摘要： We demonstrate a simple, rapid, cost-effective and robust approach to modify the surface of a solid substrate, based on a UV-irradiated film of a general plastic polymer. Thin films of homopolymer polystyrene (PS) of controlled thickness were spin-coated on diverse metal, semiconductor and polymeric surfaces. Specific surface chemistry was tuned with UV irradiation in air (UVIA); interactions at the PS/substrate interface were enhanced with UV irradiation in nitrogen (UVIN). Oxidized and cross-linked PS served as a neutral surface on various metal, quartz, semiconductor and polymeric substrates to induce perpendicularly oriented cylinders or lamellae in a self-assembled block copolymer. 其他題名： Soft Matter 出版者： England 出版日期： 2016-01-01 出處： Soft matter, 2016-01, Vol.12 (11), p.2923-2931 識別號： ISSN: 1744-683X 識別號： ISSN: 1744-6848 識別號： EISSN: 1744-6848 識別號： DOI: 10.1039/C5SM02605A 識別號： PMID: 26890311
