▎ 摘　　要

NOVELTY - Antifouling film comprises a stimulus generating unit for generating a stimulus to a needle structure, where the needle structure is reversibly bent or tilted to remove the introduced contamination source. USE - Used as antifouling film. ADVANTAGE - The antifouling film periodically controls the external stimulus by the stimulus generating unit, thus fundamentally preventing the generation and proliferation of microorganisms by actively removing the biofilm accumulated due to prolonged exposure to contamination, thus it was confirmed that the biofilm removal efficiency was increased compared to the conventional antifouling film; and has increased durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing antifouling film, comprising providing needle structure and stimulus generating unit for generating stimulus to the needle structure.
