中文摘要:
      目的 研究分散剂的含量对碳导电油墨导电性能和表面性能的影响。方法 以德谦W-920为分散剂, 采用单因素法, 保持碳导电油墨其他组分不变, 改变分散剂的配置比例, 制备不同组碳系导电油墨。最后通过SEM图表征墨膜的形貌。结果 不同含量的分散剂对导电油墨的性能产生一定差异。在其他条件一定的情况下, 随着分散剂比例的增加, 导电性先上升后下降。结论 分散剂的加入对导电油墨的性能起着重要作用, 当分散剂的质量分数达到7%时, 体积电阻率为3.01×10-2 Ω·m, 此时可以有效改善导电油墨的导电性和墨膜的规整性。
英文摘要:
      Objective To study the influence of the dispersant content on the conductivity and surface properties of carbon conductive ink. Methods In the experiments, the dispersant Deuchem W-920 was taken as an example, and the single-factor analysis strategy was used to prepare ink with different conductivity via changing the proportion of dispersant. At last, Scanning Electron Microscope (SEM) was used to characterize the morphology of the ink film. Results Different proportions of dispersant led to certain difference in the performance of conductive ink. In particular, when the other conditions were constant, with the increase of the dispersant proportion, the conductivity of conductive ink firstly increased and then decreased. Conclusion The addition of dispersant played an important role in the performance of conductive ink. When the proportion of dispersant reached 7%, the volume resistivity reached 3.01×10-2 Ω·m, which could improve the conductivity of the conductive ink as well as the regularity of the ink film.
