摘　　要：通过两相界面反应制备出小尺寸银纳米颗粒,用喷墨打印技术和热处理工艺在柔性PET基材表面制备导电薄膜。用紫外-可见光吸收光谱、透射电镜和能谱研究了银颗粒粒径、微结构和成分,结果表明所合成的颗粒为多晶结构,粒径为2～5nm。用扫描电镜和四探针薄膜电阻率测量法研究了热处理温度、时间与薄膜形貌、电阻率之间的关系,结果表明柔性PET塑料表面的银颗粒在150℃条件下处理30min,可获得表面平整、无明显裂纹、电阻率～6.4μΩ.cm的导电薄膜。Silver nanopartieles were synthesized by the interfacial reaction method. The nanopartieles with diameter 2 ～ 5nm were characterized by UV-Vis absorption spectroscopy, TEM and EDX, The silver conducting films on polyethylene terephthalate （PET） substrates were fabricated by ink-jet technique using silver nanoparticle inks followed by thermal-annealing. The influences of the annealing temperature and time on the morphology and resistivity of the films were investigated. The result shows that the silver films on the PET substrates with resistivity of ～6.4μΩ·cm cm can be achieved at the annealing temperature of 150℃ for 30min.
