In this work, we seek to find out new yet simple way to nanofabrication via sequential applications of two different self-assembling materials. Block copolymer, one class of self-assembling materials, spontaneously self-assemble into various structures on the nanometer scale. Very recently, several strategies to direct the self-assembly of block copolymers have been proposed for effective control of their nanostructures. Colloidal particles are another type of self-assembling materials, which produces highly ordered colloidal crystals via self-assembly driven by capillary force or convection flow. Here, colloidal particles are first deposited on the substrate to form colloidal crystal, and then block copolymers are coated on colloidal crystals so that they are able to guide block copolymer self-assembly. It was found that combination of two self-assembling materials and variation of size of templates lead to the morphological change of block copolymers on the substrate. |
