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 FTIR 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.

친수성 리그닌 표면을 polypropylene-graft-maleic anhydride(MAPP)로 개질하여 미세섬유상 셀룰로오스와 함께 폴리프로필렌 바이오 복합재의 혼합 보강재로 사용하였다. FTIR과 SEM/EDX를 이용하여 개질 전 리그닌 표면에 MAPP의 화학결합을 통한 리그닌 표면개질을 확인하였다. 리그닌 표면개질 효과를 비교하기 위하여 개질 전 리그닌을 이용한 3성분(미세섬유상 셀룰로오스/리그닌/폴리프로필렌) 바이오 복합재를 대조군으로 함께 비교하였다. 리그닌과 미세섬유상 셀룰로오스의 혼합비율에 따라 폴리프로필렌 바이오 복합재의 열적 특성과 기계적 특성이 의존하였으며, MAPP로 개질된 리그닌(MAPP-Lignin)에 의한 3성분 바이오 복합재의 인장강도와 인장탄성률은 개질전 리그닌을 사용하였을 때보다 증가하였다.
