Porous Liquid-Crystalline Networks with Hydrogel-Like Actuation and Reconfigurable Function

Jie Jiang et al.

Summary: A porous liquid-crystalline network (LCN) prepared using a template method exhibits peculiar actuation functions. It behaves like a hydrogel and can absorb a large volume of water, while also retaining uniaxial alignment of mesogens for a thermally induced shape change. The porous LCN can be used for versatile stimuli-triggered shape transformations, and the porosity allows for loading/removal/reloading of functional fillers.

Broadband and pixelated camouflage in inflating chiral nematic liquid crystalline elastomers

Se-Um Kim et al.

Summary: This research introduces a method using pneumatically inflating thin membranes of main-chain chiral nematic liquid crystalline elastomers to achieve pixelated structural coloration with broadband spectral shifts in a compact space. The materials can be geometrically programmed to control the size and layout of air channels for color shifting from near-infrared to ultraviolet wavelengths. Each channel can be individually controlled as a color 'pixel' for various applications such as cryptography, adaptive optics, and soft robotics.

Liquid crystal-based open surface microfluidics manipulate liquid mobility and chemical composition on demand

Yang Xu et al.

Summary: Controlling both the mobility and chemical compositions of microliter-scale aqueous droplets is crucial for next-generation open surface microfluidics. By using thermotropic liquid crystals (LCs) as the basis, this study successfully decouples cargo release functionality from droplet mobility, offering unique possibilities for novel open surface fluidic systems. Additionally, LC surfaces efficiently precipitate heavy metal ions in sliding water droplets to extremely low concentrations for over 500 cycles without pinning the droplets.

Metric mechanics with nontrivial topology: Actuating irises, cylinders, and evertors

D. Duffy et al.

Summary: Liquid crystal elastomers have great potential as actuators and artificial muscles, with the ability to contract and recover based on heating and cooling. By programing flat sheets with spatially varying director patterns, they can actuate into curved surfaces and perform as strong machines like grabbers or lifters. The study explores the actuation of programmed annular sheets, uncovering new modes of actuation like cylinders, irises, and everted surfaces, and confirming the designs through experiments and numerics. Many actuators designed can reattain their initial inner or outer radius after actuation, making them promising for avoiding potential stresses in their activated state.
