基于可再生纳米材料的柔性电子产品的高产量制造是一个极端的挑战。在这里，我们展示了纳米材料网络（膜）在疏水性聚合物基底（即，聚二甲基硅氧烷）中的疏水纳米颗粒的超声分散体。自限声浸涂（SDC）组件的特征在于超快的撤回速度（16米/分钟，一至五个数量级大于现有的纳米材料浸涂工艺）和不敏感的基板几何形状。它适用于广泛的疏水纳米材料，从石墨烯到碳纳米管和聚（甲基丙烯酸甲酯）纳米颗粒。sono修复方法仅需要在水中超声处理1分钟即可再生石墨烯/聚二甲基硅氧烷应变传感器。此外，SDC可以与其他纳米材料沉积方法（例如，电镀）以构建异质结构和集成器件。
High throughput manufacturing of regenerable nanomaterial-based flexible electronics represents an extreme challenge. Here we demonstrate a rapid and eco-friendly assembly and regeneration of nanomaterial networks (films) on a hydrophobic polymer substrate (i.e., polydimethylsiloxane) from a sonicated dispersion of hydrophobic nanoparticles in water. The self-limiting sono dip coating (SDC) assembly is characterized by an ultrafast withdrawal speed (16 m/min, one to five orders of magnitude greater than that of existing nanomaterial dip-coating processes) and insensitivity to substrate geometry. It is applicable to a wide range of hydrophobic nanomaterials, from graphene to carbon nanotubes and poly (methyl methacrylate) nanoparticles. The sono healing method requires only 1 min sonication in water to regenerate graphene/polydimethylsiloxane strain sensors. Furthermore, the SDC can be combined with other nanomaterial deposition methods (e.g., electroplating) to build heterostructures and integrated devices.
