A New Insight into the Isotropic - Nematic Phase Transition in Lyotropic Solutions of Semiflexible Polymers: Density-Functional Theory Tested by Molecular Dynamics

04-May-2016 | Sergei Egorov; Andrey Ivanov Milchev; Peter Virnau; Kurt Binder, Soft Matter, 2016

Semiflexible polymers in solution are studied for a wide range of both contour length $L$ and persistence length $\ell_p$ as function of monomer concentration under good solvent conditions. Both density-functional theory (DFT) and Molecular Dynamics (MD) simulation methods are used, and very good ...

Functional Porous Composites by Blending with Solution-Processable Molecular Pores

26-Apr-2016 | Shan Jiang; Lin Chen; Michael E. Briggs; Tom Hasell; Andrew Cooper, Chemical Communication, 2016

We present a simple method for rendering non-porous materials porous by solution co-processing with organic cage molecules. This method can be used both for small functional molecules and for polymers, thus creating porous composites by molecular blending, rather than the traditional approach of ...

Illumination of Conjugated Polymer in Solution Alters Its Conformation and Thermodynamics

20-Apr-2016 | Brian Morgan; Mark D. Dadmun, Macromolecules, 2016

The importance of chain structure in conjugated polymer-based material active layers and its relation to device efficiencies in OPVs, organic field transistors, OLEDs, and other devices has been well established. However, the influence that the absorbance of the light inherent to these devices ...

Increased production of nanofibrous materials by electroblowing from blends of hyaluronic acid and polyethylene oxide

15-Apr-2016 | Marek Pokorny, Vladimir Rassushin, Lucie Wolfova, Vladimir Velebny, Polymer Engineering and Science, 2016

Natural and synthetic nanostructured polymers in the form of fibers are used in medical and cosmetic applications. One of the main advantages of the electrospinning method is its flexibility, which allows to use airflow in the vicinity of a spinneret to increase production. The acceleration of ...

Influence of support layer and PDMS coating conditions on composite membrane performance for ethanol/water separation by pervaporation

14-Apr-2016 | Parimal V Naik, Roy Bernstein, Ivo F. J Vankelecom, Journal of Applied Polymer Science, 2016

ABSTRACT A systematic study was performed on the combination of support properties and polydimethylsiloxane (PDMS) coating conditions for the lab‐scale preparation of a defect‐free, thin film composite membrane for organophilic pervaporation. Support layers having comparable surface porosities ...

Synthesis and characterization of poly (acrylonitrile‐co‐acrylic acid) as precursor of carbon nanofibers

13-Apr-2016 | Ezgi Ismar, A. Sezai Sarac, Polymers for Advanced Technologies, 2016

Synthesis of a co‐polymer of polyacrylonitrile (PAN) producing a carbon nanofiber out of PAN and co‐polymer of PAN and comparison between these products were examined. Free‐radical solution copolymerization of acrylonitrile (AN) with acrylic acid (AA) was studied. In this perspective, AA, and AN ...
