SBIR Phase II: Metamaterials for Giant Dielectrics and Energy Storage Solutions

这个小企业创新研究（SBIR）第二阶段项目旨在开发一种核-壳纳米粒子结构，以金属纳米粒子为高电容核，聚合物为壳。 纳米粒子将通过一种新的方法被夹带在一个广泛的主体聚合物中，以产生具有最小介电损耗的高介电常数薄膜。 为了在不损失核-壳纳米颗粒的独特和有价值的性质的情况下扩大该过程，将利用用于选择性聚合的激光的湿化学路线来用聚合物壳涂覆每个金属纳米颗粒。 该项目的更广泛/商业影响将是为纳米复合材料的开发提供高介电常数纳米颗粒的潜力，以满足超级电容器未来的储能需求。 目前，市售的超级电容器要么具有太低的功率或能量密度，要么制造起来太昂贵。 该项目有望通过以具有成本效益的方式提供高能量和功率密度来制造超高储能电容器。

This Small Business Innovation Research (SBIR) Phase II project aims to develop a core-shell nanoparticle architecture with metal nanoparticles as the high capacitance core, and polymers as the shell. The nanoparticles will be entrained in a broad spectrum of host polymers via a novel approach to produce high dielectric-constant films with minimum dielectric loss. To scale up this process without losing the unique and valuable properties of core-shell nanoparticles, a wet chemistry route with laser for selective polymerization will be utilized to coat each metal nanoparticle with a polymeric shell. The broader/commercial impact of this project will be the potential to provide high-dielectric constant nanoparticles for the development of nanocomposite to meet future energy storage needs of supercapacitors. Currently, commercially available supercapacitors either have too low power or energy density or are too expensive to manufacture. This project is expected to enable the fabrication of ultra high energy storage capacitors by providing high energy and power density in a cost-effective manner.
