英文摘要: A lignin-based industrial waste was converted to a value-added reinforcing agent for epoxy matrix composites. Thus, a facile three-step strategy including methylolation, epoxidation and carbonation (i.e., CO2 fixation) was conducted to prepare the reactive filler as a cyclocarbonated lignosufonate (CLS). Then, CLS (10, 20, and 30 wt%) was blended with DGEBA epoxy resin followed by amine-curing to produce the biocomposites. Spectral, thermal, thermomechanical, mechanical and morphological properties of the CLS-epoxy composites were studied by FTIR, DSC/TGA, DMTA, tensile/flexural testing and SEM, respectively. In comparison with the neat DGEBA network, by increasing the CLS% in the biocomposite, tensile strength decreased, flexural modulus was well-preserved, and the Young's and storage modulus were greatly improved. It was attributed to stiffening effect of the modified lignin particles as well as the formation of urethane bonds and intermolecular interactions such as hydrogen bonding. The glass transition temperature for the biocomposites with 10 and 20 wt% of CLS showed negligible change. The incorporation of the carbonated lignin into epoxy resin could provide an eco-effective approach toward inexpensive high performance biocomposites. © 2017 Elsevier Ltd Citation statistics:
