▎ 摘  要

NOVELTY - The method involves preparing a non-metal conductive composite material. Flexible substrate material is utilized as a driver flexible layer and formed on a bottom plate of a three-dimensional (3D) printer. Shape memory polymer is utilized as printing material. An active deformation layer is formed. Prepared non-metal conductive composite material is uniformly coated on another side surface of the flexible substrate material. A conductive layer is dried, cured and formed for finishing manufacture of a driver. A prepared driver is placed in a constant temperature environment for heating for cooling to room temperature. External voltage of the driver is changed such that the driver is repeatedly switched between temporary shape and permanent shape for forming reversible bidirectional cyclic deformation. USE - Method for manufacturing a bidirectional deformation flexible intelligent driver based on four-dimensional (4D) printing. ADVANTAGE - The method enables ensuring simple manufacturing technique at low manufacturing cost, realizing different degree of memory change by changing the printing process parameter or activation voltage of the active layer, and ensuring recovery rate and response speed. DETAILED DESCRIPTION - The non-metal conductive composite material is mixture of polystyrene sulfonate solution, carbon nanotube solution, graphene oxide (GO) solution or MXene solution. Shape memory polymer is polylactic acid, acrylonitrile butadiene styrene and polyethylene terephthalate glycol. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a bidirectional deformation flexible intelligent driver. (Drawing includes non-English language text).
