Abstract
The invention relates to a nano-crystalline cellulose reinforced graphene oxide/ polydopamine laminated bionic material and a preparation method thereof, and belongs to the technical field of laminated bionic composite materials. In order to solve the problems of poor tensile strength and toughness of a traditional bionic material, the invention provides a preparation method for the nano-crystalline cellulose reinforced graphene oxide/ polydopamine laminated bionic material. Graphene oxide and nano-crystalline cellulose are respectively dissolved in deionized water to be mixed, then, the pH (Potential of Hydrogen) value of the solution is regulated to 8.5, dopamine is added to be stirred evenly, vacuum suction filtration is carried out to form a film, and the film is dried to obtain the nano-crystalline cellulose reinforced graphene oxide/ polydopamine laminated bionic material. According to the nano-crystalline cellulose reinforced graphene oxide/ polydopamine laminated bionic material, the nano-crystalline cellulose is taken as a reinforcement phase to improve the tensile strength, the elasticity modulus and the toughness of the laminated bionic material; through HI (Hydroiodic Acid) solution reduction and CuCl2 solution processing, the laminated bionic material has better electric conduction performance, and therefore, the laminated bionic material can be applied to fields,including aerospace, flexible anodes, artificial muscles, tissue engineering and the like.
