Abstract:In this study， bleached bagasse pulp was used as raw material to prepare cellulose nanofibril （CNF） by mechanical grinding method. CNF was prepared into nano paper-based films （CNP） by flow-casting， and the undried CNP was mercerized to obtain mercerized CNP （Me-CNP）. Two kinds of nano paper-based films were prepared by coating acrylic ABPE-10 on the surface of CNP and Me-CNP to prepare CNP-Co and Me-CNP-Co， respectively. After the Pickering emulsion was prepared by stabilizing ABPE-10 with CNF， CNP-P was prepared by the flow-casting method and Pickering emulsion method. By comparing the optical properties， thermal stability and water barrier properties of nano paper-based films prepared by different methods， it was found that the mechanical toughness of CNP could be improved by mercerization treatment. The transparency of both nano paper-based films prepared by surface coating and Pickering emulsion method was more than 85%， the thermal decomposition temperature was more than 345 ℃， and the water contact angle was greater than 90°. Additionally， all the nano paper-based films exhibited good mechanical flexibility.
