1采用铜导电油墨在改性柔性基材上实现喷墨印刷显示文摘本文采用铜导电油墨在聚酰亚胺(PI)薄膜上进行喷墨印刷形成铜导电层,并研究基于铜络合物的铜导电油墨与柔性基材的相关性。本研究首先采用氧等离子体对PI薄膜表面进行改性,以测试接触角来表征改性前后薄膜表面性能的变化。通过优化等离子体反应参数使接触角降低。再利用喷墨印刷在改性前后PI薄膜上沉积铜导线,在200℃氢气环境下进行热处理,印制铜线发生烧结而收缩。采用光学显微镜(OM)、场发射扫描电子显微镜(FESEM)、X射线衍射(XRD)、非接触式三维轮廓仪和四点探针分析铜导线形状、微观结构、晶体结构及电导率。结果表明,经氧等离子体改性的PI基材上可成功沉积具有纯铜相的连续铜导线且具有良好的烧结微观结构,同时确定了铜导电油墨与基材表面性能的相关性。GOO Yongsung LEE Youngin KIM Namwoo LEE Kunjae YOO Bongyoung HONG Sungjei KIM Joong-do CHOA Yongho 王晓芳 2010中国印刷与包装研究2010,,5:4
2Influence of potassium pyrophosphate in electrolyte on coated layer of AZ91 Mg alloy formed by plasma electrolytic oxidation显示文摘The effect of potassium pyrophosphate in the electrolyte on plasma electrolytic oxidation(PEO) process for AZ91 Mg alloy was investigated.The morphologies and chemical compositions of the coating layer on the AZ91 Mg alloy were evaluated and corrosion resistance was also estimated by potentiodynamic polarization analysis.The coating layer on AZ91 Mg alloy coated from the Bath 2 containing 0.03 mol/L of potassium pyrophosphate for 360 s exhibited considerably dense structure and contained 11%-18%(mass fraction) of phosphorous.The higher content of phosphorous of coating layer coated from Bath 2 could be detected at the bottom of oxide layer,which strongly implied that the phosphorous ion might be concentrated at the barrier layer.Corrosion potential of coating layer of AZ91 Mg alloy increased and corrosion current density decreased with increasing the concentration of potassium pyrophosphate.The polarization resistance(Rp) of coating layer of AZ91 Mg alloy coated from Bath 2 was 4.65×107 Ω/cm2,which was higher than that(Rp=3.56×104 Ω/cm2) of the sample coated from electrolyte without potassium pyrophosphate.The coating layer coated from Bath 2 containing 0.03 mol/L potassium pyrophosphate exhibited the best corrosion resistance.Jin-Young CHO Duck-Young HWANG Dong-H eon LEE Bongyoung YOO Dong-Hyuk SHIN 2009中国有色金属学会会刊:英文版2009,19,4:3
3Characterization of plasma electrolytic oxide formed on AZ91 Mg alloy in KMnO_4 electrolyte显示文摘The aim of this work is to investigate microstructure,corrosion resistance characteristics and nanohardness of the oxide layer on AZ91 Mg alloy by applying different voltage with KMnO4 contained solution.There are lots of closed pores that are filled with another oxide compound compared with the typical surface morphology with pore coated until 350 V of coating voltage.The thickness of oxide layer increases with increasing coating voltage.The oxide layer formed on AZ91 Mg alloy in electrolyte with potassium permanganate consists of MgO and Mn2O3.Corrosion potential of the oxide layer on AZ91 Mg alloy obtained at different plasma electrolytic oxidation(PEO) reaction stages increases with increasing coating voltage.The corrosion resistance of AZ91 Mg alloy depends on the existence of the manganese oxide in the oxide layer.The inner barrier layer composed of the MgO and Mn2O3 may serve as diffusion barrier to enhance the corrosion resistance and may partially explain the excellent anti-corrosion performance in corrosion test.Nanohardness values increase with increasing coating voltage.The increase in the nanohardness may be due to the effect of manganese oxide in the oxide layer on AZ91 Mg alloy coated from electrolyte containing KMnO4.Duck-Young HWANG Ki-Ryong SHIN Bongyoung YOO Dong-Heon LEE Deok-Yong PARK Dong-Hyuk SHIN 2009中国有色金属学会会刊:英文版2009,19,4:2
