제목 High-molecular-weighted polyvinyl chloride (PVC) gel-based varifocal microlens
초록 In fourth industrial revolution, the demand for optical modules is increasing because they need to acquire information around place and things. Recently, the introduction of focus-tunable adaptive lenses in the optical modules have attracted. Although emerging liquid-based or solid-based, variable-focus micro-lenses have been widely investigated, they rely on the movement of fluid, which can be subject to external disturbances and fluidic leakages during the operations as well as still should utilize complicated mechanical parts to realize tunable focal lengths. In this study, unlike the liquid- or solid-based lenses, we developed an electroresponsive, transparent, and non-ionic polyvinyl chloride (PVC) gel as a smart material to open up new perspectives on practical tunable optics. We investigated the molecular weight effect of PVC polymer on the optical, electrical, dielectric, and mechanical performance of the plasticized PVC gels, which enables higher physical crosslinking density.
