▎ 摘　　要

NOVELTY - The immersion active adjusting device has a wetting adjusting structure (300) set on the surface of a base structure (100) and connected with a driving structure. The wetting adjusting structure comprises a column and a head connected to the end portion of the column. Multiple branches of the head are folded or separated to deform under the stimulation of driving structure through stimulation signal, so as to realize the adjustment of hydrophobic or hydrophilic characteristic. The material of the driving structure is selected from a group consisting of polypyrrole, polylacticacid/carbon black, polylactic acid/graphene. USE - Immersion active adjusting device for preparation of wetting interface material for use in micro-fluidic control, oil-water separation and intelligent sensing field. ADVANTAGE - The device can realize the requirement of different hydrophobic or hydrophilic degree by controlling the deformation of the micro-structure, while meeting the requirements of different functionality, responsiveness and response action. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of immersion active adjusting device. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the immersion active adjusting device.
