SBIR Phase II: Affordable point-of-use water disinfection through mass-produced nano-silver embedded paper filters

这个小企业创新研究（SBIR）第二阶段项目的更广泛影响集中在研究和开发用于低成本使用点水净化的抗菌纳米颗粒滤纸。 拟议的项目将开发一种抗菌纸净水器，包装像咖啡过滤器，通过零售渠道分销。该项目将为世界各地的许多社区提供安全用水。该SBIR第二阶段项目将推进使用大型造纸机和类似卷到卷工艺的工艺开发，以制造低成本的纳米金属功能化材料，如纳米银滤纸。第二阶段的目标包括：（i）优化工艺以降低材料和其他成本，增加流速，并保持高质量性能，（ii）通过改进配方和正式确定产品保质期来减轻水化学和微生物的变化，从而证明过滤系统更稳健，（iii）证明在试验和工业速度和输出水平下的生产，同时验证非破坏性质量控制程序，以及（iv）整合第三方产品安全认证测试。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impacts of this Small Business Innovation Research (SBIR) Phase II project focuses on the research and development of an antimicrobial nanoparticle filter paper for low-cost point-of-use water purification. The proposed project will develop an antimicrobial paper water purifier, packaged like a coffee filter, to be distributed through retail channels. This project will offer safe water to many communities throughout the world. This SBIR Phase II project will advance the development of a process using large-scale paper machinery and similar reel-to-reel processes to manufacture low-cost nano-metal functionalized materials, such as nanosilver filter paper. Phase II objectives include: (i) optimize the process to reduce materials and other costs, increase flow rate, and maintain high-quality performance, (ii) demonstrate a more robust filter system by mitigation of water chemical and microbiology variability through improved formulation and formal determination of product shelf-life, (iii) demonstrate production at pilot and industrial speeds and output levels, while validating a non-destructive quality control program, and (iv) integrate third-party product safety certification 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.
