项目摘要

There are unmet needs to develop effective materials to absorb infra-red (IR) light, e.g., for IR signature management. With unique optoelectronic properties, nanoparticles especially in non-spherical shape have demonstrated to be spectral selective absorbers, where the electromagnetic absorption bands strongly depend on nanoparticles' geometries. However, it is challenging to synthesise such nanoparticles with desired geometries and properties in a controllable and reproducible format, and formulate them into stable materials for large-scale production. This project aims to develop nanocomposite coatings (paints) incorporating silver nanorods (AgNRs) to selectively absorb IR electromagnetic bands. Chemistries will first be optimised for nanoparticle formation with controllable geometries. Encapsulation of the AgNRs to form stable nanoparticles with functional groups for suitable inclusion into polymers will then be established. Together with a parallel going PhD project, the formation of nanocomposite coatings in large-scale using continuous flow reactors will be developed and evaluated as IR blockers. This project will be conducted jointly by Engineering and Chemistry through an interdisciplinary approach drawing on diverse expertise and unique infrastructure available across disciplines.Candidate Requirements: Students with at least an upper second (2:1) class degree in a relevant discipline (e.g., Chemistry, Materials Science, Chemical Engineering) are invited to apply. Research experience or a Master's degree in a related area would be highly beneficial. UK/EU nationals only (due to funding restrictions).

开发吸收红外线(IR)光的有效材料的需求尚未得到满足，例如，用于IR签名管理。纳米粒子具有独特的光电性质，特别是非球形的纳米粒子是一种光谱选择性吸收材料，其电磁吸收带强烈依赖于纳米粒子的几何形状。然而，以可控和可重现的形式合成具有所需几何形状和性质的纳米粒子，并将其配制成稳定的材料用于大规模生产是具有挑战性的。该项目旨在开发含有银纳米棒(AgNRs)的纳米复合涂层(涂料)，以选择性地吸收红外电磁波段。首先将优化化学成分，以形成几何形状可控的纳米颗粒。然后，将AgNRs包裹起来，形成具有适当包结到聚合物中的官能团的稳定纳米颗粒。与一个平行进行的PHD项目一起，将开发使用连续流动反应器大规模形成纳米复合涂层，并将其作为IR阻断剂进行评估。这个项目将由工程学和化学通过跨学科的方法联合进行，利用不同学科的不同专业知识和独特的基础设施。条件要求：邀请具有相关学科(例如化学、材料科学、化学工程)第二级以上(2：1)学位的学生申请。有相关领域的研究经验或硕士学位者优先。仅限英国/欧盟国民(由于资金限制)。
