Cu–Ag complex inks are developed for printing conductive tracks of low cost, high stability, and high conductivity on heat-sensitive substrates such as polyethylene terephthalate (PET) substrates. The inks show an obvious self-catalyzed characteristic due to the in situ formation of fresh metal nanoparticles which promote rapid decomposition and sintering of the inks at a low temperature below 100 °C. The temperature is 40–60 °C lower than those of general Cu complex inks and 100–120 °C lower than those of general Cu/Ag particle inks. Highly conductive Cu–Ag tracks of 2.80 × 10−5 Ω cm and 6.40 × 10−5 Ω cm have been easily realized at 100 °C and 80 °C, respectively. In addition, the printed Cu-based tracks not only show high oxidation resistance at high temperatures of up to 140 °C (the maximum tolerable temperature of current PET substrate) but also show excellent stability at high humidity of 85% because of the very uniform Cu–Ag hybrid structure. The printable tracks exhibit great potential application in various wearable devices fabricated on textiles, papers, and other heat-sensitive substrates.

自催化铜-银复合油墨，可在低于100°C的低温下低成本制造高度抗氧化和导电的铜-银混合油墨†
铜-银复合油墨被开发用于在热敏性基材（例如聚对苯二甲酸乙二酯（PET）基材）上印刷低成本，高稳定性和高导电性的导电迹线。油墨显示出明显的自催化特性，这是由于新鲜金属纳米颗粒的原位形成，促进了在低于100°C的低温下油墨的快速分解和烧结。温度比普通铜复合油墨低40–60°C，比普通铜/银颗粒油墨低100–120°C。2.80×10 -5Ωcm和6.40×10 -5的高导电性Cu-Ag轨道分别在100°C和80°C时容易实现Ωcm。此外，印刷的铜基印制线不仅在高达140°C（当前PET基材的最高容许温度）的高温下显示出高抗氧化性，而且由于其非常均匀的特性，在高湿度（85％）下也显示出优异的稳定性。 Cu-Ag杂化结构。可打印轨道在纺织品，纸张和其他热敏基材上制造的各种可穿戴设备中显示出巨大的潜在应用前景。
