Multi‐Mode Mechanochromic Responses from Cholesteric Liquid Crystal Elastomer Tubes of Uniform Sheath

open access: yesAdvanced Materials, EarlyView.
The structural‐colored tube is created from cholesteric liquid crystal elastomers, exhibiting uniform color changes with high strain sensitivity upon extension and inflation. The color change occurs across multiple mechanochromic modes, highlighting the influence of molecular anisotropy and tubular geometry on strain sensitivity.

Halogen‐Bonded Liquid Crystal Elastomers as Initiator‐Free Photochemical Actuators

open access: yesAdvanced Materials, EarlyView.
The combination of dynamic disulfide bonds and halogen bonds in chain‐extended liquid crystal elastomers enables the fabrication of photochemical actuators without the need for a photoinitiator, advancing the design of multimodal soft actuators that can be reprogrammed and reprocessed through supramolecular functionalization.

Robust Mix‐Charged Polyzwitterionic Hydrogels for Ultra‐Efficient Atmospheric Water Harvesting and Evaporative Cooling

open access: yesAdvanced Materials, EarlyView.
Conventional atmospheric water‐harvesting hydrogels prioritize hygroscopicity at the expense of mechanics, hindering its practical applications. The proposed hygroscopic mix‐charged polyzwitterionic hydrogel(THMPH) achieves a trade‐off between high water absorption and exceptional mechanical robustness through a strength gradient‐enhanced ionic cross ...
