近红外聚乙烯醇荧光高分子材料的制备及性能
Preparation and Properties of Near Infrared Polyvinyl Alcohol Fluorescent Polymer Materials
摘要
Abstract
Near-infrared fluorescence squaraine/polyvinyl alcohol ( PVA ) binary and squaraine/hydrophilic graphene/PVA ternary polymers with stronger fluorescence ( 660 ～665 nm ) intensity , photostability and thermostability were designed and synthesized from a squaraine dye , water soluble graphene and PVA . Compared to those in water , the maximum UV-Vis absorption and fluorescence wavelengths of the squaraine in PVA showed red shifts , and the fluorescence intensity and photostability were significantly enhanced .The presence of the graphene improved the photostability and thermostability of the material .关键词
