，在金属和聚合物基质上开发成本效益高的抗菌薄膜比目前的技术便宜得多，可能具有潜在的颠覆性，并将在医疗保健、食品制备和运送、住宅(如家庭厨房和交通部门)等方面有广泛的应用。

This Small Business Innovation Research (SBIR) Phase I project aims to develop a molybdenum disilicide (MoSi2) nanoparticle coating with antibacterial properties that are comparable to those imparted by silver nanoparticles, but with significant lower cost. The approach is to deposit and optimize MoSi2 nanoparticles coating on substrates such as 316L stainless steel and polyvinyl chloride (PVC). Antibacterial, wear and erosion performance of the coating will be studied. The broader/commercial impacts of this project will be the potential to provide low-cost solutions to meet the demands in antibacterial applications. Given the problems of bacterial infections in society, the development of cost-effective antibacterial films on metallic and polymeric substrates that are significantly cheaper than current technologies could potentially be disruptive and would have broad applications in health care, food preparation and delivery, residence such as home kitchens and the transportation sectors.
