Phthalate-based plasticizers, which are commonly used for polyvinyl chloride (PVC), exhibit toxic effects on both the environment and human health, leading to the exploration of phthalate-free alternatives. In this study, phthalate-free plasticizer-based PVC (Pf-PVC) gels were developed. The molecular interactions between the PVC chains and phthalate-free plasticizers were examined, and the transmittance, dielectric constant, and leakage current of the Pf-PVC gels were also investigated. An electrically focus-tunable microlens was fabricated using the Pf-PVC gel and its focal length was successfully controlled. Because the proposed Pf-PVC gel is free of toxic chemicals, Pf-PVC gel-based microlens holds significant promise as an actuator material in various electronic and optical devices for the human body.

用于电调焦微透镜应用的不含邻苯二甲酸盐增塑剂的聚氯乙烯凝胶


通常用于聚氯乙烯 (PVC) 的邻苯二甲酸酯类增塑剂对环境和人类健康都具有毒性作用，因此人们开始探索不含邻苯二甲酸酯的替代品。在这项研究中，开发了不含邻苯二甲酸盐增塑剂的 PVC (Pf-PVC) 凝胶。研究了 PVC 链和不含邻苯二甲酸酯增塑剂之间的分子相互作用，并研究了 Pf-PVC 凝胶的透射率、介电常数和漏电流。利用Pf-PVC凝胶制备了电调焦微透镜，并成功控制了其焦距。由于所提出的 Pf-PVC 凝胶不含有毒化学物质，因此基于 Pf-PVC 凝胶的微透镜作为人体各种电子和光学设备中的执行器材料具有重大前景。
