Effect of Nanodiamond (ND) Surface Functionalization on the Properties of ND/PEEK Composites

Wahab, Z.; Marsh, Z. M.; Tessema, A.; Kidane, A.; Stefik, M.; Anneaux, B. L.; Ploehn, H. J.

This paper explores the effect of nanodiamond (ND) surface chemistry on the structure and properties of composites of ND melt-blended with poly(ether-ether-ketone) (PEEK). ND functionalized with phenylphosphonate (PPA) resulted in ND/PEEK composites with improved filler dispersion based on visual observations and surface topography measurements. As-received oxidized ND (OND) reduces PEEK's…

Adjuvants Based on Synthetic Mycobacterial Cord Factor Analogues: Biophysical Properties of Neat Glycolipids and Nanoself-Assemblies with DDA

Kallerup, Rie S.; Franzyk, Henrik; Schiøth, Mikkel L.; Justesen, Sarah; Martin-Bertelsen, Birte; Rose, Fabrice; Madsen, Cecilie M.; Christensen, Dennis; Korsholm, Karen S.; Yaghmur, Anan; Foged, Camilla

Synthetic mycobacterial cord factor analogues, e.g., trehalose 6,6′-dibehenate (TDB), are highly promising adjuvants due to their strong immunopotentiating capabilities, but their biophysical properties have remained poorly characterized. Here, we report the synthesis of an array of synthetic TDB analogues varying in acyl chain length, degree of acylation, and headgroup display,…

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…

Smectic liquid crystal Schlieren texture in rapidly cooled poly(butylene naphthalate)

Ding, Qian; Jehnichen, Dieter; Göbel, Michael; Soccio, Michelina; Lotti, Nadia; Cavallo, Dario; Androsch, René

The morphology of partially crystalline/ordered poly(butylene naphthalate) (PBN) forming on cooling the melt has been analyzed by polarized-light optical microscopy (POM) and microfocus-beam X-ray diffraction (XRD). Crystallization at rather low supercooling of the melt, at temperatures higher than about 200 °C, leads to slow and irregular spherulitic growth of β′-crystals, with…

Amphiphilic diblock copolymer-mediated structure control in nanoporous germanium-based thin films

Hohn, Nuri; Hetzenecker, Andreas E.; Giebel, Michael A.; Geier, Sebastian; Bießmann, Lorenz; Körstgens, Volker; Saxena, Nitin; Schlipf, Johannes; Ohm, Wiebke; Deimel, Peter S.; Allegretti, Francesco; Barth, Johannes V.; Roth, Stephan V.; Fässler, Thomas F.; Müller-Buschbaum, Peter

Fabrication of porous, foam-like germanium-based (Ge-based) nanostructures is achieved with the use of the amphiphilic diblock copolymer polystyrene-b-polyethylene oxide as structure directing agent. Basic concepts of block copolymer assisted sol–gel synthesis are successfully realized based on the 4− Zintl clusters as a precursor for Ge-based thin films. Material/elemental composition and…

Highly Entangled α-Olefin Molecular Bottlebrushes: Melt Structure, Linear Rheology, and Interchain Friction Mechanism

López-Barrón, Carlos R.; Tsou, Andy H.; Hagadorn, John R.; Throckmorton, Joseph A.

Linear viscoelastic response and melt microstructure of ultra-high molecular weight poly(α-olefins) (UHMW PO) with bottlebrush architectures, from poly(1-hexene) to poly(1-octadecene) synthesized by metal coordinative insertion polymerization, were measured as a function of side-chain length, Nsc. All these bottlebrush POs are highly entangled, with an average number of entanglements per chain,…

Polymer nanocomposites: Insights on rheology, percolation and molecular mobility

Nadiv, Roey; Fernandes, Ricardo M. F.; Ochbaum, Guy; Dai, Jing; Buzaglo, Matat; Varenik, Maxim; Biton, Ronit; Furó, István; Regev, Oren

The integration of carbon nanotubes (CNTs) into a polymer matrix strongly affects the rheological behavior that in turn may hamper the overall performance of the resulting composite. Research in this topic has focused on bulk rheological properties, while here we employ NMR diffusion experiments to explore the mobility (diffusivity) of…

Thermomechanical and Conductive Properties of Thiol–Ene Poly(ionic liquid) Networks Containing Backbone and Pendant Imidazolium Groups

Bratton, Abigail F.; Kim, Sung-Soo; Ellison, Christopher J.; Miller, Kevin M.

A series of covalently cross-linked poly(ionic liquid) networks were prepared using thiol–ene “click” photopolymerization. In these networks, imidazolium groups are placed in the backbone and pendant to the main chain, creating a “hybrid”-type network architecture. The pendant imidazolium groups were incorporated into the networks from monofunctional “ene” monomers that contained…

Photocatalytic degradation of bisphenol A induced by dense nanocavities inside aligned 2D-TiO2 nanostructures

Bakardjieva, Snejana; Fajgar, Radek; Jakubec, Ivo; Koci, Eva; Zhigunov, Alexander; Chatzisymeon, Efthalia; Davididou, Konstantina

The preparation of materials with aligned porosity in the nanometer range is of technological importance for a wide range of applications in molecular filtration, biomaterials and catalysis. Herein we present the advantages offered by cryo – lyophilisation technique as a smart and green non-standard concept to produce dense regular polyhedral…
