Three-dimensional tubular origami, fabricated by the self-rolling of functional nanomembranes, is of great interest due to its numerous opportunities for applications in photochemical sensing, intelligent actuators, microrobots, electronics, and many others. A continuing opportunity of this area is in the development of strategies for fabricating tubular origami, in solvent-free and low-cost conditions. This paper proposed a semidry release approach, allowing for the sacrificial layer-free, vapor-assisted self-rolling, and recyclable use of substrates, to create microscale tubular origami. Interface engineering designs that involve hydrophilic and hydrophobic material stacks are introduced to realize the semidry release of nanomembranes, which finally self-roll into multifunctional tubular structures. Systematic experimental and theoretical studies demonstrate the controllability of their dimensions. Finally, a bioresorbable microtube with potential for transient implantable devices is demonstrated. Our present work adds to the portfolio of routes for the construction of tubular origami, which can be utilized as functional platforms for fundamental studies and practical applications.

用于管状折纸的纳米膜的半干释放

由功能性纳米膜的自卷制成的三维管状折纸因其在光化学传感、智能执行器、微型机器人、电子产品和许多其他领域的众多应用机会而备受关注。该领域的一个持续机会是在无溶剂和低成本条件下制定制造管状折纸的策略。本文提出了一种半干释放方法，允许无牺牲层、蒸汽辅助自卷和基材的可回收使用，以创建微型管状折纸。引入涉及亲水和疏水材料堆叠的界面工程设计，以实现纳米膜的半干释放，最终自卷成多功能管状结构。系统的实验和理论研究证明了它们尺寸的可控性。最后，展示了具有瞬时植入装置潜力的生物可吸收微管。我们目前的工作增加了用于构建管状折纸的路线组合，可用作基础研究和实际应用的功能平台。
