| 目的 探究提升碳系水性导电油墨导电性能的方法，主要研究分散剂和树脂的含量对碳系水性导电油墨导电性能的影响。方法 使用W−190分散剂和水性丙烯酸树脂，采用双因素法，保持分散剂和树脂的总质量在油墨中的占比固定，且其他组分在油墨中的占比也不变，通过改变分散剂与树脂之间的比例，制备多组碳系水性电热油墨。通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)观察各组碳系水性导电油墨，测试油墨的黏度、方阻，探究导电油墨的形貌和导电性。结果 通过改变分散剂与树脂的质量比值，会对导电油墨的导电性能产生较大影响。在其他条件一定的情况下，随着分散剂与树脂的质量比值的增加，碳系水性导电油墨的导电性呈先降低再升高的趋势。结论 分散剂与树脂的质量比对导电油墨的导电性具有较大影响，当分散剂与树脂的质量比为2.5∶1时，在分散研磨60 min后，碳系水性导电油墨的黏度最大值为11.1 Pa.s，方阻最小值为4.3 Ω/□，此时导电性相对最佳。 |

| The work aims to explore the method of improving the conductivity of carbon-based water-based conductive ink and mainly study the effect of the content of dispersant and resin on the conductivity of carbon-based water-based conductive ink. W-190 dispersant and water-based acrylic resin were used. The two-factor method was adopted to keep the total mass ratio of the dispersant and the resin constant, and the mass ratio of other components in the ink also remained unchanged. By changing the ratio between the dispersant and the resin, multiple sets of carbon-based water-based electric heating inks were prepared. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to observe the carbon water-based conductive ink in each group, and the viscosity and square resistance of the ink were tested to explore the morphology and electrical conductivity of the conductive ink. The change of mass ratio of dispersant and resin had a certain effect on the conductivity of conductive ink. When other conditions remained unchanged, as the ratio of dispersant to resin increased, the conductivity of the carbon-based water-based conductive ink firstly decreased and then increased. The ratio of dispersant to resin has an important effect on the conductivity of conductive ink. When the mass ratio of dispersant to resin is 2.5∶1, after dispersion and grinding for 60 min, the maximum viscosity of carbon-based water-based conductive ink is 11.1 Pa.s, and the minimum square resistance is 4.3 Ω/□. At this time, the conductivity is the best. |
