摘要: 以水合肼(N2H4·H2O)为还原剂,聚乙烯吡咯烷酮(PVP)为保护剂,通过液相还原硝酸银溶液制备纳米银粉。以制备的银粉纳米粒子为导电填料,以水性聚氨酯丙烯酸树脂为连接料,以乙醇和去离子水为溶剂,并辅以其他助剂,制备出水性UV导电油墨。经TEM表征和马尔文粒度仪测试,纳米银粉的平均粒径为5nm。最后用300目的涤纶丝网版在铜版纸基上印刷,在105℃下处理15min,用UV固化干燥后,测试墨层的电导率和附着力,并用SEM表征了墨层烧结后的形貌特征,结果表明:研制的用于柔性基材的水性UV导电油墨经190℃低温烧结2min,电导率为1.84×104S/m,经3M胶带撕拉,墨层不发生脱落现象。

Abstract: Nano-silver was prepared by chemical reduction method in silver nitrate solutions, using N2H4·H2O as deoxidizer and polyvinylpyrrolidone (PVP) as polymeric protective agent. Prepared silver nanoparticles was added as filler, aqueous polyurethane acrylic resin was added as binder, ethanol and deionized water were added as the diluent, and a water-based UV conductive ink was prepared with other additives. The average diameter of the nano silver is 5 nm by SEM characterization and nano-size analyzer. Then prepared ink was printed on a coated paper with polyester screen plate in 300 mesh, processing under 105℃ for 15min, the conductivity of the ink and adhesion were tested after UV cured, the results show that water-based UV conductive ink for flexible substrates was sintered for 2 min at 190℃, and the conductivity was 1.84 × 104S/m. There was no deinking occurred after tearing off with 3M adhesive tape.

Key words: liquid phase, reduction, nanoparticles, solvents, water-based UV conductive ink
