Poly(N,N-diallylazacycloalkane)s for Anion-Exchange Membranes Functionalized with N-Spirocyclic Quaternary Ammonium Cations

Olsson, Joel S.; Pham, Thanh Huong; Jannasch, Patric

The alkaline stability of organic cations tethered to anion-exchange membranes (AEMs) is essential for the long-term performance of alkaline membrane fuel cells and electrolyzers. Here, we have prepared and studied the thermal and alkaline stability of a series of polyelectrolytes functionalized with N-spirocyclic quaternary ammonium (QA) cations. N,N-Diallylazacycloalkane quaternary salts…

Morphological Behavior of A2B Block Copolymers in Thin Films

Kim, Hyeyoung; Kang, Beom-Goo; Choi, Jaewon; Sun, Zhiwei; Yu, Duk Man; Mays, Jimmy; Russell, Thomas P.

Copolymer composed of two poly(2-vinylpyridine) blocks and one polystyrene block ((P2VP)2–PS) with a PS volume fraction (ΦPS) of 0.44 was synthesized, and their morphologies in bulk and thin films were compared to linear block copolymers (BCPs) having a similar ΦPS (PS-b-P2VP). For the symmetric diblock copolymer, a lamellar morphology was…

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…

Microemulsions as Potential Carriers of Nisin: Effect of Composition on Structure and Efficacy

Chatzidaki, Maria D.; Papadimitriou, Konstantinos; Alexandraki, Voula; Tsirvouli, Eirini; Chakim, Zena; Ghazal, Aghiad; Mortensen, Kell; Yaghmur, Anan; Salentinig, Stefan; Papadimitriou, Vassiliki; Tsakalidou, Effie; Xenakis, Aristotelis

Water-in-oil (W/O) microemulsions based on either refined olive oil (ROO) or sunflower oil (SO), distilled monoglycerides (DMG), and ethanol were used as nisin carriers in order to ensure its effectiveness as a biopreservative. This work presents experimental evidence on the effects of ethanol concentration, hydration, the nature of oil, and…

Well-defined metal-polymer nanocomposites: The interplay of structure, thermoplasmonics, and elastic mechanical properties

Reig, David Saleta; Hummel, Patrick; Wang, Zuyuan; Rosenfeldt, Sabine; Graczykowski, Bartlomiej; Retsch, Markus; Fytas, George

Metal-polymer nanocomposites are hybrid materials combining the superior plasmonic, electrical, and thermal properties of metals with the good elasticity and manufacturability of polymers. This renders metal-polymer nanocomposites promising candidates for conductive filler and coating applications, where mechanical properties are optothermally coupled. Here, we study the interplay of…

Morphology, thermal properties and molecular dynamics of syndiotactic polystyrene (s-PS) nanocomposites with aligned graphene oxide and graphene nanosheets

Koutsoumpis, Stefanos; Klonos, Panagiotis; Raftopoulos, Konstantinos N.; Papadakis, Christine M.; Bikiaris, Dimitrios; Pissis, Polycarpos

In this work we report morphological, calorimetric and dielectric results for polymer nanocomposites (PNCs) based on syndiotactic polystyrene (s-PS) filled with graphene oxide (GO) and graphene by employing melt-mixing. The preparation of the PNCs resulted in aligning of the filler in the polymer matrix as observed by SEM and Wide…

Thermally cross-linked diaminophenylindane (DAPI) containing polyimides for membrane based gas separations

Dose, Michelle E.; Chwatko, Malgorzata; Hubacek, Ivo; Lynd, Nathaniel A.; Paul, Donald R.; Freeman, Benny D.

This study aims to expand structure-property relationships of diaminophenylindane (DAPI)-containing polyimides and the influence of thermal cross-linking on gas transport properties of such materials. A polyimide synthesized from hexafluoroisopropylidene diphthalic anhydride (6FDA), DAPI, and diaminobenzoic acid (DABA) in a molar ratio of 0.5/0.33/0.17, 6FDA0.5-DAPI0.33/DABA0.17, was crosslinked…

3D Printing of Liquid Crystal Elastomeric Actuators with Spatially Programed Nematic Order

Kotikian, Arda; Truby, Ryan L.; Boley, John William; White, Timothy J.; Lewis, Jennifer A.

Liquid crystal elastomers (LCEs) are soft materials capable of large, reversible shape changes, which may find potential application as artificial muscles, soft robots, and dynamic functional architectures. Here, the design and additive manufacturing of LCE actuators (LCEAs) with spatially programed nematic order that exhibit large, reversible, and repeatable contraction with…
