Abstract In nature, many living organisms exhibiting unique structural coloration and soft-bodied actuation have inspired scientists to develop advanced colored soft actuators toward biomimetic robots. However, it is challenging simultaneously biomimic the angle-independent color shape-morphing capabilities found in plum-throated cotinga flying bird. Herein, we report MXene-based with that are fabricated through controlled self-assembly of colloidal SiO 2 nanoparticles onto highly aligned MXene films followed by vacuum-assisted infiltration polyvinylidene fluoride into interstices. The resulting exhibit brilliant, color, as well ultrafast recovery speeds (a maximum curvature 0.52 mm −1 can be achieved within 1.16 s, a time ~ 0.24 s) response acetone vapor. As proof-of-concept illustrations, applied demonstrate blue gripper-like bird’s claw capture target, artificial green tendrils twine around tree branches, an multicolored butterfly flutter its wings upon cyclic exposure strategy expected offer new insights development multifunctional for somatosensory robotics next-generation intelligent machines.

With ultralight weight, low thermal conductivity, and extraordinary high-temperature resistance, carbon aerogels hold tremendous potential against severe threats encountered by hypersonic vehicles during the in-orbit operation re-entry process. However, current 3D are plagued irreconcilable contradictions between adiabatic mechanical performance due to monotonicity of building blocks or uncontrollable assembly behavior. Herein, a spatially confined strategy multiscale low-dimensional nanocarbons is reported decouple stress heat transfer. The nanofiber framework, basis for transferring loading strain, covered continuous thin-film-like layer formed aggregation nanoparticles, which in combination serve as fundamental structural units generating an elastic behavior while yielding compartments suppress gaseous fluid diffusion within distinct partitions. resulting all-carbon with hierarchical cellular structure quasi-closed cell walls achieve best thermomechanical insulation trade-off, exhibiting flyweight density (24 mg cm

In order to form and regulate skin color throughout the entire visible range, chameleons use a non-close-packed arranged guanine nanocrystals in iris cells. Inspired by chameleons, PS@SiO2 particles are embedded poly(ethylene glycol) phenyl ether acrylate (PEGPEA) prepare photonic crystal thin films. Photonic films have bright structural (reflectivity >60%), high tensile strain (ε = 70%), sensitivity (2.16 nm/%–1), fast response time (1.9 nm/ms), wide tuning range of reflection wavelength (Δλ 152 nm). The unique core–shell structure microspheres has elasticity stretchability. Polystyrene (PS) improves refractive index difference between nanometer elastomer matrix, making film brighter. Nondense arrays can ignore particle rearrangement under strain, mechanical discoloration process completely reversible. Based on these characteristics, this is used as wearable sensor for human body, which report various actions outputting different colors during change process. Meanwhile, simple manufacturing processes potential achieve large-scale production. So certain practical value visual sensing, display, anticounterfeiting.

Structural coloration generates colors by the interaction between incident light and micro- or nano-scale structures. It has received tremendous interest for decades, due to advantages including robustness against bleaching environmentally friendly properties (compared with conventional pigments dyes). As a versatile strategy, tuning of structural based on nanoscale photonic structures been extensively explored can enable broad range applications displays, anti-counterfeiting, coating. However, scholarly research had limited impact commercial products because their disadvantages in cost, scalability, fabrication. In this review, we analyze key challenges opportunities development colors. We first summarize fundamental mechanisms design strategies while reviewing recent progress realizing dynamic coloration. The promising potential optical information processing displays are also discussed elucidating most prominent that prevent them from translating into technologies market. Finally, address new underexplored community but be achieved through multidisciplinary within emerging areas.
