Abstract：In order to decrease the defects of cellulose film that is damped easily and poorly tough, the cellulose-epoxy soybean oil composite film （ESO-RC） was prepared by penetrates epoxy soybean oil into the wet cellulose membrane with its porous structure which was prepared by total cellulose extracted from gabasse. The effect of curing agent phthalic anhydrous (PA), catalyst N,N-Dimethylbenzylamine (BDMA) and solvent acetone dosage on the mechanical properties and water vapor transmission rate of the composite film was performed. And the film was characterized by fourier transform infrared spectrometer (FT-IR), X-raydiffraction (XRD), scanning electron microscope (SEM) and thermogravimetric analysis (TG). The results show that the dialysis method can produce a cellulose-epoxy soy oil composite film with uniform structure. Compared with the cellulose film, the tensile strength of the composite film was decreased, the toughness was enhanced, and the water vapor transmission rate (WVP) was reduced from 29.48 g·m-1s-1Pa-1×10-11 to a minimum of 3.08 g·m-1s-1Pa-1×10-11. And the water sensitivity was reduced, the internal structure becomes dense.
