With the development of photonics, there has been a push towards optoelectronic devices that are flexible, rollable, wearable, user-friendly, and robust to improve human-machine interfaces. To be integrated onto human body, these devices must be biocompatible and be able to withstand mechanical deformation and different bending curvatures. Figure 1 shows the rollable and soft photonic meta-device.

Rapid fabrication of network-structured amphiphilic block copolymer photonic crystal films could be accomplished by the facile spin-casting process. By immersing into alcohols, the swollen network could give rise to the visible structural coloration. Unlike the disappearance of the visible reflection in the lamellar film, the network structure could trap the visible structural coloration by vitrification of the network after drying, namely, trapping of structural coloration (TOSC). With further control of diffusive distance and diffusivity, full-visible-wavelength structural colorations are obtained. This TOSC is reversible and responsive with heat. By TOSC, we firstly fabricate the flexible copolymer photonic crystal featuring tunable and reversible structural colorations in solid state.

Our team has developed a layer-by-layer hydrophilic membrane (LHM) as the “bendable water-enabled portable power banks”. It is bendable, cost-effective, lightweight, environmental-friendly,high-efficient. Moreover, it could achieve high-voltage (~0.8 V), high-current (~80 μA)long-lasting (4 hr) power output by dropping a few drops of DI water (or electrolyte solutions), which can be described as a "black technology" towards green clean energy.
