  Reduction/oxidation reagents have been found to be effective to chemically cure a sparse metal nanowire film into a fused metal nanostructured network through evidently a ripening type process. The resulting fused network can provide desirable low sheet resistances while maintaining good optical transparency. The transparent conductive films can be effectively applied as a single conductive ink or through sequential forming of a metal nanowire film with the subsequent addition of a fusing agent. The fused metal nanowire films can be effectively patterned, and the patterned films can be useful in devices, such as touch sensors.

  研究发现，还原/氧化试剂能有效地将稀疏的金属纳米线薄膜通过明显的熟化过程化学固化成熔融金属纳米结构网络。由此产生的熔融网络可以提供理想的低薄片电阻，同时保持良好的光学透明度。这种透明导电薄膜可作为单一导电墨水有效应用，也可通过连续形成金属纳米线薄膜并随后添加熔融剂有效应用。熔融金属纳米线薄膜可以有效地图案化，图案化薄膜可用于触摸传感器等设备。

  Provided is a composition for bonding, in particular, a composition for bonding which contains metal particles, said composition for bonding enabling the achievement of high bonding strength by bonding at a relatively low temperature and having such heat resistance that a decrease in the bonding strength does not easily occur due to &composition, deterioration or the like of a resin component when service temperature is increased. This composition for bonding is characterized by containing inorganic particles and an organic material that contains an amine and/or a carboxylic acid and adheres to at least a part of the surface of each inorganic particle, and is also characterized in that the weight loss rate when heated from room temperature to 200°c. is 33-69% and the weight loss rate when heated from 200° c. to 300° c. is 24-50% as determined by thermal analysis.
