METHOD FOR NANO-STRUCTURE FORMATION OF BLOCK COPOLYMER BY BLENDING WITH HOMOPOLYMERS

摘要

A method for forming a polystyrene-polypentyl methacrylate block copolymer having a nanostructure is provided to improve the time efficiency and labor efficiency by using a simple process that allows control of a range of temperatures where the nanostructure is formed. A method for forming a polystyrene-polypentyl methacrylate block copolymer having a nanostructure at 100-250 deg.C comprises a step of adding and blending polystyrene to and with a polystyrene-polypentyl methacrylate block copolymer forming a homogeneous phase. The polystyrene-polypentyl methacrylate block copolymer forming a homogeneous phase has a molecular weight of 46,000-50,000. The polystyrene added to the polystyrene-polypentyl methacrylate block copolymer forming a homogeneous phase has a molecular weight of 12,500-50,000.
