The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project encompasses development new coatings for face masks and filtration pieces for N95-grade respirators. The outer layer will repel the viral particles while the inner layer will adsorb moisture, making the mask comfortable for wear and assisting with social distancing compliance during the COVID-19 pandemic. The coatings are efficient in their function, provide reliable protection, and are durable. This technology is also highly promising for applications in other types of personal protective equipment such as gowns, drapes, medical aprons, as well as coatings on disposable medical devices. Apart from the medical sector, this platform has potential advantages for other goods, pharmaceutical formulations, and personal care products. This SBIR Phase I project proposes to develop innovative formulations for deposition of high-performance superhydrophobic and superhydrophilic coatings on textile surfaces for personal protective equipment. The technical innovation is fabrication of novel dendritic polymer particles with extraordinary high surface area and unusually strong adhesivity. The soft dendritic colloids are formed when a polymer solution is injected into turbulently sheared anti-solvent medium. Random stretching of the polymer solution droplets by the turbulent anti-solvent flow causes the polymer to precipitate in the form of soft dendritic structures. The critical technical hurdle is scaling manufacturing of large volumes of soft dendritic particles with fractal morphology. Technical objectives are: 1) develop an efficient liquid-based process for soft dendritic colloids fabrication on a bench scale; and 2) characterize textiles coated with the new formulations using a series of morphological, filtration efficiency, and breathability tests.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.

这项小型企业创新研究（SBIR）项目的更广泛的影响/商业潜力涵盖了开发面罩的新涂料和N95级呼吸器的过滤材料。外层将排斥病毒颗粒，而内层将吸附水分，使面罩舒适地磨损，并协助在COVID-19大流行期间的社交距离合规性。涂料的功能有效，提供可靠的保护，并且耐用。对于在其他类型的个人防护设备（例如礼服，窗帘，医疗围裙）以及一次性医疗设备上的涂料等其他类型的个人防护设备中，该技术也非常有前途。除了医疗部门，该平台还具有其他商品，药品配方和个人护理产品的潜在优势。这个SBIR I期项目提议开发创新的配方，用于在纺织品表面上为个人保护设备的高性能超疏水和超养分涂料的沉积。技术创新是制造具有非凡高表面积和异常强的粘附性的新型树突聚合物颗粒。当将聚合物溶液注入湍流剪切的抗溶剂溶质培养基中时，会形成软树突胶体。通过湍流抗可溶性流对聚合物溶液的随机拉伸导致聚合物以软树突结构的形式沉淀。关键的技术障碍是扩展具有分形形态的大量软树突颗粒的生产。技术目标是：1）开发一种有效的基于液体的过程，用于在基准尺度上制造软性树突状胶体制造； 2）用一系列形态学，过滤效率和透气性测试来表征覆盖新配方的纺织品。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估标准来通过评估来支持的。
