Abstract: Natural cellulose-based oil-absorption material is synthesized through radical polymerization process in 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) ionic liquid homogeneous reaction medium system,using easily-modified bagasse pretreated by 1% NaOH as raw material,N,N'-methylene-bisacrylamide (MBA) as cross-linker,ammonium persulfate (APS) as initiator and methyl methacrylate (MMA) as monomer.Influences of the dosages of monomer,initiator and cross-linker,reaction time and reaction temperature on grafting effect are investigated.The morphology,structure and crystallinity of bagasse cellulose before and after grafting are characterized by scanning electron microscope (SEM),Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD).The study confirms the grafted copolymer is successfully grafted with a rough surface and a reduced crystallinity.Under the optimum conditions,the grafting rate of the prepared material can reach 471.25%,the oil-absorption capability from surface of water can reach 22.56 g·g-1 and its water absorption ratio can reach 2.55 g·g-1.The chemical modification of bagasse has been realized by means of homogeneous copolymerization method,and the as-prepared oil-absorption material can be applied to the treatment of oil pollution in marine.
