Abstract

Developing materials that combine superhydrophobic properties with high optical transmittance poses a significant challenge. In this study, hydroxyl-terminated polydimethylsiloxane (HT-PDMS) and isosorbide (ISB) were polymerized in a single step to create a covalently bonded optical polycarbonate material. By inducing the formation of micro-papillary and lotus-shaped nanoscale structures via a solvent-triggered process, we significantly enhanced the “air cushion” effect, achieving a structure scale of approximately 5–7 μm. This resulted in a water contact angle of 157° while maintaining over 90 % optical transmittance. The structures were uniformly distributed throughout the polymer matrix, leading to a 500 % increase in tensile strength at break compared to pure isosorbide polycarbonate, with a maximum strength exceeding 50 MPa. These multifunctional materials show great promise for applications in smart windows, solar panels, camera lenses, and other optoelectronic devices.

轻松制备具有超疏水和高透光率的半结晶生物基聚碳酸酯

开发兼具超疏水特性和高透光率的材料是一项重大挑战。在这项研究中，羟基封端聚二甲基硅氧烷（HT-PDMS）和异山梨醇（ISB）通过一步聚合生成了共价键合的光学聚碳酸酯材料。通过溶剂触发工艺诱导形成微毛细管和莲花状纳米结构，我们显著增强了 "气垫 "效应，实现了约 5-7 μm 的结构尺度。这使得水接触角达到 157°，同时保持了 90% 以上的透光率。这些结构均匀地分布在整个聚合物基体中，与纯异山梨醇聚碳酸酯相比，断裂拉伸强度提高了 500%，最大强度超过 50 兆帕。这些多功能材料在智能窗户、太阳能电池板、相机镜头和其他光电设备中的应用前景广阔。
