- Influence of the crystallization on the molecular mobility and ionic DC conductivity behaviors of relaxor ferroelectric P(VDF-TrFE-CTFE) terpolymers
Qing Liu, Xunqian Yin, Claude Richard and Jean-Fabien Capsal

The molecular mobility associated with segmental dynamics ( relaxation) and local motion ( relaxation) of semicrystalline polymers strongly depends upon crystallinity and morphology. In this work, relaxation and relaxation processes in the amorphous phase as a function of the evolution of crystallization were investigated by broadband dielectric spectroscopy. Due to the enhancement of the interphase region, the terpolymer with a higher crystallinity fraction exhibited fragile behavior. The ferroelectric-paraelectric Curie transition and charge carrier motions were also addressed.
- From toroidal to rod-like nanostructure, a mechanism study for the reversible morphological control on amphiphilic triblock copolymer micelles

The mechanism of the reversible transition between rod-like and toroidal nanostructures of P4VP-b-PS-b-P4VP triblock copolymer has been investigated. The toroidal micelles, evolving from fibers at 20 °C, can transform into rod-like micelles as the temperature either gradually or directly increases to 80 °C, and vice versa. Morphologies of micelles are dependent on the temperature, whereas the reversible transition mechanism is related to the route of the temperature change.
- How preparation and modification parameters affect PB-PEO polymersome properties in aqueous solution
Joachim Habel, Anayo Ogbonna, Nanna Larsen, Simon Krabbe, Kristoffer Almdal and Claus Hélix-Nielsen

Two polymersome formation methods, solvent-evaporation (SE) and detergent-mediated film rehydration (DFR), are compared. DFR prepared polymersomes showed a three times higher permeability revealed by stopped-flow light scattering, where SE prepared polymersomes broke down faster to smaller structures (< 50 nm diameter) when processed with extrusion. Additionally, dialysis and biobeads for detergent removal were compared to investigate the influence of these methods on bilayer conformation and polymer rearrangement when detergent is removed from the bilayer.
- Molecularly imprinted polymers bearing spiropyran-based photoresponsive binding sites capable of photo-triggered switching for molecular recognition activity
Nobuo Murase, Takashi Mukawa, Hirobumi Sunayama and Toshifumi Takeuchi
Article first published online: 21 APR 2016 | DOI: 10.1002/polb.24066
Photoresponsive molecularly imprinted nanocavities for atrazine were prepared using a new functional monomer bearing a photoresponsive spiropyran moiety with a carboxy group that can interact with atrazine. Photo-triggered switching of the binding activity was found to decrease dramatically after UV light irradiation, suggesting that the spiropyran moiety incorporated into the binding cavities was transformed to the merocyanine form, resulting in unfavorable translocation of the carboxy group for the atrazine binding.
- Rouse–Bueche theory and the calculation of the monomeric friction coefficient in a filled system
Luca Martinetti, Christopher W. Macosko and Frank S. Bates
Article first published online: 20 APR 2016 | DOI: 10.1002/polb.24045
The motion of a polymer chain depends on the local friction (ζ0) experienced by its fundamental subunits (Gaussian submolecules). Knowledge of ζ0 is therefore a prerequisite to understand the viscoelastic response of the material in terms of its internal structure. In this article, a simple method is introduced to estimate ζ0 and the size of Gaussian submolecules in filled systems, such as filled rubbers or block copolymer thermoplastic elastomers at temperatures relevant for end-use applications.
