不同的碳系材料對導電碳漿之性能產生不同的影響，研究不同類型的碳系材料對導電碳漿電性能、硬度、附著力之影響。通過實驗證明了加入石墨烯在石墨中，可以使導電碳漿具有優良的硬度、附著力，以及具有較低的電阻率可以至5ⅹ10-1 Ω•cm. ;With the rapid development of technology, many researches are putting more emphasis on the conductive carbon ink. Conductive carbon ink is kind of significant functional conducting material which is usually used in membrane switch and printed circuit board. Conductive carbon ink has excellent electrical conductivity and mechanical properties, including hardness and adhesiveness. The conductive phase and resin binder phase are the most influential ingredients in the ink.
The preparation and manufacturing of conductive carbon ink was studied in this thesis, it can be seen from experiments that the optimum composition of conductive phase is 60 wt. %, it has the suitable viscosity to do screen printing。The effect of the curing condition on electrical property also studied at the same time. It can be found that the optimum conditions of curing temperature is 180 ℃, and the optimum curing time is 60 min. Also use the three-roll mills to make the particle size of the carbon ink decreased and has lower resistivity.
The effect of different carbon material on electrical conductivity and mechanical properties of carbon ink was studied in this thesis. Results show that the graphene/ graphite ink has excellent hardness, adhesiveness and lower resistivity of 3.3ⅹ10-1 Ω • cm
