中文摘要：

采用液相化学还原法,以聚乙烯吡咯烷酮（PVP）、硝酸银（AgNO3）及水合肼（N2H4.H2O）制备银纳米粒子;以丙烯酸树脂/丙烯酸乳液为粘接料,将纳米银粉加入并辅以其他填料,制备水性导电油墨;最后将导电油墨涂覆在聚对苯二甲酸类（PET）薄膜表面成型。对银纳米粒子和油墨进行了X射线衍射（XRD）、透射电子显微镜（TEM）及扫描电子显微镜（SEM）等表征,研究了纳米银粉的添加量和热处理温度等对油墨导电性能和界面结合力的影响,结果表明：当纳米银粉质量分数为64.0%,热处理温度为150℃时,薄膜表面电阻达到0.9Ω/□,导电油墨与聚对苯二甲酸类（PET）基体的附着力达到美国材料与试验协会（ASTM）5B级,并具有良好的耐湿和耐温性。

英文摘要：

Acrylic resin/silver conductive inks have been prepared using synthesis of silver nanoparticles via a AgNO3 aqueous solution as a precursor and poly（vinylpyrrolidone）（PVP） as the capping agent.The resulting silver nanoparticles as conductive fillers were mixed with acrylic resin/acrylic emulsion as a bonding agent to form conductive inks.The silver nanoparticles and conductive inks were characterized by X-ray diffraction（XRD）,transmission electron microscopy（TEM） and scanning electron microscopy（SEM）,respectively.When the silver nanoparticle content was about 64.0% and sintering temperature was 150 ℃,the surface electrical resistance of the ink was 0.9 Ω/□.Cross-cutting tests showed that adhesion between the ink and polyethylene terephthalate（PET） films reached ASTM 5B.In addition,the conductive inks showed good wet resistance and thermostability.
