ABSRACT In this study, the oil absorption capacity of maleic anhydride grafted polypropylene anchored magnetic cellulose nanocomposites (MAPP-a-MCNFs/PP) was investigated. Carboxylated cellulose nanofibrils (CCNFs) were prepared from bamboo strips. The sol-gel process using magnetite nanoparticles (Fe3O4 NP) and CCNFs were utilized to synthesize magnetic cellulose nanofibrils (MCNFs). Surface modification of MCNFs were done through hydrolysis–condensation reaction using 3-aminopropyltriethoxysilane (γ-APTES) coupling agent, followed by amidation with maleic anhydride grafted polypropylene (MAPP) to produce maleic anhydride grafted polypropylene anchored magnetic cellulose nanofibrils (MAPP-a-MCNFs). The MAPP-a-MCNFs/PP nanocomposite was characterized with FTIR, TGA and SEM. The nanocomposites absorb heavy crude oil fast and selectively on water surface, and the removal of the absorbed oils from the water surface was readily achieved under a magnetic field. This study proposes an economic and novel method for the large-scale preparation of superabsorbent nanocomposites, making them a promising candidate for the efficient and sustainable cleaning of oil spills.
