Synthesis of nanostructures using polymer self-assembly methods have gained widespread attention due to the multitude of possibilities they offer and their simple and cost-effective approaches. Self-assembly of block copolymers has been recognized as a promising means of creating functional nanostructures in both bulk and on surfaces. The nanostructures formed by block copolymers have been useful for their chemistries, morphology and dimensions. Block copolymers form micelles when dissolved in selective solvents. Several morphologies have been reported for micelles like spherical, cylindrical, and worm-like. Spherical micelles form an ordered array on surface under appropriate conditions of preparation and coating. Their orderly arrangement along with their dimensions offers a simple way of achieving high density nanoscale patterned surfaces. This presentation will highlight our recent work on the use of block copolymer micellar self-assembly as a novel platform to create functional interfaces. The development of a tool box consisting of micellar arrays with tunable micelle dimensions and array periodicities on surface and the application of micellar arrays for both its topography and chemistry will be discussed.
