Abstract

In this study, we synthesized environmentally friendly cyclohexanedicarboxylate (CHDC) plasticizers and developed a novel polyvinyl chloride (PVC) gel using a CHDC plasticizer for focus-tunable microlens. The fabricated PVC/CHDC gel exhibited excellent optical transparency (92.6 % at 550 nm), a high dielectric constant (2485 at 1 Hz), and ultra-soft elasticity (Young’s modulus of 0.90 × 10^-4 MPa). The focus-tunable microlens based on the PVC/CHDC gel achieved a wide focal length range from 5.3 mm to 29.7 mm under applied voltages of 50–350 V. Notably, the PVC/CHDC gel-based microlens demonstrated superior performance, with faster response time (0.4 s) and lower leakage current (<2 μA) compared to conventional PVC/DBA gel-based microlens. Biocompatibility and minimal plasticizer migration (>97.5 % retention) suggest that PVC/CHDC gel holds promise as a candidate for various electronic and optical devices intended for use within the human body.

环保电活性聚氯乙烯凝胶型可调焦微透镜

在这项研究中，我们合成了环境友好型环己烷二甲酸酯（CHDC）增塑剂，并利用 CHDC 增塑剂开发了一种新型聚氯乙烯（PVC）凝胶，用于聚焦可调微透镜。制备的聚氯乙烯/CHDC 凝胶具有出色的光学透明度（550 纳米波长下为 92.6%）、高介电常数（1 Hz 时为 2485）和超软弹性（杨氏模量为 0.90 × 10-4 兆帕）。与传统的 PVC/DBA 凝胶微透镜相比，基于 PVC/CHDC 凝胶的可调焦微透镜具有更优越的性能，响应时间更快（0.4 秒），漏电流更低（2 μA）。PVC/CHDC凝胶的生物相容性和极低的增塑剂迁移率（97.5%的保留率）表明，PVC/CHDC凝胶有望成为在人体内使用的各种电子和光学设备的候选材料。

期刊介绍： Journal of Industrial and Engineering Chemistry is published monthly in English by the Korean Society of Industrial and Engineering Chemistry. JIEC brings together multidisciplinary interests in one journal and is to disseminate information on all aspects of research and development in industrial and engineering chemistry. Contributions in the form of research articles, short communications, notes and reviews are considered for publication. The editors welcome original contributions that have not been and are not to be published elsewhere. Instruction to authors and a manuscript submissions form are printed at the end of each issue. Bulk reprints of individual articles can be ordered. This publication is partially supported by Korea Research Foundation and the Korean Federation of Science and Technology Societies.
