A long-chain protic ionic liquid inside silica nanopores: enhanced proton mobility due to efficient self-assembly and decoupled proton transport

Garaga, Mounesha N.; Dracopoulos, Vassilios; Werner-Zwanziger, Ulrike; Zwanziger, Josef W.; Maréchal, Manuel; Persson, Michael; Nordstierna, Lars; Martinelli, Anna

We report enhanced protonic and ionic dynamics in an imidazole/protic ionic liquid mixture confined within the nanopores of silica particles. The ionic liquid is 1-octylimidazolium bis(trifluoromethanesulfonyl)imide (), while the silica particles are microsized and characterized by internal well connected nanopores. We demonstrate that the addition of imidazole is crucial to…

Ion Transport and Interfacial Dynamics in Disordered Block Copolymers of Ammonium-Based Polymerized Ionic Liquids

Harris, Matthew A.; Heres, Maximilian F.; Coote, Jonathan; Wenda, André; Strehmel, Veronika; Stein, Gila E.; Sangoro, Joshua

A series of diblock copolymers bearing a polymerized ionic liquid (polyIL) block (poly(N-(methacryloyloxy)ethyl-N,N-dimethyl-N-ethylammonium bis(trifluoromethylsulfonyl)imide)) and a noncharged block (poly(methyl methacrylate) (PMMA)) or poly(n-butyl methacrylate) (PBuMA)) were studied using differential scanning calorimetry (DSC), small-angle X-ray scattering (SAXS), wide-angle X-ray scattering…

Long Walks in Hierarchical Porous Materials due to Combined Surface and Configurational Diffusion

Vattipalli, Vivek; Qi, Xiaoduo; Dauenhauer, Paul J.; Fan, Wei

Hierarchical materials with porous structures at different length scales (i.e., micropore and mesopore) are an emerging class of materials. However, the lack of fundamental understanding of mass transport properties significantly limits rational development of these materials for applications in catalysis and separation. In this study, we evaluated the mass transport…

In Operando Small-Angle X-ray Scattering Investigation of Nanostructured Polymer Electrolyte for Lithium-Ion Batteries

Möhl, Gilles E.; Metwalli, Ezzeldin; Müller-Buschbaum, Peter

Electrochemical energy storage still presents one of the biggest challenges that society has to face by developing alternative lithium-ion batteries (LIBs) as they already satisfy important preconditions by providing the highest energy and power densities of all battery systems. Nowadays, the employed liquid electrolytes in LIBs do not merge the…

Correlating molecular and crystallization dynamics to macroscopic fusion and thermodynamic stability in fused deposition modeling; a model study on polylactides

Srinivas, Varun; van Hooy-Corstjens, Catharina S. J.; Harings, Jules A. W.

To define molecular parameters for fused deposition modeling of mechanically integral polylactide parts, the effect of intrinsic local heat fluctuations on morphology and structure evolution is studied. Macroscopic fusion during melt deposition is governed by molecular dynamics of solidification and positively affected by low print speed, low molar mass. However,…

Proton conductive cationic nanoporous polymers based on smectic liquid crystal hydrogen-bonded heterodimers

Mulder, Dirk-Jan; Liang, Ting; Xu, Yifei; Schiphorst, Jeroen ter; Scheres, Luc M. W.; Oosterlaken, Bernette M.; Borneman, Zandrie; Nijmeijer, Kitty; Schenning, Albertus P. H. J.

The fabrication of a cationic nanoporous smectic liquid crystal network (LCN) based on hydrogen bonded heterodimers is presented. The method relies on a supramolecular complex made from a pyridyl bearing reactive mesogen hydrogen bonded to a non-reactive benzoic acid template. Upon addition of a cross-linker, a smectic liquid crystalline phase…

Molecular Structure, Chain Dimensions, and Linear Rheology of Poly(4-vinylbiphenyl)

López-Barrón, Carlos R.; Zhou, Huaxing; Younker, Jarod M.; Mann, Jason A.

The linear viscoelasticity and molecular structure of a series of poly(4-vinylbiphenyl) (PVBP) samples with polydispersities ranging from 1.08 to 2.75 are investigated using wide-angle X-ray scattering (WAXS), small-angle neutron scattering (SANS), and rheological measurements. PVBP chain dimensions, such as statistical segment length, persistence length, and packing length, are obtained from…

The Different Roles of Entropy and Solubility in High Entropy Alloy Stability

Ruiz-Yi, Benjamin; Bunn, Jonathan Kenneth; Stasak, Drew; Mehta, Apurva; Besser, Matthew; Kramer, Matthew J.; Takeuchi, Ichiro; Hattrick-Simpers, Jason

Multiprincipal element high entropy alloys stabilized as a single alloy phase represent a new material system with promising properties, such as high corrosion and creep resistance, sluggish diffusion, and high temperature tensile strength. However, the mechanism of stabilization to form single phase alloys is controversial. Early studies hypothesized that a…
