제목 Modification of Lignin for Epoxy Composites
초록 Lignin is a second largest aromatic biomacromolecules in cellular walls of plants and synthesized from monolignol. Nowadays, Lignin is obtained in large quantities. So, it is available in applications such as economic biofuels and bioplastics, industrially available lignin has failed to deliver the desired properties of polymer composite materials primarily due to its low molecular weight and solubility. In this experimental, lignin/epoxy composite materials were fabricated by the modification of lignin. Lignin was modified by activator regenerate atom transfer polymerization of acrylic monomer (ARGET ATRP) to improve solubility for an epoxy resin. The curing process of lignin/epoxy was performed with the curing agent and accelerator in a heating oven. The physical properties of the modified lignin/epoxy composites were evaluated and enhanced compared with the unmodified lignin/epoxy composites.
