Starch-based films plasticized by glycerol reinforced with cellulose were prepared. Microcrystalline cellulose (MCC) from corn husk was extracted by pretreatment process, including delignification, bleaching and acid hydrolysis using sulfuric acid. The MCC was mixed by varying weight ratio of MCC from 0 to 60 wt%. The effects of MCC content on morphological, thermal and mechanical properties were characterized. Microcrystalline cellulose from corn husk show fibrous morphology with diameter of 10-2- ?m and average length of >10,000 ?m. The biocomposite films containing MCC were less transparent than the films without MCC. The haze of biocomposite films readily increased with the increasing amount of MCC. The incorporation of MCC improved the thermal stability, tensile strength and Young’s modulus of plasticized starch. Presence of 20 wt% of MCC in biocomposite film resulted in maximum tensile strength and Young’s modulus. The maximum tensile strength and young’s modulus of starch-based film reinforced with 20 wt% MCC were as high as 3.48 MPa and 16.91 MPa, respectively.
