Applied Quantum Materials Inc. - the industrial partner of this project - has recently developed a novel**synthesis method to engineer nanoparticles with unique optical properties. These nanoparticles have a variety**of potential commercial applications, however potential customers require the particles to be immobilized in a**polymer matrix to form a bulk optical material.**The purpose of the proposed work is to develop a method to embed these materials in a polymer matrix. It can**be challenging to achieve good mixing and to preserve the optical properties of the nanomaterials. It is very**important to achieve good dispersion of the nanomaterials, and also to ensure that the mixing conditions do not**lead to degradation of the nanoparticles. In this work we will develop a process based on melt-mixing and**compare the properties of composites formed under conditions. We will characterize the optical, thermal, and**mechanical properties of the resulting composites, and determine the minimum concentration of nanoparticles**required to achieve the desired properties. Finally, we will develop methods for patterning and shaping these**materials on the macroscale.**The results of this work will lead to new commercial products for our partner.

应用量子材料公司——该项目的工业合作伙伴——最近开发了一种新的合成方法来设计具有独特光学特性的纳米颗粒。这些纳米颗粒具有多种潜在的商业应用，但是潜在客户要求将颗粒固定在聚合物基质中以形成块状光学材料。**这项工作的目的是开发一种将这些材料嵌入聚合物基质的方法。实现良好的混合并保持纳米材料的光学特性可能具有挑战性。实现纳米材料的良好分散，并确保混合条件不会导致纳米颗粒的降解是非常重要的。在这项工作中，我们将开发一种基于熔融混合的工艺，并**比较在这种条件下形成的复合材料的性能。我们将表征所得复合材料的光学、热学和机械性能，并确定实现所需性能所需的纳米颗粒的最小浓度。最后，我们将开发在宏观尺度上对这些材料进行图案和塑造的方法。这项工作的结果将为我们的合作伙伴带来新的商业产品。
