Effects of Molecular Weight on Orientation of Block Copolymer Thin Films |
| 초록 |
The effect of molecular weight on the orientation of block copolymer thin films was studied with optical microscopy (OM) and atomic force microscopy (AFM). Polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) with lamellar and cylindrical structure were spin coated on phenylundecyltrichlorosilane (PUTS) deposited substrates and annealed at 180℃ in vacuum. According to the molecular weights of PS-b-PMMA, the orientation were changed from parallel to perpendicular. The molecular weight of PS-b-PMMA is relatively small, parallel orientation was formed, in contrast, perpendicular orientation was occurred on relatively high molecular weights PS-b-PMMA for both lamellar and cylindrical block copolymer. From these results, the molecular weight or degree of polymerization is important to determine the orientation of block copolymer thin films as well as surface morphology. |
