Recent advances in stimuli-responsive coatings enable their integration as functional elements in nanotechnologies such as microfluidics, Micro Electro-Mechanical Systems (MEMS) where interfacial forces strongly influence the device performance because of the large surface-to-volume ratio. However, responsive coatings are suffering from major shortcomings: (i) lack of responsiveness rapidity, selectivity and reversibility, (ii) poor environmental stability, (iii) limited understanding of the structure–function relationship, which are all critical to design reliable rules for building multifunctional surfaces. Using approaches from surface chemistry, polymer sciences and self-assembly, the proposed program aims to overcome these limitations by developing and investigating a new generation of responsive hierarchical micro/nano-structured coatings whose physical properties (structure and mechanical properties) and surface chemistry can be tuned independently and reversibly using different external stimuli (light, temperature, pH, ionic strength).

刺激响应涂层的最新进展使其能够作为功能元件集成在纳米技术中，如微流体、微电子机械系统(MEMS)，在这些技术中，由于大的比表面积比，界面力强烈地影响着器件的性能。然而，响应性涂层的主要缺点是：(I)缺乏响应性、快速性、选择性和可逆性，(Ii)环境稳定性差，(Iii)对结构-功能关系的了解有限，这些都是设计可靠的多功能表面规则的关键。该计划利用表面化学、聚合物科学和自组装的方法，旨在通过开发和研究新一代响应性层次化微/纳米结构涂层来克服这些限制，这种涂层的物理性能(结构和机械性能)和表面化学可以根据不同的外部刺激(光、温度、pH、离子强度)进行独立和可逆的调整。
