This study presents a detailed synthesis, characterization, and analysis of bioplasticizers derived from Thespesia populnea leaf powder (TPLP) towards developing sustainable biomaterials. Comprehensive characterization of TPLP across various analytical techniques reveals its diverse properties and potential applications. Fourier-transform infrared (FTIR) spectroscopy indicates the cellulose, hemicellulose, pectin, lipids, lignin, and aromatic compounds. UV-visible absorption spectra suggest reduced transparency attributed particle interactions and crystalline structure. XRD analysis of TPLP shows the crystallinity value of 50.69% with crystalline size around 20.49 nm, indicative of its plasticizing effect. Particle size distribution analysis indicates an average size of 12.459 μm, while differential scanning calorimetry (DSC) analysis reveals multiple thermal transitions indicative of crystallization, melting, and decomposition. These findings collectively underscore TPLP’s versatility and potential across a range of applications, including use as a plasticizer in polymer films for packaging, drug delivery systems, composite materials, high-temperature applications such as phase change material formulations. This research highlights the promising future of TPLP as a sustainable bioplasticizer in various industrial applications.
