Block copolymer can self-assemble into a range of well-defined, ordered nanostructures including spheres, cylinders, lamellae and double gyroids, depending on the relative volume fraction of the constituent polymers. Cylinder-forming block copolymers, with the cylinders oriented normal to the surface, are attractive as templates for the formation of ordered arrays of domains with high aspect ratio. In this work, two cylinder forming block copolymer (PS-b-PEO and PS-b-PVP) were mixed together and coated on the silicon wafers. Several type of nanoparticles were incorporated into microdomains selectively. To control the orientation and ordering solvent annealing were carried out. Well-controlled ordered structures were obtained and selective functionalization by nanoparticles was achieved along the nanostructure of block copolymer blend films. The characterization of films were performed by AFM, TEM and GISAXS. Same strategy was applied to the triblock copolymer (PS-P2VP-PEO) system. |
