The major challenges for directly converting lignocellulosic biomass into available materials in place of synthetic polymer materials are the complex chemical鈥損hysical structure and the narrow processing windows of the resources. In the present study, homogeneous chemical modification of sugarcane bagasse with phthalic anhydride was taken to be an improved strategy to meet the challenges. FT-IR and liquid-state NMR spectra confirmed the chemical structure of the sugarcane bagasse phthalates. Sugarcane bagasse phthalates with weight percentage gain higher than 32.9% were readily dissolved in organic solvents, and film materials were prepared by solution casting from the sugarcane bagasse phthalates. Thermogravimetric analysis and differential scanning calorimetry was applied to study the thermal behaviors of the sugarcane bagasse phthalates. Scanning electron microscope, atomic force microscopy and tensile testing were applied to study the morphologies and mechanical properties of the films. The results indicated that sugarcane bagasse was plasticized by homogeneous chemical modification with phthalic anhydride.
