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

这个小企业创新研究（SBIR）二期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心，聚合物为外壳。纳米颗粒将通过一种新颖的方法以最小的介电损耗产生高介电常数的薄膜，在广谱的宿主聚合物中被夹带。为了在不失去核壳纳米粒子独特和有价值的特性的情况下扩大这一过程，将利用激光进行选择性聚合的湿化学路线，在每个金属纳米粒子上涂上聚合物外壳。该项目的更广泛/商业影响将是为纳米复合材料的发展提供高介电常数纳米颗粒的潜力，以满足未来超级电容器的能量存储需求。目前，商业上可用的超级电容器要么功率或能量密度太低，要么制造成本太高。该项目有望以经济有效的方式提供高能量和功率密度，从而实现超高能量存储电容器的制造。

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.
