Abstract

We have developed a photo-mobile polymer film, that combines organic and inorganic materials, to allow for controlled motion that can be triggered by light or heat. Our film is made using recycled quartz and consists of two layers: a multi-acrylate polymer layer and a layer containing oxidized 4-amino-phenol and N-Vinyl-1-Pyrrolidinone. The use of quartz in our film also gives it a high temperature resistance of at least 350 °C. When exposed to heat, the film moves in a direction that is independent of the heat source, due to its asymmetrical design. Once the heat source is removed, the film returns to its original position. ATR-FTIR measurements confirm this asymmetrical configuration. This technology may have potential applications in energy harvesting, due to the piezoelectric properties of quartz.

摘要

我们开发了一种结合有机和无机材料的光控移动聚合物薄膜，以实现可由光或热触发的可控运动。我们的薄膜采用回收石英制成，由两层组成：一层是多丙烯酸酯聚合物层，另一层是含有氧化4-氨基苯酚和N-乙烯基-1-吡咯烷酮的层。我们薄膜中石英的使用还使其具有至少350°C的耐高温性。当暴露于热时，由于其不对称设计该薄膜会朝着与热源无关的方向移动。一旦移除热源，薄膜就会回到其原始位置。衰减全反射傅里叶变换红外光谱（ATR-FTIR）测量证实了这种不对称结构。由于石英的压电特性，这项技术可能在能量收集方面有潜在应用。
