NOVELTY - Preparing ionic electroactive driver comprises adding an appropriate amount of deionized water to the bacterial cellulose dispersion to dilute under stirring to prepare a uniform bacterial cellulose dispersion, utilizing (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) oxidation method to oxidize bacterial cellulose, and then centrifuging to obtain flocculent carboxylated bacterial cellulose. A certain amount of carboxylated bacterial cellulose is added to polyvinyl alcohol, 1-ethyl-3-Methylimidazolium tetrafluoroborate (EMIM BF4) ionic liquid, graphene and an appropriate amount of deionized water in sequence to obtain uniform carboxylated bacterial cellulose after stirring and ultrasonic vibration at room temperature to obtain polyvinyl alcohol-ionic liquid-graphene dispersion. The air bubbles in the carboxylated bacterial cellulose-polyvinyl alcohol-ionic liquid-graphene dispersion are pumped out in a vacuum state. USE - Method for preparing ionic electroactive driver based on carboxylated bacterial cellulose. ADVANTAGE - The method provides a low cost, green and environment-friendly, simple and reliable preparation method of ionic electroactive driver based on carboxylation bacterial cellulose and graphene. DETAILED DESCRIPTION - Preparing ionic electroactive driver comprises adding an appropriate amount of deionized water to the bacterial cellulose dispersion to dilute under stirring to prepare a uniform bacterial cellulose dispersion, utilizing (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) oxidation method to oxidize bacterial cellulose, and then centrifuging to obtain flocculent carboxylated bacterial cellulose. A certain amount of carboxylated bacterial cellulose is added to polyvinyl alcohol, 1-ethyl-3-Methylimidazolium tetrafluoroborate (EMIM BF4) ionic liquid, graphene and an appropriate amount of deionized water in sequence to obtain uniform carboxylated bacterial cellulose after stirring and ultrasonic vibration at room temperature to obtain polyvinyl alcohol-ionic liquid-graphene dispersion. The air bubbles in the carboxylated bacterial cellulose-polyvinyl alcohol-ionic liquid-graphene dispersion are pumped out in a vacuum state. The dispersion liquid is poured into a mold, and left in a drying oven to obtain carboxylated bacterial cellulose-polyvinyl alcohol-ionic liquid-graphene polymer film. The prepared carboxylated bacterial cellulose-polyvinyl alcohol-ionic liquid-graphene polymer film is immersed in the PEDOT:PSS electrode solution by dip-dyeing method, and then taken out and dried to obtain carboxylated bacterial cellulose-polyvinyl alcohol-ionic liquid-graphene ionic electroactive actuator.
