Metal oxides have broad multifunctionality and important applications to energy, sensing, and information display. Printed electronics have recently adopted metal oxides to push the limits of performance and stability for flexible thin film systems. However, a grand challenge in this field is to achieve these properties while balancing the thermal budget, which critically determines the applicability, flexibility, and cost of these systems. This paper presents a focused review of printed metal oxide electronics, highlighting our recent work developing high-performance, printed transistors processed at low temperatures via aqueous precursor chemistries, nanomaterial hybrid inks, and ultraviolet annealing. These results reveal the potential for printing uniquely high-performance active devices (electronic mobility >10 cm V s) but also illustrates the utility of nanocomposites that integrate nanomaterials within a metal oxide matrix for improving device performance.
金属氧化物具有广泛的多功能性和在能源、传感和信息显示方面的重要应用。印刷电子学最近采用金属氧化物来推动柔性薄膜系统的性能和稳定性极限。然而，该领域的一个重大挑战是在平衡热预算的同时实现这些特性，这对这些系统的适用性、灵活性和成本具有关键影响。本文对印刷金属氧化物电子学进行了重点综述，重点介绍了我们最近通过水相前体化学、纳米材料混合油墨和紫外线退火在低温下处理高性能印刷晶体管的工作。这些结果表明了打印独特的高性能有源器件（电子迁移率>10cmV s）的潜力，但也说明了纳米复合材料的实用性，它将纳米材料集成到金属氧化物基质中以提高器件性能。
