Our previous EPSRC-funded 12 month project established the feasibility of using an electrode modified with deposited clay platelets containing grafted temperature-responsive polymer chains to capture dispersed colloid particles using temperature as the trigger. This continuation proposal aims to maximise temperature-triggered particle capture and release through improvements in our understanding of the underlying principles and to use this new technology to construct Janus particles. Janus particles are advanced colloid particles that have a diblock structure with each of the blocks having different surface energies. They are the best known stabilisers for emulsions and will also enable construction of nanoscale, functional devices. This project presents, for the first time, a method to produce Janus particles that has potential to be used on an industrial scale.

我们之前由 EPSRC 资助的为期 12 个月的项目确立了使用电极的可行性，该电极用含有接枝温度响应聚合物链的沉积粘土片进行修饰，以温度为触发条件来捕获分散的胶体颗粒。该延续提案旨在通过提高我们对基本原理的理解来最大限度地提高温度触发粒子的捕获和释放，并使用这项新技术来构建 Janus 粒子。 Janus 颗粒是先进的胶体颗粒，具有二嵌段结构，每个嵌段具有不同的表面能。它们是最著名的乳液稳定剂，也可用于构建纳米级功能器件。该项目首次提出了一种生产 Janus 颗粒的方法，该方法有可能在工业规模上使用。
