Research on Parylene-C application to wearable organic electronics: in the respect of substrate type

Poly(para-xylylene) polymers, also known as parylene and its derivatives, have attracted attention as functional materials in organic electronics. Among the various parylene derivatives, Parylene-C is a unique material that has gained attention in various industries, including wearable electronic devices. Parylene-C is particularly suitable for coating and protecting electronic components because of its high dielectric strength, biocompatibility, and chemical resistance. Herein, we compare three different substrates for application in wearable organic electronics with Parylene-C with respect to the deposition process. We identified the morphology and electrical properties of Parylene-C with a pristine layer and practical electronic devices (capacitors and transistors). Based on this analysis, we applied integrated logic devices with optimized organic transistors on a Parylene-C substrate. Therefore, we expect that this study will aid in the selection and use of versatile substrate types for the fabrication of organic electronics with Parylene-C materials.
