技術說明

【中文】 一種固態光子晶體之製備方法，將一聚苯乙烯-聚乙烯吡啶共聚物溶於一含氯溶 劑後塗佈成一初始薄膜，該共聚物會自組裝成具週期性的三維網狀結構，接著將 該初始薄膜浸泡於一極性溶劑中膨潤該共聚物，以形成一凝膠態薄膜，最後乾燥 該凝膠態薄膜以形成一固態光子晶體，於該極性溶劑揮發過程中，聚乙烯吡啶鏈 段會轉變為玻璃態並於該凝膠態薄膜表面形成一玻璃態薄層，使得該共聚物之 該三維網狀結構保留近似於凝膠態狀態的週期尺寸。 【英文】 A method for fabricating solid photonic crystals includes the steps: a PS-PVP copolymer is dissolved in a chloride-containing solvent and is coated as an initial film; the copolymer self-assembles into 3D ordered network-structured morphology with periodicity; the copolymer in the initial film is swollen in a polar solvent to form a solvated film; the solvated film is dried to form a solid photonic crystal. During evaporation of the polar solvent, the PVP block of the copolymer becomes glassy and forms a thin glassy layer on the surface of the solvated film such that the 3D network structure of the copolymer in solvated state can be trapped into the solid photonic crystal revealing similar periodicity and dimension to that in solvated state.
