Polymer electrolyte membranes for the direct methanol fuel cell: A review
The direct methanol fuel cell (DMFC) has the potential to replace lithium-ion rechargeable batteries in portable electronic devices, but currently experiences significant power density and efficiencyExpand
Effect of Nanoscale Morphology on the Conductivity of Polymerized Ionic Liquid Block Copolymers
Polymerized ionic liquid (POIL) block copolymers represent a unique class of materials for fundamental studies of single ion conduction as a function of morphology in microphase-separated polymerExpand
Super proton conductive high-purity nafion nanofibers.
TLDR
The high proton conductivity of a single high-purity Nafion nanofiber (1.5 S/cm), which is an order of magnitude higher than the bulk Nafions, is reported, which should have a significant impact on fuel cells and sensors. Expand

TLDR
The failure of the Flory-Huggins theory and Zimm-Lundberg clustering analysis to describe water solubility and water clustering, respectively, in these glassy polymers is in part due to the equilibrium constraints under which these models are derived in contrast to the nonequilibrium state of glassypolymers.

Relative Chemical Stability of Imidazolium-Based Alkaline Anion Exchange Polymerized Ionic Liquids
We thoroughly investigate and quantify the chemical stability of an imidazolium-based alkaline anion exchange polymerized ionic liquid (PIL), poly(1-[(2-methacryloyloxy)ethyl]-3-butylimidazoliumExpand
Polymerized Ionic Liquids: The Effect of Random Copolymer Composition on Ion Conduction
Ionic conductivity in new polymerized ionic liquids is of great interest as it applies to solid-state electrolytes for electrochemical and electromechanical applications. In this study, an ionicExpand
Diffusion and sorption of methanol and water in Nafion using time-resolved Fourier transform infrared-attenuated total reflectance spectroscopy.
TLDR
The data obtained in this study reveal that the main contribution to the increase in meethanol flux is due to methanol sorption in the membrane. Expand
Triblock copolymer ionomer membranes: Part I. Methanol and proton transport
Abstract In this study, the transport properties (i.e. methanol and proton transport) of a triblock copolymer ionomer, sulfonated poly(styrene-isobutylene-styrene) (S-SIBS), at various ion contentsExpand
Nafion®/poly(vinyl alcohol) blends: Effect of composition and annealing temperature on transport properties
Abstract In this study, the transport properties (proton conductivity and methanol permeability) of Nafion ® 117, solution-cast Nafion ® , poly(vinyl alcohol) (PVA) and Nafion ® /PVA blend membranesExpand
