Abstract
Disclosed is a method for fabrication of a patterned micro-architectural array by directional photo-fluidization of a polymer, which includes a process for formation of a micro-architectural array, the method comprising preparing a micro-fluidic device by bonding a rubber mold having a micro-pattern to a substrate, introducing a polymer solution to the micro-fluidic device, drying the polymer to form a polymer line array corresponding to a pattern of a micro-fluidic tube, inducing directional photo-fluidization by light radiation to control shape and size of the micro-architectural array, and applying metal to the polymer array having controlled structure by directional photo-fluidization then selectively removing the polymer, in order to transfer the shape of the polymer onto the micro-architectural array. Precisely controlled and various micro-architectures having different sizes as well as regular alignment shapes may be fabricated in large scale and parallel mode by transferring the foregoing controlled template onto the architecture.
