Abstract

We present the creation of an alignment layer for liquid crystal molecules based on DNA from fish waste and a selected cationic surfactant. The implemented biodegradable DNA-based surface offers excellent optical and physical properties, cost-effectiveness, and environmental benefits compared to conventional polymers. Our findings demonstrate that the biopolymer DNA-DODA effectively induces homeotropic alignment of nematic liquid crystals, which was confirmed by topography visualization using atomic force microscopy, macroscopy, and polarizing optical microscopy observations. Anchoring energy and response time studies in the well-known electro-optical effect show that DNA-DODA exhibits molecular interaction strengths comparable to those of commercial polyimide. The successful implementation of DNA-DODA as an alignment layer highlights its promise for next-generation technologies, including flexible, sustainable, and biocompatible optical devices.

摘要

我们展示了基于鱼废料中的DNA和一种选定的阳离子表面活性剂创建用于液晶分子的取向层。与传统聚合物相比，所实现的基于可生物降解DNA的表面具有出色的光学和物理性能、成本效益以及环境效益。我们的研究结果表明，生物聚合物DNA-DODA能有效诱导向列相液晶的垂直取向，这通过原子力显微镜的形貌可视化、宏观观察和偏振光学显微镜观察得到了证实。在著名的电光效应中对锚固能和响应时间的研究表明，DNA-DODA表现出与商业聚酰亚胺相当的分子相互作用强度。DNA-DODA作为取向层的成功应用突出了其在包括柔性、可持续和生物相容性光学器件在内的下一代技术中的前景。
