Description

technical field [0001] The invention belongs to the field of intelligent materials and relates to electroactive ion polymer materials, in particular to a method for preparing an ion electroactive driver based on carboxylated bacterial cellulose Background technique [0002] Electroactive polymers are a new type of intelligent polymer materials, which can change the internal structure under the action of an external electric field, and produce various forms of mechanical responses such as stretching, bending, tightening or expansion, and have extremely strong electrical and mechanical properties. Simultaneously realize multiple functions such as driving and sensing. According to the different actuation mechanism, it can be divided into electronic type and ionic type. Among them, ionic polymer metal composites (IPMC), a typical material in ionic electroactive polymers, are widely used. [0003] IPMC is generally a composite material obtained by depositing platinum, gold and ...
