Nanostructure, Morphology, and Properties of Fluorous Copolymers Bearing Ionic Grafts
Emily M. W. Tsang,Zhaobin Zhang,Ami C. C. Yang,Zhiqing Shi,Timothy J. Peckham,Rasoul Narimani,Barbara J. Frisken,Steven Holdcroft +7 more
TL;DR: In this paper, three series of fluorous−ionic graft copolymers, partially sulfonated poly(vinylidene difluoride-co-chlorotrifluoroethylene]-g-styrene, comprising controlled graft lengths and degrees of sulfonation were synthesized.
Controlling Crystallinity in Graft Ionomers, and Its Effect on Morphology, Water Sorption, and Proton Conductivity of Graft Ionomer Membranes
TL;DR: In this article, the role of crystallinity and morphology on proton transport through solid polymer electrolytes was investigated by synthesizing graft copolymers, poly(vinylidene difluoride-co-chlorotrifluoroethylene)-g-polystyrene [P(VDF-co,CTFE]-g-PS], consisting of a hydrophobic, fluorous backbone and styrenic graft chain of varied length (DPstyrene = 39, 62, and 79).

Investigations of crystallinity and chain entanglement on sorption and conductivity of proton exchange membranes
TL;DR: In this article, the authors proposed increasing the crystallinity of hydrocarbon membranes to increase phase segregation and enhance their mechanical integrity in water by reducing their propensity to swell excessively, and to provide an ionic network when water contents are reduced when RH

Controlling Water Content and Proton Conductivity through Copolymer Morphology
Rasoul Narimani,Ami C. C. Yang,Emily M. W. Tsang,Laurent Rubatat,Steven Holdcroft,Barbara J. Frisken +5 more
TL;DR: In this paper, the authors investigated the relationship between morphology and proton conductivity in ionic copolymer membranes, and they found that the grafts with lower graft density, which are partially crystalline, develop a less-ordered morphology with a lower degree of phase separation.

Structural effects on the nano-scale morphology and conductivity of ionomer blends

TL;DR: The role of graft and diblock ionomer architecture on the morphology and properties of ionomer/fluoropolymer blends is examined in this paper, where graft ionomers are primarily insensitive to blending due to the incorporation of the non-ionic fluorous polymers into the domains of the perfluorinated backbone which does not deleteriously affect the interconnecting proton conducting ionic clusters.
