采用静电纺丝技术制备Zn(HDz)_2/PVA复合纳米带,用XRD、SEM、FTIR、UV-Vis等技术对样品进行了表征。XRD分析表明,该复合纳米带为无定型的。FTIR分析表明,所制备的Zn(HDz)_2/PVA复合纳米带的主要成分为聚乙烯醇(PVA)。通过SEM照片,可以看出Zn(HDz)_2/PVA复合纳米带表面光滑,尺寸均一,纳米带的长度可达到1cm,且宽厚比较大,厚度约为100~200nm,平均宽度约为1.8μm。UV-Vis分析表明,Zn(HDz)_2/PVA复合纳米带具有良好的光致变色性质。
Zn (HDz) _2 / PVA composite nanobelts were prepared by electrospinning technique. The samples were characterized by XRD, SEM, FTIR and UV-Vis. XRD analysis shows that the composite nanoribbons are amorphous. FTIR analysis showed that the main component of Zn (HDz) _2 / PVA composite nanobelts prepared was polyvinyl alcohol (PVA). The SEM images show that the surface of Zn (HDz) _2 / PVA composite nanoribbons is smooth and uniform in size. The length of the nanoribbons can be up to 1cm, and the thickness of the Zn (HDz) _2 / PVA composite nanoribbons is about 100-200nm with the average width of about 1.8μm. UV-Vis analysis showed that Zn (HDz) _2 / PVA composite nanoribbons have good photochromic properties.
