报道了一种利用聚二甲基硅氧烷(PDMS)印章的金属转移和纳米压印光刻技术在聚对苯二甲酸乙二酯(PET)基片上制作的半透明纳米网状铜电极。通过使用高模数的PDMS印章来复制纳米级的致密网状图案。研究发现，要将铜网状结构从PDMS印章转移到PET基板上，需要30磅/平方英寸的均匀压力和100℃的温度。制备的半透明铜电极在可见光区具有较高的透过率和良好的导电性。结果表明，减小网纹线宽可提高透过率，平均透过率可达75%。在柔性衬底上制作了有机电致发光二极管，展示了半透明铜电极作为透明导电电极的潜在用途。(C)2007年美国真空协会。
A semitransparent nanomesh Cu electrode on a polyethylene terephthalate (PET) substrate using metal transfer from a polydimethylsiloxane (PDMS) stamp and nanoimprint lithography is reported. A nanoscale dense mesh pattern is replicated by using a high modulus PDMS stamp. It is found that a uniform pressure of 30 psi and a temperature of 100 degrees C are needed for the transfer of the Cu mesh structure from the PDMS stamp onto the PET substrate. A fabricated semitransparent Cu electrode exhibits high transmittance in the visible range and good electrical conductivity. The authors show that the transmittance is increased by reducing the linewidth of the mesh pattern and an average transmittance of 75% is achieved. An organic light emitting diode on a flexible substrate is fabricated to demonstrate the potential use of a semitransparent Cu electrode as a transparent conducting electrode.
