- Abstract
- The surface modified lignin (MAPP-lignin) was prepared by using polypropylene-graft-maleic anhydride (MAPP) and used to fabricate a polypropylene bio-composite as a second reinforcing filler with microfibriled cellulose (MFC). The surface modification of the lignin was confirmed by FUR and SEM/EDX measurements. The pristine lignin was also used in the MFC/lignin/PP bio-composites as control samples. The thermal and mechanical properties of MFC/lignin/PP bio-composites depended on the mixture ratio of MFC and lignin (pristine lignin or MAPP-lignin) in the MFC/lignin/PP bio-composites. It was found that MAPP-lignin was more efficient to improve tensile strength and tensile modulus in the MFC/lignin/PP bio-composites than those of pristine lignin.
