This Small Business Innovation Research Phase I project seeks to reduce the cost and complexity of incorporating energy-saving phase change materials (PCMs) into end-use products by developing a new class of form-stable PCM-modified resins that contain a unique reactive-polyolefin component. Importantly, the development of new PCMs for the passive thermal regulation of electric vehicle (EV) batteries has the potential to increase EV safety, range, and affordability, representing an addressable market currently valued at $87m and that is growing at 20% per year. Validation of these advantages should significantly benefit society by increasing electric vehicle performance and reducing the frequency of expensive battery replacement, thus increasing the adoption of energy efficient vehicles and reducing green-house gas emissions. This project can also result in an increase in the penetration of energy efficient PCM technology in additional markets worth a combined $370m, including building materials, textiles, electronics, and packaging, which can have a large positive economic impact on society. Finally, successful realization of the goals of this SBIR Phase I program will further enable scientific / technological understanding of PCMs that are based on organic materials.The intellectual merit of this project is the validation of a new paradigm for a bottoms-up approach to the design, production, and optimization of structurally-well-characterized reactive polyolefins of tunable molecular weight and narrow polydispersity that possess superior performance and stability characteristics as organic phase change materials (PCMs) for waste heat management as compared to conventional paraffin-based PCMs that have remained virtually unchanged for the past half century. To achieve this goal, reactive polyolefins that are the best candidates for commercialization will be identified through optimization of molecular structure, stereochemical tacticity, and the temperature and kinetics of main-chain and side-chain phase transitions. Reaction variables will also be optimized to provide the highest yields of reactive polyolefins under industrially-relevant and scalable process conditions. The development of PCM-modified thermoset resins based on reactive polyolefins will provide access to commercial waste heat management applications that employ physical constructs obtained from casting or injection molding and should benefit from lower production costs, a wider range of applications, and greater long-term stability.

该小型企业创新研究第一阶段项目旨在通过开发一种新型的含有独特反应性聚烯烃成分的形状稳定的 PCM 改性树脂，降低将节能相变材料 (PCM) 融入最终用途产品的成本和复杂性。重要的是，开发用于电动汽车 (EV) 电池被动热调节的新型 PCM 有可能提高电动汽车的安全性、续航里程和经济性，目前的潜在市场价值为 8700 万美元，并且每年以 20% 的速度增长。这些优势的验证应该通过提高电动汽车性能和减少昂贵的电池更换频率来显着造福社会，从而增加节能汽车的采用并减少温室气体排放。该项目还可以提高节能 PCM 技术在价值总计 3.7 亿美元的其他市场的渗透率，包括建筑材料、纺织品、电子产品和包装，这可以对社会产生巨大的积极经济影响。最后，成功实现该SBIR第一阶段计划的目标将进一步促进对基于有机材料的相变材料的科学/技术理解。该项目的智力价值是验证了一种自下而上的方法的新范式，用于设计、生产和优化结构良好的反应性聚烯烃，该聚烯烃具有可调分子量和窄多分散性，具有作为有机相变材料的优异性能和稳定性特征 相变材料（PCM）用于废热管理，与传统的石蜡基相变材料相比，传统的石蜡基相变材料在过去的半个世纪中几乎没有变化。为了实现这一目标，将通过优化分子结构、立体化学立构规整度以及主链和侧链相变的温度和动力学来确定最适合商业化的反应性聚烯烃。反应变量也将被优化，以在工业相关和可扩展的工艺条件下提供最高产量的反应性聚烯烃。基于反应性聚烯烃的 PCM 改性热固性树脂的开发将为商业废热管理应用提供机会，这些应用采用铸造或注塑成型获得的物理结构，并应受益于更低的生产成本、更广泛的应用和更高的长期稳定性。
