通过加入石墨(GP)和碳纤维(CF),采用传统纸张成形技术可生产出电导率可以调整和机械性能良好的GP、CF和GP/CF纤维素纤维导电纸。羧甲基纤维素(CMC)作为CF的分散剂加入到纸料中,不管导电相的组成如何,得到的导电纸都较柔软且易于处理,没有肉眼可见的匀度缺陷。本实验得到的GP/CF纤维素纤维导电纸的电导率高达964S/m,比先前报道的纤维素纤维导电纸的电导率至少高44%。此外,从一次性及可循环使用的角度看,采用该方法生产的导电纸成本低且易于规模化生产。
GP, CF and GP / CF Cellulose fiber conductive paper with adjustable conductivity and good mechanical properties can be produced by conventional paper forming techniques by adding graphite (GP) and carbon fiber (CF). Carboxymethylcellulose (CMC) is added to the stock as a dispersant for CF. The resulting conductive paper is softer and easier to handle, with no visible defects in the texture, regardless of the composition of the conductive phase. The conductivity of the GP / CF cellulose fiber conductive paper obtained in this experiment is as high as 964 S / m, which is at least 44% higher than the previously reported conductivity of the cellulose fiber conductive paper. In addition, the conductive paper produced by this method is low-cost and easy to manufacture on a large scale from the viewpoint of disposableness and recyclability.
