Abstract The effect of elastomeric damping pads, softening the collision of hard objects, is investigated comparing the reference silicone elastomer and the polydomain nematic liquid crystalline elastomer, which has a far superior internal dissipatio

Rheology studies on vitrimers have mostly focused on their linear viscoelasticity under small deformations. Here, the authors develop a full rheological understanding of vitrimer response that spans between small deformation and large-deformation reg

Nematic liquid crystal elastomers (LCE). exhibit unique mechanical properties such as large loss behaviour, which makes these materials interesting for damping applications. Here, the authors investigate the effect of anomalous damping in LCEs by com

Nematic liquid crystal elastomers (N-LCE) have a slow relaxation, which can prevent their shape recovery. Here, the authors examine mechanical hysteresis in a series of main-chain N-LCE to understand how the inherent nematic order retards and arrests

Polymer-based biomedical electronics provide a tunable platform to interact with nervous tissue both in vitro and in vivo. Ultimately, the ability to control functional properties of neural interfaces may provide important advantages to study the ner

Liquid crystal elastomers (LCEs) are stimuli-responsive materials capable of reversible and programmable shape change in response to an environmental stimulus. Despite the highly responsive nature of these materials, the modest elastic modulus and bl

Soft Matter
Fibrous liquid crystalline elastomers (LCE) are an attractive variant of LCE-based actuators due to their small thickness, leading to faster response times to stimuli, as well as the increased mechanical strength. Fabrication of LCE fibers has been a

Liquid crystalline elastomer networks cross-linked by dynamic covalent bonds (xLCE) have the ability to be (re)processed during the plastic flow. However, the current bond-exchange strategies that are used to induce plastic flow in xLCE lack the effi

This Review presents and discusses the current state of the art in "exchangeable liquid crystalline elastomers", that is, LCE materials utilizing dynamically cross-linked networks capable of reprocessing, reprogramming, and recycling. The focus here

We explore the correlation between the anomalous mechanical dissipation and the pressure-sensitive adhesion in nematic liquid crystalline elastomers (LCEs), comparing hard glassy and soft materials (high and low crosslinking density, respectively) an
