The central aim is to explore how the processing of chitosan, particularly hydration, influences its piezoelectric-like properties.
Systematic investigation of processing conditions affecting chitosan films.
Focus on hydration levels and their impact on piezoelectric responses.
Achieved d33 values of 11.3 pC N−1, revealing strong piezoelectric-like effects.
Hydration significantly governs the piezoelectric-like responses in chitosan.
Abstract
We systematically reveal for the first time how processing, specifically hydration, governs piezoelectric-like responses in chitosan, achieving d 33 values of 11.3 pC N −1 .
