Abstract The self‐assembly of silver nanowires (AgNWs) with a high aspect ratio is highly desirable for practical applications; however, several challenges still exist. Herein, non‐contact, simple, large‐scale, micro‐domain photo‐alignment technology proposed to align AgNWs in liquid crystal polymer (LCP) film, resulting order parameter (above 0.9). are precisely controlled have planar alignment and twisted nematic structures micro‐multi‐domains. AgNW/LCP precursor frozen shape the film via ultraviolet crosslinking, allowing it be easily peeled off transferred various flexible other functional substrates. aligned can used improve mechanical properties LCP films, as they exhibit elongation‐at‐break strength‐at‐break. also further programmed by micro‐multi‐domain use wearable devices.
