Photodegradable polymers constitute an emerging class of materials that are expected to possess advances in the areas of micro/nano- and biotechnology. Herein, we report a green and effective strategy to fabricate light-responsive surface micropatterns by taking advantage of photodegradation chemistry. Thanks to the molecular chain breakage during the photolysis process, the stress field of photodegradable polymer-based wrinkling systems undergoes continuous disturbance, leading to the release/reorganization of the internal stress. Revealed by systematic experiments, the light-induced stress release mechanism enables the dynamic adaption of not only thermal-induced labyrinth wrinkles, but uniaxially oriented wrinkle microstructures induced by mechanical straining. This method paves the way for their diverse applications, for example, in optical information display and storage, and the smart fabrication of multifunctional surfaces as demonstrated here.

可光降解聚合物薄膜上具有多功能表面特性的光调制表面微图案

可光降解的聚合物构成了一类新兴的材料，有望在微/纳米和生物技术领域取得进展。在本文中，我们报告了一种利用光降解化学技术制造光响应性表面微图案的绿色有效策略。由于在光解过程中分子链断裂，基于光降解聚合物的起皱系统的应力场受到连续干扰，从而导致内部应力的释放/重组。通过系统性实验揭示，光诱导的应力释放机制不仅能够动态适应热诱导的迷宫式皱纹，而且还能够动态适应由机械应变诱导的单轴取向的皱纹微结构。这种方法为他们的多样化应用铺平了道路，例如，
