There are unmet needs to develop effective coatings to absorb infra-red (IR) radiation, 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 depends on nanoparticles' geometries. However, it is challenging to synthesise such nanoparticles with desired geometries and properties in a controllable and reproducible format, and with large-scale production. This project aims to develop nanocomposite coatings incorporating silver nanorods (AgNRs) to selectively absorb IR electromagnetic bands. Chemistries will first be optimised for nanoparticle formation with controllable geometries. Design and construction of continuous-flow reactors will be carried out for large-scale production of AgNRs. AgNRs-embedded nanocomposite coatings will then be formulated 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.

对于开发有效的涂层以吸收红外（IR）辐射，例如，用于IR签名管理。非球形纳米粒子具有独特的光电性能，是一种光谱选择性吸收体，其电磁吸收带与纳米粒子的几何形状密切相关。然而，以可控和可再现的形式合成具有所需几何形状和性质的此类纳米颗粒并进行大规模生产是具有挑战性的。本计画的目的是开发含有银奈米棒（AgNR）的奈米复合涂层，以选择性地吸收红外线电磁波带。化学将首先被优化用于具有可控几何形状的纳米颗粒形成。为大规模生产AgNR，将设计和建造连续流反应器。然后将AgNR嵌入的纳米复合材料涂层配制并作为IR阻断剂进行评价。该项目将由工程和化学通过跨学科的方法联合进行，利用跨学科的各种专业知识和独特的基础设施。
