THz Spectroscopy Analysis of Crystallinity Optimization for Enhanced Piezoelectricity in Biodegradable Poly-L-Lactide Acid

Abstract

Our research delves into both the fabrication and analysis of biodegradable Poly-L-Lactic Acid (PLLA) films. Specifically, we investigate how stretching impacts the piezoelectric properties of PLLA films. By employing advanced techniques such as Terahertz Time-Domain Spectroscopy (THz-TDS), we aim to unveil previously undiscovered aspects of PLLA's behavior under strain. This includes quantifying changes in crystallinity and observing alterations in piezoelectric responses and absorption spectra. Our study not only emphasizes the fabrication of PLLA as a biodegradable material but also explores its piezoelectric performance, involving methods such as inducing strain and measuring the piezoelectric output. Through this multifaceted approach, we strive to contribute to the progression of sustainable biomaterials and the design of innovative biomedical devices.
