| 目的 探究一锅法制备“点、线、面”-炭黑/多壁碳纳米管/石墨烯三维立体导电网络碳系水性油墨的影响因素及其在柔性电发热器件中的应用。方法 通过单因素实验法，对碳系浆料的研磨时间、油墨的颜基比及油墨厚度、柔性电发热器件面积、电压对电发热器件发热性能的影响等因素进行探讨，从而确定油墨最佳配比和柔性电发热器件的制备条件。结果 当研磨时间为5.5 h、油墨颜基比为2.5∶1.0、丝网印刷层数为2时，油墨最低电阻率为2.813 Ω.cm，柔性电发热器件经500次弯曲折叠后电阻变化率<3%。当外接电压为12 V的安全电压时，仅需20 s左右便可达到稳定温度170 ℃。结论 通过搭建三维立体导电网络以及确定适宜的研磨时间、油墨的颜基比和丝网印刷层数，可在一定程度上减少导电颗粒空隙，降低渗流阈值，提高油墨的导电性。这一碳系导电油墨为大规模生产柔性电子器件提供了新的技术路径和支持。 |

| The work aims to study the one-pot preparation process of point, line, plane -carbon black/multi-walled carbon nanotubes/graphene three-dimensional conductive network carbon-based aqueous ink and its application in flexible electric heating devices. The optimal pigment-binder ratios and the preparation process of flexible electric heating devices were determined by exploring the factors such as the grinding time of the carbon-based slurry, the pigment-to-base ratio of the ink and the thickness of the ink, the area of the flexible electric heating device, and the effect of different voltages on the heating performance of the electric heating device through the one-factor-variable method. When the grinding time was 5.5 h, the pigment-binder ratio was 2.5∶1.0, and the screen printing layers of the carbon-based conductive ink were 2, the lowest resistivity of the ink was 2.813 Ω.cm, and the resistance change rate of the flexible electric heating device was less than 3% after 500 times of bending and folding. When the external voltage was 12 V safety voltage, it only took about 20 s to reach a stable temperature of 170 ℃. The three-dimensional conductive network and the appropriate grinding time, pigment ratio and number of screen printing layers reduce the conductive particle voids to a certain extent, lower the percolation threshold and improve the conductivity of the ink. This carbon-based conductive ink provides a new technological path and support for mass production of flexible electronic devices. |
