光制造的表面褶皱的混合有机-无机复合材料薄膜含有稳定的CTA（+）和PVP的TiO 2纳米粒子，允许制备可调的分层结构与环境响应性能。随着相对湿度的变化，薄膜通过吸水膨胀，并在微米尺度上平滑褶皱;这种反应是可逆的，可以进行干湿循环。
Photo-fabrication of surface-wrinkled hybrid organic-inorganic composite films containing TiO2 nanoparticles stabilized with CTA(+) and PVP allows the preparation of tunable hierarchical structures with environmentally responsive properties. With changes in relative humidity, the film swells by absorbing water and smooths out the wrinkles at the micrometer scale; this response is reversible and wet-dry cycles can be run.
