实际纸基电子产品的创建需要在纸基板上制造导电银轨道的安全导电性。探讨了各种纸张性能，以获得与印刷电路质量密切相关的关键参数。在四种基材（照片质量喷墨纸、无光泽型喷墨纸、涂布胶版纸和未涂布实验室片材）之间，用基于十四烷的银纳米颗粒油墨喷墨印刷的银轨迹的电阻的比较暗示了孔径、孔隙率、表面粗糙度和表面能的重要性。纸张表面层的孔隙尺寸小，孔隙率高。高导电性，窄银轨道，因为快速吸收油墨，如照片质量的喷墨纸。表面粗糙度以导电性为代价诱导了对剥离力的高抗性，并且这种剥离抗性的改善被认为是由于落入存在于粗糙纸表面上的凹痕中的银纳米颗粒油墨的锚效应而实现的。通过控制纸张的表面能，银轨迹的宽度显著减小。这种趋势是显著的，特别是对于未涂覆的实验室片材，因此成功地提高了银轨道的导电性。(C)2013 Elsevier B.V.保留所有权利。
The creation of practical paper-based electronics requires secured conductivity with conductive silver tracks fabricated on a paper substrate. Various paper properties were explored for obtaining the key parameters intimately related to printed circuit qualities. A comparison of the resistance of silver tracks printed by ink-jet with a tetradecane-based ink of silver nanoparticles among four substrates photo-quality ink-jet paper, matte-type ink-jet paper, coated offset paper, and uncoated laboratory sheets implied the importance of pore size, porosity, surface roughness, and surface energy. Paper surface layers with small pore sizes and high porosities produced.highly conductive, narrow silver tracks because of quick ink absorption, as observed in the photo-quality ink-jet paper. The surface roughness induced a high resistance to peel-off force at the expense of conductivity, and this improvement in the peel-off resistance is considered to be achieved because of the anchor effect of silver nanoparticle inks which fell into dents present on the rough paper surfaces. The widths of the silver tracks were significantly reduced by controlling the surface energies of the paper sheets. This tendency was remarkable, especially for uncoated laboratory sheets, and thus the conductivities of the silver tracks were successfully improved. (C) 2013 Elsevier B.V. All rights reserved.
