Transfer printing is one of the key nanofabrication techniques for the large‐scale manufacturing of complex device architectures. It provides a cost‐effective and high‐throughput route for the integration of independently processed materials into spatially tailored architectures. Furthermore, this method enables the fabrication of flexible and curvilinear devices, paving the way for the fabrication of a new generation of technologies for optics, electronics, and biomedicine. In this work, hydroxypropyl cellulose (HPC) membranes are used as water soluble adhesives for transfer printing processes with improved performance and versatility compared to conventional silicone alternatives. The high‐water solubility and excellent mechanical properties of HPC facilitate transfer printing with high yield for both metal and carbon nanotubes (CNTs) inks. In the case of metal inks, crack‐free stripping of silver films and the simple fabrication of Moiré Plasmonic architectures of different geometries are demonstrated. Furthermore, HPC membranes are used to transfer print carbon nanotube films with different thicknesses and up to 77% transparency in the visible and near infrared region with potential applications as transparent conductive substrates. Finally, the use of prepatterned HPC membranes enables nanoscale patterning of CNT with feature resolution down to 1 µm.

用于碳纳米管和金属纳米结构转移印刷的羟丙基纤维素胶

转移印刷是大规模制造复杂设备体系结构的关键纳米加工技术之一。它为将独立处理的材料集成到空间定制的架构中提供了一种经济高效的高吞吐量途径。此外，该方法能够制造柔性和曲线形的设备，为制造用于光学，电子和生物医学的新一代技术铺平了道路。在这项工作中，与传统的有机硅替代品相比，羟丙基纤维素（HPC）膜被用作用于转移印刷工艺的水溶性粘合剂，具有改进的性能和多功能性。HPC的高水溶性和出色的机械性能有利于金属和碳纳米管（CNT）油墨的转移印刷，且产率很高。在金属油墨的情况下，展示了银膜的无裂纹剥离和不同几何形状的摩尔纹等离子架构的简单制造。此外，HPC膜用于在可见光和近红外区域转移具有不同厚度和高达77％透明性的印刷碳纳米管膜，并有可能用作透明导电基材。最后，使用预图案化的HPC膜可实现CNT的纳米级图案化，特征分辨率低至1 HPC膜用于在可见光和近红外区域转移具有不同厚度和高达77％透明性的印刷碳纳米管膜，并有可能作为透明导电基材使用。最后，使用预图案化的HPC膜可实现CNT的纳米级图案化，特征分辨率低至1 HPC膜用于在可见光和近红外区域转移具有不同厚度和高达77％透明性的印刷碳纳米管薄膜，并有可能用作透明导电基材。最后，使用预图案化的HPC膜可实现CNT的纳米级图案化，特征分辨率低至1 μ微米。
