A rise in demand for disposable consumer electronics such as smart packaging, wearable electronics, and single-use point-of-source sensors requires the development of eco-friendly compostable electronic materials. Chitosan is derived from crustacean waste offers high dielectric constant values without requiring rigorous purification, making it sustainable large-scale device manufacturing. When processed acidic media, protonated backbone chitosan pairs with counterions acid dissociation to form thin films electrical double layers (EDLs) tunable capacitive properties. We report importance choice when processing by surveying a series halogenated biosourced acids varying pKa solutions different pH values. Oxalic outperforms other acids, maximum areal capacitance 161 nF·mm–2. Tartaric citric acid, despite lower values, showed promising results stable EDL reproducibility, them optimal large-area The incorporation sorbitol plasticizer boosts formation onset all chitosan–acid combinations 1 × 103–105 Hz improves reproducibility. High-performing single-walled carbon nanotube film transistors were made using chitosan-based dielectrics treated sorbitol, leading transconductance ≈5.2 μS Ion/Ioff 105. capacitors remain functional after one year storage ambient conditions. Overall, this study demonstrates durable high-performance based on stresses use plasticizing additives, sorbitol.
