The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is to develop a sustainable, scalable, and high-performance alternative to natural leather fabric. Leather is one of the most widely used fabric materials in the world, with over two billion square yards produced through animal agriculture every year. The production of animal-derived leather emits greenhouse gases and pollution from the toxic chemicals used to process, tan, and dye animal hides. Current synthetic alternatives are made of non-renewable polymers such as polyurethane and polyvinyl chloride, contributing to petrochemical consumption and plastic pollution. This project aims to develop an alternative leather material that is 100% bio-based and environmentally friendly, and that meets industry requirements for mechanical, physical, and aesthetic properties. By engineering composite materials with superior performance and quality, this technology has the potential to reduce the environmental impact of leather-utilizing industries such as fashion apparel, footwear, furniture, and automotives. This SBIR Phase I project proposes to use a biomimetic approach to developing high-performance materials that replicate the collagen microstructure and properties of natural leather. Current synthetic alternatives contain petroleum-derived binding or coating agents. This project aims to meet objectives to 1) develop novel compositional and processing methods to produce 100% bio-based crosslinked materials, 2) systematically characterize the mechanical, physical, and surface properties to evaluate performance features, and 3) demonstrate reproducibility and tunability in alignment with industry metrics. The proposed technology leverages innovation in chemical crosslinking to produce high-strength, ultra-durable, soft-to-the-touch materials for the next generation of sustainable fabrics.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.

这个小企业创新研究（SBIR）项目更广泛的影响/商业潜力是开发一种可持续、可扩展且高性能的天然皮革织物替代品。皮革是世界上使用最广泛的织物材料之一，每年通过畜牧业生产超过20亿平方码。动物皮革的生产会排放温室气体，以及用于加工、鞣制和染色动物皮革的有毒化学品造成的污染。目前的合成替代品是由聚氨酯和聚氯乙烯等不可再生聚合物制成的，这导致了石化消费和塑料污染。该项目旨在开发一种替代皮革材料，该材料是100%生物基和环境友好型的，并满足行业对机械，物理和美学性能的要求。通过设计具有上级性能和质量的复合材料，该技术有可能减少时尚服装、鞋类、家具和汽车等皮革使用行业对环境的影响。 SBIR第一阶段项目提出使用仿生方法开发高性能材料，复制天然皮革的胶原蛋白微观结构和性能。目前的合成替代品含有石油衍生的粘合剂或涂层剂。该项目旨在实现以下目标：1）开发新的成分和加工方法，以生产100%生物基交联材料，2）系统地表征机械，物理和表面特性，以评估性能特征，3）证明可重现性和可调性与行业指标一致。该技术利用化学交联技术的创新，为下一代可持续织物生产高强度、超耐用、触感柔软的材料。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。
