摘要
利用墨汁中碳纳米粒为增强体,以流延法制备墨汁/壳聚糖复合膜。采用扫描电子显微镜(SEM)对复合膜的结构进行了表征,研究不同的墨汁加入量对墨汁/壳聚糖复合膜力学、耐水以及光透过率等性能的影响。结果表明低含量墨汁中碳纳米粒可均匀分散在壳聚糖基体中。与纯壳聚糖膜相比,加入墨汁后的复合膜的力学性能和耐水性能得到了明显的提高。复合膜的光透过率随着复合膜中墨汁含量的增加急剧下降,具有非常优异的光阻隔性能。
A series of nanocomposite films were prepared by solution casting method with Chinese ink introducing into chitosan matrix as nanofiller.The obtained composite films were characterized by scanning electron microscopy,ultraviolet-visible spectroscopy(UV-vis).The results indicated that the mechanical properties and water resistance of composite films filled with CI were improved greatly compared with the pure chitosan film.In addition,the resultant composites films with high loading CI can almost completely block the whole UV-vis region(200-800 nm),which is beneficial for their application as optical-shield materials.
