Embodiment

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

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

[0061] 2) Configuration of electrode printing ink

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

[0063] 3) Integrated direct writing printing process

[0064] ①Put the PVC ink of the core lay...

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, PVC for short) is an electroactive polymer with high strain (more than 13%), fast response speed, wide working frequency, light weight, working voltage between IPMC and DE, driving With high performance, it can realize the advantages of bending and vertical vibration driving modes, etc., which has gradually been paid attention to by researchers and preliminary applications have been carried out. [0003] The existing process for preparing PVC actuators by cast film or laminated layers can only prepare relatively simple structures, and the existing PVC uses copper foil, stainless steel mesh, zinc electrodes and other rigid electrodes, so it is difficult to make a fully flexible actuator. Summary of the invention [0004] The technical problem to be solved...
