Reversible Self-Actuated Thermo-Responsive Pore Membrane. [PDF]

, 2016
Smart membranes, which can selectively control the transfer of light, air, humidity and temperature, are important to achieve indoor climate regulation. Even though reversible self-actuation of smart membranes is desirable in large-scale, reversible self-

Periodic Polymerization and the Generation of Polymer Giant Vesicles Autonomously Driven by pH Oscillatory Chemistry

Frontiers in Chemistry, 2021
Using the radicals generated during pH oscillations, a semibatch pH oscillator is used as the chemical fuel and engine to drive polymerization induced self-assembly (PISA) for the one-pot autonomous synthesis of functional giant vesicles.

Polymerization‐induced self‐assembly of metallo‐polyelectrolyte block copolymers [PDF]

Journal of Polymer Science, 2019
ABSTRACTCobaltocenium‐containing polyelectrolyte block copolymer nanoparticles were prepared via polymerization‐induced self‐assembly (PISA) using aqueous dispersion RAFT polymerization. The cationic steric stabilizer was a macromolecular chain‐transfer agent (macro‐CTA) based on poly(2‐cobaltocenium amidoethyl methacrylate chloride) (PCoAEMACl), and ...

Enzyme-assisted Photoinitiated Polymerization-induced Self-assembly in Continuous Flow Reactors with Oxygen Tolerance

Chinese Journal of Polymer Science, 2021
Polymerization-induced self-assembly (PISA) is an emerging method for the preparation of block copolymer nano-objects at high concentrations. However, most PISA formulations have oxygen inhibition problems and inert atmospheres (e.g. argon, nitrogen) are

Self-Assembly of Supramolecular Triblock Copolymer Complexes [PDF]

, 2010
Four different poly(tert-butoxystyrene)-b-polystyrene-b-poly(4-vinylpyridine) (PtBOS-b-PS-b-P4VP) linear triblock copolymers, with the P4VP weight fraction varying from 0.08 to 0.39, were synthesized via sequential anionic polymerization.
