全印刷フレキシブル電子デバイスの実現に向けたナノ材料の機能性制御

软电子是指可弯曲、可拉伸和/或可与任意表面相适应的电子设备，由于其在先进制造领域的巨大应用潜力，预计将在工业革命时期带来根本性变革。然而，由于缺乏可持续的制造工艺和具有竞争力的性能，制造能够取代现有产品并在日常生活中投入使用的软电子是一个巨大的挑战。利用自主开发的双表面结构(DSA)策略，今年进一步展示了一种用于固-液界面工程的新技术。这项技术能够在环境条件下以有序和可伸缩的方式在聚合物衬底上自发形成一维(1D)功能纳米材料的图案。这种独特的液-固相互作用已被深入探索并应用于实际制作的交联银纳米线(AgNW)软电路以及具有优异的导电性和可变形性的可伸缩张力传感器。这一突破为液体介体自组装技术在软电子产品的可持续制造中开辟了新的可能性，特别是对于高度整合的皮肤集成传感器设备。

Soft electronics, referring to electronic devices that are flexible, stretchable, and/or conformable to arbitrary surfaces, are expected to bring about a radical transformation in the period of the industrial revolution owing to their unparallel potential for numerous applications in advanced manufacturing fields. However, fabricating soft electronics that can replace existing products and be put into service in our daily lives is a grand challenge due to the lack of sustainable fabrication processes and competitive performance. Using an independently developed dual-surface-architectonic (DSA) strategy, a novel technology for solid-liquid interfacial engineering has been further demonstrated this year. This technology enables the spontaneous patterning of one-dimensional (1D) functional nanomaterials on polymer substrates in an ordered and scalable manner under ambient conditions. The unique liquid-solid interaction has been thoroughly explored and applied in the practical fabrication of cross-linked silver nanowires (AgNW) soft circuits as well as stretchable tension sensors with prominent conductivity and deformability. This breakthrough opens up new possibilities for liquid-mediated self-assembly technologies in the sustainable manufacturing of soft electronics, particularly for highly conformable skin-integrated sensor devices.
