3. Shear Induced Molecular Alignments of A Side-Chain Liquid Crystalline Polyacetylene Containing Biphenyl Mesogens
Mesomorphic properties of a side chain liquid crystalline polyacetylene, poly(11-{[(40-heptyloxy-4-biphenylyl)carbonyl]oxy}-1-undecyne) (PA9EO7), are investigated using polarized optical microscope, X-ray diffraction, and transmission electron microscope. Polymer PA9EO7 forms enantiotropic smectic A and smectic B phases. It also exhibits an additional high order smectic phase, a sandwich structu...

【71 Macromolecular Rapid Communications 】 Poly(ionic liquid)-derived N-doped carbons with hierarchical porosity for lithium and sodium ion batteries
The performance of lithium‐ and sodium‐ion batteries relies notably on the accessibility to carbon electrodes of controllable porous structure and chemical composition. This work reports a facile synthesis of well‐defined N‐doped porous carbons (NPCs) using a poly(ionic liquid) (PIL) as precursor, and graphene oxide (GO)‐stabilized poly(methyl methacrylate) (PMMA) nanoparticles as sacrificial...

【63 Advanced Materials Interfaces】 Programmable actuation of porous poly(ionic liquid) membranes by aligned carbon nanotubes
A porous composite membrane, combined poly(ionic liquids) with aligned carbon nanotubes that shows anisotropic actuation toward organic solvent is developed. The membrane actuator shows rapid and reversible actuation in response to acetone vapor as well as improved conductivity. These properties allow the composite membrane to be organic solvent‐induced actuator as well as a power switch.

[Nature Chemistry] Photoswitching of Glass Transition Temperatures of Azobenzene-containing Polymers Induces Reversible Solid-to-liquid Ttransitions
The development of polymers with switchable glass transition temperatures (Tg) can address scientific challenges such as the healing of cracks in high-Tg polymers and the processing of hard polymers at room temperature without using plasticizing solvents. Here, we demonstrate that light can switch the Tg of azobenzene-containing polymers (azopolymers) and induce reversible solid-to-liquid transi...

(Macromolecules) Aggregation-Induced Emission Luminogen-Functionalized Liquid Crystal Elastomer Soft Actuators
An aggregation-induced emission (AIE)-active liquid crystal elastomer (LCE) soft actuator is fabricated through chemical incorporation of a four-alkenylarmed tetraphenylethene-core cross-linker into a main-chain LCE matrice by a facile in situ two-step acyclic diene metathesis (ADMET) polymerization/cross-linking method. The LCE sample is endowed with the ability to readily tune the photolumines...

(J. Mater. Chem. C) A Cut-and-Paste Strategy towards Liquid Crystal Elastomers with Complex Shape Morphing
Nowadays, with the rapid progress in soft robotics and aerospace technology, novel soft actuator materials with reversible and complex shape morphing capabilities, such as helical curling, buckling, accordion-like folding, self-oscillating, waving and other three-dimensional motion modes, are highly desirable. In this manuscript, we report a new cut-and-paste method to construct liquid crystal e...

Molecular-weight dependence of phase structure and viscosity in a liquid crystalline polyester with strong π–π interaction
In this article, the molecular-weight dependence of the phase structure, rheological behaviour and thermal stability of a main-chain liquid crystalline polyester (PBDPS) with strong π–π interaction was investigated in details by differential scanning calorimetry, polarising optical microscopy, wide-angle X-ray diffraction, dynamic oscillatory rheological measurements and thermogravimetric ana...
