Problems solved by technology

If cellulose paper can be used to prepare flexible actuating materials, it is of great significance for the research and application expansion of flexible actuators, but there are relatively few works in this area, especially the flexible Fe 3 o 4 / PEDOT:PSS / Cellulose paper-based composite folding actuator, which has not been reported so far

Abstract

The invention relates to a method for preparing a paper-based folding actuator under stimulation of multiple physical fields. The method comprises the following steps: firstly, drawing the shape of the actuator by drawing a wax wall on cellulose paper; then, adding dropwise a conductive polymer PEDOT:PSS solution, and performing drying at room temperature with the help of an organic glass plate toprepare a PEDOT:PSS / cellulose paper-based composite; adding dropwise a Fe3O4 nanoparticle suspension onto the PEDOT:PSS / cellulose paper-based composite, performing drying at room temperature with thehelp of the organic glass plate, and taking down the paper-based composite to prepare a Fe3O4 / PEDOT: PSS / cellulose paper-based composite; cutting the Fe3O4 / PEDOT: PSS / cellulose paper-based compositealong a wax wall pattern according to design requirements of folding deformation, and pasting a transparent adhesive tape one side to prepare the flexible Fe3O4 / PEDOT:PSS / cellulose paper-based composite folding actuator. The method is relatively simple, and reversibly recoverable actuating deformation response can be produced under simulation of wet-heat-light-electricity-magnetism physical fields.

Description

technical field [0001] The invention belongs to the technical field of flexible actuators, and in particular relates to a preparation method of a paper-based folding actuator stimulated by multiple physical fields. Background technique [0002] A flexible actuator is a new type of actuator that has a large degree of freedom and can produce flexible mechanical deformations such as bending, torsion, and folding. The flexible actuator responds to deformation through different types of external stimuli, and converts electrical energy The internal energy is converted into macroscopic mechanical deformation energy, and it also has the advantages of fast response, large deformation, and low energy consumption. Therefore, flexible actuators are widely used in emerging scientific and technological fields such as artificial muscles, soft robots, and origami. [0003] Flexible actuators are mainly made of soft or elastic synthetic materials. Synthetic materials mainly include material...
