The broader impact and commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to develop a new environmentally sustainable material for diapers and incontinence products. In the US, 25 million adults suffer from urinary incontinence, generating up to 1.5 million kilograms of problematic material for landfills. The proposed material will be manufactured using cheap, and renewable raw materials, improving the environmental impact of managing this condition and enabling high quality of life for its users. This Small Business Innovation Research (SBIR) Phase I project proposes to develop a new superabsorbent polymer (SAP). In the first phase of research, this project will identify design parameters based on polymer architecture, charge density, and gel fraction for a SAP that meets specifications regarding absorbency under load (AUL), centrifuge retention capacity (CRC), and kinetics of absorption. The project will validate the safety and biodegradability in simulated composting conditions. Finally, the project will explore protocols for manufacturing at scale.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.

该小企业创新研究 (SBIR) 第一阶段项目的更广泛影响和商业潜力是为尿布和失禁产品开发一种新的环境可持续材料。在美国，有 2500 万成年人患有尿失禁，产生了多达 150 万公斤的有问题的材料进行垃圾填埋。 拟议的材料将使用廉价、可再生的原材料制造，从而改善管理这种情况对环境的影响，并为其用户提供高质量的生活。该小型企业创新研究 (SBIR) 第一阶段项目建议开发一种新型高吸水性聚合物 (SAP)。在研究的第一阶段，该项目将根据聚合物结构、电荷密度和凝胶分数确定 SAP 的设计参数，以满足负载下吸收率 (AUL)、离心保留能力 (CRC) 和吸收动力学方面的规范。该项目将验证模拟堆肥条件下的安全性和生物降解性。最后，该项目将探索大规模制造的协议。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。
