Construction method for natural bipolar biomass gel artificial muscle device

Abstract

The invention provides a construction method for a natural bipolar biomass gel artificial muscle device. Theconstruction method is characterized by comprising the following three steps of: firstly, carrying out biological crosslinking reaction on natural a high-molecular polymer sodium alginate and carboxylated chitosan to obtain a biomass gel electricactive film with excellent biocompatibility and bipolar electric actuation behavior; secondly, by utilizing a hydrogen bond synergistic effect between sodium alginate and MXene surface functional groups, preparing a non-metal electrode membrane solution through direct water-bath blending, wherein the non-metal electrode membrane solution is high in conductivity, resistant to bending, safe and non-toxic after being formed into a membrane; and finally, sequentially and alternately laminating and constructing the electricactive film and the electrode film solution to form an artificial muscle device with a multi-layer hamburger-like structure, wherein an internal interface synthesis layer of the artificial muscle device is good in adhesion; the response deformation degree, the reversible actuation property and the movement range are increased; and very excellent electric-chemical-mechanical properties are shown. The construction method has the advantages of being scientific, reasonable, easy and convenient to operate, environmentally friendly, high in applicability and good in effect.

Description

technical field [0001] The invention relates to a construction process method of an artificial muscle device, in particular to a construction method of a natural amphoteric biomass gel artificial muscle device. Background technique [0002] Traditional power systems, such as internal combustion engines, have been widely used in various devices; however, there are still many limitations in making them reproduce the motion of living organisms, such as difficulty in miniaturization and forced continuous operation. Then, artificial muscle came into being, which refers to a device that can reversibly shrink and expand in response to specific stimuli to replicate the movement behavior of living organisms, which is similar to the phenomenon of biological muscles responding to nerve signals. At present, there are many kinds of materials used in the research and development of artificial muscle devices, such as polymer fibers, elastomers and shape memory alloys; based on different co...
