Microphase separation of block copolymers is a self-assembly process offering finely-tuned nm patterns in a large scale. Combined with inorganic components such as metal ions and nanoparticles, it is possible to create metal nanoarrays based on the block copolymer self-assembly by bestowing metal-interacting functionality to specific microdomains. We present the synthesis and characterization of a new block copolymer (BCP) system where one of the blocks contains a carboxylic acid as a functional group capable of interacting with metal ions. We have synthesized the target BCP by installing the carboxylic acid by postpolymerization modification, and characterized its microphase separation behavior by using small angle X-ray scattering (SAXS) and transmission electron microscopy (TEM). To the microphase separated surface metal ions were selectively loaded onto the modified block followed by plasma treatment to remove the polymer layer, resulting in a patterned metal array.
