Intrinsic carbon nanotube liquid crystalline elastomer photoactuators for high-definition biomechanics

Juzhong Zhang et al.

Summary: This study proposes a simple strategy to prepare a photoresponsive elastomer by grafting carbon nanotubes onto a thermally-sensitive liquid-crystalline elastomer network, enhancing its mechanical and photothermal properties. The elastomer with ultralow loading of carbon nanotubes exhibits stable response and increased tensile strength. This design strategy can be used to manufacture high-precision, remote-control smart devices.

Actuation Mechanisms of a Semicrystalline Elastomer-Based Polymer Artificial Muscle with High Actuation Strain

Jin Wang et al.

Summary: This study reports a sePAMs with high actuation strain and provides an in-depth analysis of its mechanisms. Both entropy-elastic actuation and crystallization-induced elongation/melting-induced contraction play important roles in controlling the actuation behavior. The oriented crystallization causes an increase in entropy of the amorphous section, resulting in further elongation of the network.

Triple and Two-Way Reversible Shape Memory Polymer Networks with Body Temperature and Water Responsiveness

Ruixue Liang et al.

Summary: Through thiol-ene chemistry, shape memory polymers (SMPs) based on hydrophobic polytetrahydrofuran (PTHF) and hydrophilic poly(ethylene glycol) (PEG) oligomers were successfully fabricated, showing a body temperature-triggered two-way shape memory effect and a body temperature- and water-triggered one-way triple shape memory effect. These features make the polymers promising for biomedical applications, as demonstrated by their application as a new type of esophageal stent with adjustable and self-expandable properties, as well as the ability to release drugs.
