荧光碳纳米粒子与纸张的相互作用及分析特性研究

The study of interaction between fluorescent carbon nanoparticles and paper materials and its analytical application

在研究荧光碳纳米粒子与纸质材料相互作用的基础上,考察了荧光碳纳米粒子从纸质材料表面的洗脱去除方法以及残留荧光碳纳米粒子对纸质材料的性能如抗老化能力、机械强度等的影响,提出了一种可基于荧光碳纳米粒子原位、无损传感纸张表面pH的新方法,并测定了纸质文物表面的pH。

The interaction of the fluorescent carbon nanoparticles with paper-based materials was investigated by the fluorescent microscopy, and the removing of carbon nanoparticles from paper surface, the effect of retained carbon nanoparticles on the aging resistance as well as mechanical strength of paper material were studied. Our results showed that the synthesized fluorescent carbon nanoparticles could in-situ, nondestructively sense the surface acidity of paper-based materials. This new fluorescent carbon nanoparticles. finding may open a new way for analytical application of the
