SBIR Phase I: Development of Novel Nanofillers for Tire Innerliners Based on an Advanced Manufacturing Process of Organically Functionalized Layered Double Hydroxides (LDHs)

这项小型企业创新研究（SBIR）第一阶段项目旨在开发一种具有成本效益和环境友好的工艺来制备有机功能化层状双氢氧化物（organoLDHs）。这种有机oldhs具有二维纳米血小板样形态，并且与有机聚合物具有良好的相容性。在这个项目中，有机oldhs将被研究作为轮胎内层的高性能添加剂，内层是充气轮胎的最内层，用于保持内部空气压力。添加有机oldhs，即使是少量的，也有望显著提高轮胎内层的充气压力保持（气体屏障）性能。该项目的更广泛/商业影响将是有可能在轮胎行业创造一类具有巨大市场潜力的新型添加剂产品。这些产品提供的价值包括：(1)更好的轮胎性能，包括增强的充气压力保持，更好的轮胎耐久性和减少滚动阻力；(2)帮助轮胎和汽车制造商满足汽车燃油经济性和温室气体排放方面具有挑战性的法规；(3)潜在的制造成本节约。这项技术的潜在市场规模约为1亿美元。

This Small Business Innovation Research (SBIR) Phase I project aims to develop a cost-effective and environmentally-friendly process to prepare organically functionalized layered double hydroxides (organoLDHs). Such organoLDHs feature a two-dimensional nano-platelet like morphology and are tuned to have good compatibility with organic polymers. In this project, organoLDHs will be studied as high-performance additives for tire innerliners, the inner-most layer of a pneumatic tire that holds the internal air pressure. The addition of organoLDHs, even in small amounts, is expected to significantly enhance the inflation pressure retention (gas barrier) properties of tire innerliners. The broader/commercial impact of this project will be the potential to create a new class of additive products with great market potential in the tire industry. The values such products provide include (1) better tire performance, including enhanced inflation pressure retention, better tire durability and reduced rolling resistance; (2) helping tire and automobile manufacturers meet challenging regulations on vehicle fuel economy and greenhouse gas emissions; and (3) potential savings on manufacturing cost. The potential addressable market size of this technology is about $100 million.
