摘要
以过硫酸铵为氧化剂,采用原位吸附聚合法,将苯胺聚合于纸浆纤维的微孔壁中以制造导电纸。系统地研究了掺杂酸种类、掺杂酸浓度、二次掺杂温度、二次掺杂时间及共掺杂等掺杂条件对导电纸性能的影响。研究表明,有机磺酸(对甲苯磺酸和磺基水杨酸)和硫酸的掺杂效果较好,掺杂酸浓度为0.6 mol/L,二次掺杂温度低于35℃和时间少于7.5 h时导电纸的表面电阻率较低。将对甲苯磺酸和硫酸共掺杂,二者的物质的量比为2∶1时,可获得最佳的掺杂效应。
In order to manufacture conductive paper, aniline was polymerized into the micro-pore wall of the pulp fther by in-situ adsorption polymeration process using ammonium persulfate as oxidant. The effects of different doping conditions on the performance of conductive paper including the kinds and concentrations of dopants, temperature and time of secondary doping and co-doping were studied in detail. The results showed that organic sulphonie acids （toluene-p-sulfonie acid and sulfosalicylie acid） and sulfuric acid were excellent dopants. The optimum concentration of the dopants was 0.6 mol/L. The optimum temperature and time of secondary doping were less than 35 ℃ and 7.5 hours. Higher temperature and longer time would not only lead to increase the surface resistivity, but also lead to the destruction of pulp fiber matrix. The optimum co-doping effect could be obtained when the mole ratio of toluene-p-sulfonie acid to sulfuric acid was 2：1.
