“…6), demonstrating that se-HICFs reached an equilibrium state of phase transition. This is mainly attributed to the strong hydration of high-content lithium ions in se-HICFs and the formed self-encapsulating shell that together inhibited further evaporation of water [38][39][40] , ensuring the long-term stability of the sheath-core structure (Supplementary Fig. 7) 27 .…”

Ionically conductive fibers have promising applications; however, complex processing techniques and poor stability limit their practicality. To overcome these challenges, we proposed a stress-induced adaptive phase transition strategy to conveniently fabricate self-encapsulated hydrogel-based ionically conductive fibers (se-HICFs). se-HICFs can be produced simply by directly stretching ionic hydrogels with ultra-stretchable networks (us-IHs) or by dip-drawing from molten us-IHs. During this process, stress facilitated the directional migration and evaporation of water molecules in us-IHs, causing a phase transition in the surface layer of ionic fibers to achieve self-encapsulation. The resulting sheath-core structure of se-HICFs enhanced mechanical strength and stability while endowing se-HICFs with powerful non-contact electrostatic induction capabilities. Mimicking nature, se-HICFs were woven into spider web structures and camouflaged in wild environments to achieve high spatiotemporal resolution 3D depth-of-field sensing for different moving media. This work opens up a convenient route to fabricate stable functionalized ionic fibers.

One of the methods to fabricate ordered micro-structured film is the usage of water droplets from humid-air flow as template. However, humid-air flow on the surface of polymer solution during cast of porous polymeric film may lead to uneven surface of the porous polymeric film. Moreover, the influence of atmosphere humidity on the average pore size of porous polymeric film is significant. In this study, we developed a novel method to fabricate even surface of porous polymeric film and reduce the influence of atmosphere humidity on the pore size. To achieve this purpose, an ultrasonic fogging device was employed to produce water droplets instead of humid air. The water droplets produced by an ultrasonic fogging device may contain negative ions to prevent the water droplets from aggregation. Therefore, the pore size of water droplets is able to be stabilized. In addition, the water droplets produced by an ultrasonic fogging device are able to fully fill in container in advance, which may avoid large humid-air flow to agitate the surface of polymer solution. Thus the even surface of porous polymeric film can be acquired.
