Abstract:	以一個快速、簡單、有效的方法，用紫外光照射一般高分子聚合物以進行固體表面的改質。我們使用聚苯乙烯(Polystyrene,PS)旋鍍在各種不同的金屬、半導體、聚合物的表面上，利用紫外光在空氣下照射聚苯乙烯膜，以氧化而改變聚苯乙烯的化學性質。之後將其在氮氣下照光以進行交聯，增加聚苯乙烯強度，並使聚苯乙烯膜與基材的交互作用加強。改變聚苯乙烯膜性質，以形成嵌段共聚物的中性表面，並讓其可以在金屬、半導體、聚合物的表面形成垂直柱狀、板狀的自組裝結構。;We demonstrate a simple, rapid, cost-effective and robust approach to modify a 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 became 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.
