Lignin, biodegradable and second abundant material after cellulose in plants, has transitioned from a by-product to a valuable material that enhance properties and functionalities through the use of lignin nanoparticle(LNP) in polymer nanocomposites(PNCs). In this study, we have analyzed the microstructure of PNCs incorporating LNPs. Specifically, we examined the role of LNPs by analyzing the dynamics and rheological properties of PNC system. These systems are based on polyvinyl alcohol(PVA) and fabricated by solution casting. We examined microstructure across various molecular weights with LNP contents. Small-Angle X-ray Scattering (SAXS) and rheometer are employed to reveal the dispersion state of LNPs within the polymer matrix. These structural differences in solution state affect the crystallinity and thermal properties after drying process. Through these findings, we aim to understand the role of LNPs and elucidate the mechanisms behind the enhancement of polymer properties at the microstructural level.
