Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

A supramolecular non-mesogenic route towards autonomous liquid crystal elastomer soft robots

Nature Communications
Liquid crystal elastomers are unique choices for designing the next generation soft robots. Their synthesis relies exclusively on the polymerization/crosslinking of reactive mesogens with high molecular rigidity, necessitating high energy input to ...

Localized soft elasticity in liquid crystal elastomers

Nature Communications, 2016
Ruggedized stretchable electronic devices motivate the development of globally stretchable yet locally stiff materials. Here, Ware et al. programme the self-organization of liquid crystal elastomers to yield stretchable materials of homogenous ...

Highly Entangled Bottlebrush Polymer Networks

Advanced Materials, EarlyView.
Bottlebrush polymers are difficult to entangle, enabling ultrasoft yet brittle networks. We report highly entangled bottlebrush elastomers that remain ultrasoft (∼1 kPa) yet stretch to ∼1800% and exhibit exceptional fatigue resistance. Their intrinsic fatigue strength—fatigue threshold normalized by modulus—surpasses that of highly entangled linear ...

A Light-Powered Liquid Crystal Elastomer Roller

Polymers, 2023
Achieving and controlling the desired movements of active machines is generally accomplished through precise control of artificial muscles in a distributed and serialized manner, which is a significant challenge. The emerging motion control strategy based on self-oscillation in active machines has unique advantages, including directly harvesting energy

Dynamic Theory of Polydomain Liquid Crystal Elastomers

Physical Review Letters, 2015
When liquid-crystal elastomers are prepared without any alignment, disordered polydomain structures emerge as the materials are cooled into the nematic phase. These polydomain structures have been attributed to quenched disorder in the cross-linked polymer network.

Ambient Light‐Activatable Luminescent Particle‐Embedded Conformal Patch for Photochemical Tissue Bonding and Photobiomodulated Healing

Advanced Materials, EarlyView.
We report a wearable photonic patch integrating room light‐ and sunlight‐activatable luminescent particles (RSLPs) for both photochemical tissue bonding and photobiomodulation. RSLPs harvest ambient light and emit red luminescence to drive chlorin e6–mediated collagen crosslinking.
