Embodiment Construction

[0037] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0038] combine figure 1 and figure 2 , it can be seen that a variety of stimuli-responsive actuators with a core-shell structure based on carbon nanocomposite fibers are characterized in that the various stimuli-responsive actuators are carbon nanotube composite yarns with a conductive helical structure, and the helical The preparation method of the carbon nanotube composite yarn of the structure is as follows: the high-strength organic fiber (such as polyimide, nylon 6,6, etc.) is twisted to form an organic yarn 2 with a certain twist, and the organic yarn 2 As a core, through a concentric mandrel cladding device (such as figure 1 ) winding a carbon nanotube film 4 with a certain twist angle, and infiltrating silicon rubber at the carbon nanotube film 4 as an outer shell to obtain a carbon nanotube composite fiber with a core-shell structure; the above-mentioned...

Abstract

The invention relates to the technical field of software drivers, in particular to a carbon nanocomposite fiber based multi-stimulus response driver of a core-shell structure. Organic fibers with highstrength are adopted, the organic fibers are twisted and prepared into a yarn with a certain twist, the organic yarn is used as a core, a carbon nano film with a certain twist angle is wound througha concentric shaft coating device, and silicone rubber is infiltrated at the film to serve as an outer shell. The carbon nanocomposite fiber of the core-shell structure is twisted to form the yarn ofa spiral structure, the carbon nanotube composite yarn of the spiral structure is used as an electrically conductive fiber material, mechanical vibration output with high deformation and high frequency can be continuously generated after a certain amount of current passes through the fiber material, and the mechanical vibration output can be used as an efficient driver. In addition, being capableof responding quickly and efficiently to external electrothermal stimuli, the multi-stimulus response driver provided by the invention can also be used for driving by solvents and thermal stimuli, canbe used in different occasions according to needs, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of soft actuators, in particular to a variety of stimulus-responsive actuators with a core-shell structure based on carbon nanocomposite fibers. Background technique [0002] Soft actuators are a nascent field that can convert electrical, thermal, electrochemical, or chemical forms of energy into mechanical energy for deformation such as stretching, contraction, torsion, rotation, or bending. They have broad application prospects in exoskeletons, prosthetic devices, flexible manipulators, etc. Soft actuators are made of flexible materials such as electroactive polymers, silica gel, shape memory alloys, shape memory polymers, hydrogels, and carbon nanotubes that can withstand large strains. Among them, shape memory alloy fibers have been used as drivers since the 1870s. Thermally driven or electrothermally driven shape memory alloy fibers show good driving performance, and their power density reaches 930J / kg...
