Bio‐Based Piezoelectrets from Polylactic Acid and Natural Waxes: A Sustainable Approach for Energy Harvesting

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A novel polylactic acid/wax electret composite is developed, combining biodegradability with long‐term charge stability. The study investigates charge storage behavior, structural morphology, and thermal performance. Results reveal a notable charge retention recovery after thermal stress and exhibit stable surface potential over 2 kV. This eco‐friendly
