Thin layer surface templates were fabricated by spin coating two immiscible polymers onto a photoreactive substrate, followed by photoirradiation and removal of the unreacted polymer with solvent. Phase-separation occurs during the spin coating process and the separated structure was tethered onto the substrate surface by photoirradiation, to yield a thin surface pattern on the substrate. The surface patterns thus obtained were robust, applicable to large areas, and could be tuned at will by designing component polymers.
通过将两种不相溶的聚合物旋涂到光活性基底上,然后进行光照射并用溶剂去除未反应的聚合物,制备出薄层表面模板。在旋涂过程中会发生相分离,分离后的结构通过光照射被拴在基底表面,从而在基底上形成薄层表面图案。由此获得的表面图案坚固耐用,适用于大面积区域,并可通过设计成分聚合物随意调整。
