Embodiment

[0059] 1) Configuration of PVC core printing ink:

[0060] Weigh 2g of PVC-gel powder and 22g of butylene adipate and mix them, then add 48g of THF, and stir for 2 days until the PVC powder is fully dissolved in THF, DBA and PVC are completely mixed to a colorless transparent liquid, and the solution is tested Excellent rheological properties, with shear-thinning properties, ensure that the concentration of the ink is suitable for direct writing printing.

[0061] 2) Configuration of electrode printing ink

[0062] 1) Weigh 0.35g of carbon nanotubes (type TSW3, diameter 10-20nm, length 0.5-2um), mix with 50g of isopropanol, ultrasonically disperse for 2h, then add 4.23g of PDMS-A component, and ultrasonically disperse for 2h , Magnetic stirring and heating to volatilize the isopropanol until the volatilization of isopropanol is complete, then add 0.423g of PDMS-B component, stir evenly to form a black viscous slurry.

[0063] 3) Integrated direct-write printing process

Abstract

The invention discloses a PVC-gel artificial muscle integrated printing method. The method includes the steps that polyvinyl chloride, adiponitrile poly butylene terephthalate and tetrahydrofuran areused as PVC-gel core layer materials, carbon nanotubes and silicon rubber or polyvinyl chloride and ultra-long carbon tubes and adiponitrile poly butylene terephthalate are used as electrode raw materials, and fully flexible integrated PVC-gel artificial muscles are prepared through a 3D direct writing device printing process. According to the PVC-gel artificial muscle integrated printing method,a 3D printing technology is combined with the fully flexible PVC-gel artificial muscles, the 3D printing technology is applied into an integrated preparation process of a PVC-gel electrode and a corelayer, rapid prototyping of structures of the fully flexible PVC-gel artificial muscles is realized, the cost of manufacturing the fully flexible PVC-gel structures is lowered, and application of thematerial in the fields such as medical treatment, aerospace, soft robots is expanded.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a PVC-gel artificial muscle integrated printing method. Background technique [0002] PVC gel (poly vinylchloride-ge1, referred to as PVC) is an electroactive polymer with high strain (above 13%), fast response, wide operating frequency, light weight, operating voltage between IPMC and DE, driving The advantages of high performance and the ability to realize two driving forms of bending and up and down vibrations have gradually been paid attention to by researchers and have been initially applied. [0003] Existing casting or lamination processes for preparing PVC actuators can only produce relatively simple structures, and existing PVC uses rigid electrodes such as copper foil, stainless steel mesh, and zinc electrodes, so it is difficult to make fully flexible actuators. Contents of the invention [0004] The technical problem to be solved by the present inve...
