62 Programmable actuation of porous poly(ionic liquid) membranes by aligned carbon nanotubes
关键字:actuators poly(ionic liquids) porous membranes programmable bending 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.

Synthesis of poly(arylene benzimidazole) sulfone (PABIS) and preparation of hollow PABIS microspheres
关键字:poly(arylene benzimidazole) sulfone; N–C coupling reaction; micro-liquid technique; hollow microsphere
4,4’-Di(benzimidazolyl)benzene sulfone, as the monomer, is very readily available by the reaction of 4,4’-dicarboxydiphenyl sulfone with o-phenylenediamine, and poly(arylene benzimidazole) sulfone (PABIS) has been synthesized by the condensation polymerization of bis(4-fluorophenyl) sulfone with di(benzimidazolyl)benzene sulfone via an N–C coupling reaction. The structure of the polymer was c...

Side-On Main-Chain Liquid Crystalline Polymers Prepared by Acyclic Diene Metathesis Polymerization and Thiol-Ene Click Step-Growth Polymerization
关键字:LCP
In this manuscript, we design and synthesize a
series of X-shaped mesogenic monomers, bearing two terminal-alkene tails.
Starting from these X-shaped monomers, acyclic
diene metathesis polymerization and thiol-ene polyaddition are applied for the first time to prepare two series
of side-on main-chain liquid crystalline polymers respectively.
