【摘要】 纳米带以其独特的性质,在光、电等领域有巨大的潜在的应用价值,从而引起科学家们的高度重视。光致变色材料广泛应用于信息存储、装饰和包装材料、信号显示等领域。采用静电纺丝技术,将光致变色纳米粒子掺入到高分子中制备无机-有机光致变色纳米带,是一个新颖的研究课题。本文将AgX水溶胶、AgX有机溶胶、双硫腙锌(Zn(HDz)2)分别掺入到聚乙烯醇(PVA)、聚甲基丙烯酸甲酯(PMMA)、聚乙烯吡咯烷酮(PVP)中利用溶胶-凝胶法配制成具有一定粘度的前驱体溶液,采用静电纺丝技术制备了AgX/PVA复合纳米带、AgX/PMMA复合纳米带、Zn(HDz)2/PVA复合纳米带及AgX/PVP复合纳米纤维。采用XRD、FTIR、SEM、UV-Vis等测试手段对其进行结构表征和性能测试。结果表明,所制备的AgX/PVA、Zn(HDz)2/PVA复合纳米带宽度为1~2μm,厚度为100nm;AgX/PMMA复合纳米带宽度为5~10μm,厚度为1μm;AgX/PVP复合纳米纤维直径为200nm。所制备的纳米复合材料都具有良好的光致变色性质。

【Abstract】 Nanoribbons have aroused much attention from many scientists due to their particular properties and greatly potential applications in light, electricity and so on. Photochromatic material can be used in information storage, decorative material, package material, signal display and other fields because of their unique characteristics. It is a novel research subject to insert photochromic nanoparticles into polymer to prepare inorganic compounds/polymer nanometer hybrid photochromic composite nanoribbons by electrospinning.In this disseration, sol-gel technique was employed to prepare the precusor solution with certain viscosity by mixing AgX hydrosol, AgX organosol, Zn(HDz)2 with PVA, PMMA, and PVP, respectively and prepared AgX/PVA composite nanoribbons, AgX/PMMA composite nanoribbons, Zn(HDz)2/PVA composite nanoribbons and AgX/PVP composite nanofibers using electrospinning technique. The samples were systematically characterized by XRD, FTIR, SEM, UV-Vis, et al. The results illustrate that the width of AgX/PVA, Zn(HDz)2/PVA composite nanoribbons are all in 1~2μm and the thickness is about 100nm; the width of AgX/PMMA composite nanoribbons are all in 5~10μm and the thickness is about 1μm; the diameter of AgX/PVP composite nanofibers are around 200nm. These samples which we have mentioned above all have excellent photochromism effect.
