Abstract:In this study, carboxyethyl microfibrillated cellulose/graphene composite film, carboxyethyl microfibrillated cellulose/polyaniline composite film, and carboxyethyl microfibrillated cellulose/graphene/polyaniline composite film were prepared respectively by physical mixing method, chemical in-situ adsorption polymerization method, and the combination of physical blending and chemical in-situ adsorption polymerization method using coating forming method with carboxyethyl microfibrillated cellulose as matrix. The micro morphology, chemical structure, hydrophobicity, thermal stability, mechanical and electrochemical properties of the film were characterized. The results showed that carboxyethyl microfibrillated cellulose had good film-forming property and could act as carrier and dispersant. After compounding graphene or polyaniline, the mechanical and electrochemical properties of the composite film increased significantly, among which, graphene could improve the thermal stability of the film, while polyaniline could increase the hydrophobicity of the film. In addition, when 10% graphene and 30% polyaniline were compounded, it showed a synergistic effect on the electrochemical properties of the carboxyethyl microfibrillated cellulose/graphene/polyaniline composite film. |
