Shellac as Dielectric Materials in Organic Field-Effect Transistors: From Silicon to Paper Substrates

Abstract Recent advances in the design and preparation of electroactive materials, particularly semiconducting conductive polymers, have resulted creation novel organic electronics with advanced functionality performance competitive that devices made silicon. With an increasing number printed being engineered produced at a larger scale, environmental cost final electronic (life cycle, impact, etc) needs to be considered. While e-waste is already growing global problem, improving sustainability emerging through careful materials selection highly desirable. In this work, we explore use shellac as sustainable greener dielectric material field-effect transistors. A examination combination diketopyrrolopyrrole-based polymers was performed on rigid substrates atomic force microscopy (AFM) fabrication thin film All from green showed good device characteristics. Building investigation, further integrated paper fabricate paper-based Thin samples based both silicon wafer were characterized by AFM investigate solid-state morphology selected materials. Through optimization architecture processing time, characteristics performances (average charge mobilities on/off current ratios) comparable those prepared wafers, confirming shellac, can advantageous used for renewable feedstocks components.
