中文摘要:
      采用饱和聚酯树脂作为导电油墨的有机相,研究了饱和树脂对该导电油墨性能的影响,通过光学显微镜、SEM观察了印刷膜层形貌图案,利用流变仪,分析了导电油墨的流平性能,利用四探针测试仪,厚度计及百格法研究了导电油墨的导电性及附着力性能。结果表明,饱和聚酯树脂作为有机相制备的导电油墨具有良好的印刷平整性和致密性,玻璃化温度高的饱和聚酯调制的导电油墨硬度高、电阻低、附着力弱,玻璃化温度低的饱和聚酯调制的导电油墨硬度低、电阻高、附着力强,调整导电油墨配方中不同玻璃化转移温度的树脂的比例,可提高导电油墨的综合性能。玻璃转化温度高的树脂用量:玻璃转化温度低的树脂用量=4:1时,导电油墨综合性能最好;在该配方中添加有机膨润土会使导电油墨室温储存后性能下降。
英文摘要:
      Using saturated polyester resin as organic phase of conductive ink, the effect of saturated resin on the performance of conductive ink was studied. The morphology pattern of printing film was observed by optical microscope and SEM. The leveling performance of conductive ink was analyzed by rheometer. The conductivity was studied by four-probe tester, thickness gauge .Adhesion of ink was studied by Berger method. The results show that the saturated polyester resin as organic phase has good printing smoothness and compactness. The saturated polyester-based conductive ink with high glass transition temperature has high hardness, low resistance and weak adhesion. The saturated polyester-based conductive ink with low glass transition temperature has low hardness, high resistance and adhesion. The comprehensive properties of conductive ink can be improved by adjusting the proportion of resins with different glass transition temperatures in the content of conductive ink. When the ratio of the amount of resin with high glass transition temperature: the amount of resin with low glass transition temperature resins is 4:1, the comprehensive properties of conductive ink are the best. In addition The addition of organobentonite in conductive ink will reduce the performance of conductive ink after storage at room temperature.
