چکیده انگلیسی
Various contents of lignin-coated cellulose nanocrystals (L-CNC) were incorporated into methacrylate (MA) resin and their mixture was used to prepare nanocomposites via 3D stereolithography (3D-SL) printing. Gaps were found between the L-CNC and MA matrix in 3D-SL printed nanocomposites before postcure. However, gaps decreased after postcure due to interactions between the L-CNC and MA molecules. Mechanical properties increased with the addition of 0.1% and 0.5% L-CNC after postcure, and the thermal stability was improved at 0.5% L-CNC. Dynamic mechanical analysis demonstrated that incorporation of L-CNC increased the storage modulus in the rubbery plateau. The loss factor had two transition regions, which gradually changed by merging together with increasing L-CNC content, and a broadening of the transition region was observed after postcure. In particular, the mechanical and thermal properties of 3D-SL printed nanocomposites, after postcure, exhibited higher improvement than those before postcure.
