【摘要】 作为印制电子技术的关键材料,导电油墨的开发与创新具有实际意义。为解决纯纳米银油墨在纸基上附着力差的问题,本文配置了可用于喷墨打印的树脂纳米银导电油墨,分析并讨论导电墨层的电导率和力学性能。首先,将纳米银和光固化丙烯酸树脂按照一定比例分散在有机溶剂中,并加入少量助剂配置得到适用于喷墨打印的导电油墨。然后,通过分析纯纳米银墨层不同烧结温度下的烧结情况,讨论了烧结温度对纳米银电阻率的影响,并讨论了纳米银-树脂油墨的导电性能。最后,对比了纯纳米银油墨与树脂纳米银油墨的力学稳定性能。结果表明,纳米银固含量为20%的纳米银油墨在烧结温度为170℃,烧结时间2分钟可得到电导率为2.72×105S/m的导电墨层,而含树脂的纳米银-树脂油墨可获得电导率为3.3×104S/m的导电墨层。光固化丙烯酸对提高油墨力学稳定性有积极作用,特别是抵抗垂直方向的作用力。更多还原

【Abstract】 Development and innovation researches of conductive ink have practical significance because conductive ink is a key material for printed electronic technology.To’ solve the poor-adhesion problem of pure nano-silver ink on a paper substrate,paper-based resin nano-silver conductive ink for ink-jet printing was produced by adding acrylic resin and photo-initiator into silver nano-colloids.The electrical conductivity and mechanical properties of the conductive ink layer were analyzed and discussed.Firstly,a certain proportion of the nano-silver and photo-curable acrylic resin were dispersed in an organic solvent,and a small amount of additives were added to obtain conductive ink suitable for ink jet printing.Then,different sintering conditions of pure nano-silver ink were analyzed to discuss the effects of sintering temperature on the nano-silver resistivity,and conductive property of resin nano-silver ink was discussed.Finally,the mechanical stability of pure nano-silver ink and resin nano-silver ink was compared.The results showed that the conductive ink containing 20%of the nano-silver obtained a conductivity of 2.72 × 105 S / m when sintered at 170 ℃ for two minutes,while the conductive ink containing resin obtained a conductivity of 3.3 × 104 S / m.The addition of acrylic resin has a positive effect on improving the mechanical stability,especially in the vertical direction of the resistance force.更多还原
