Green Synthesis of Lignin and Lignin-Based Nanoparticles from Rice Husk for several Applications

This research aims to develop and evaluate eco-friendly lignin-based nanoparticles derived from rice husk for dual applications in biodegradable films and sunscreen formulations. The project focuses on synthesizing spherical lignin nanoparticles (sLNPs) and hybrid lignin nanoparticle composites through green, sustainable methods. These nanomaterials will be thoroughly characterized using SEM, TEM, DLS, FTIR, UV-Vis, and TGA to determine their structural, functional, and thermal properties. Their incorporation into sunscreen emulsions will be assessed by measuring SPF performance, antioxidant activity, formulation stability, and UV-resistance, while similar evaluations in biodegradable films will investigate reinforcement and barrier enhancements. Overall, the study compares the functional advantages of lignin and hybrid nanoparticle systems to identify the most effective materials for sustainable packaging and cosmetic applications.
