Aggregation, gelation instability, and morphologies of diblock copolymers consisting of poly(p‐benzamide) and poly(m‐benzamide)

01-Aug-2010 | Kataoka, Toshiyuki; Ohishi, Tomoyuki; Yokozawa, Tsutomu; Ikehara, Takayuki, Journal of Polymer Science Part B: Polymer Physics, 2010

The solution, gelation, and morphological properties of monodisperse aromatic polyamide diblock copolymers consisting of poly(p-benzamide) (PpBA), poly(m-benzamide) (PmBA), and poly(N-octyl m-benzamide) (POmBA) were investigated. The block copolymers of these polymers, PpBA-block-POmBA and ...


A novel pH‐ and thermo‐sensitive PVP/CMC semi‐IPN hydrogel: Swelling, phase behavior, and drug release study

01-Aug-2010 | Lü, Shaoyu; Liu, Mingzhu; Ni, Boli; Gao, Chunmei, Journal of Polymer Science Part B: Polymer Physics, 2010

Poly(N-vinyl-pyrrolidone) (PVP) hydrogel has been considered as a very interesting and promising thermosensitive material. The most vital shortcoming of PVP hydrogel as thermosensitive material is that it does not exhibit thermosensitivity under usual conditions. In this work, ...


Secondary relaxations and electrical conductivity in hyperbranched polyester amides

15-Jul-2010 | Turky, G.; Sangoro, J. R.; Abdel Rehim, M.; Kremer, F., Journal of Polymer Science Part B: Polymer Physics, 2010

Broadband dielectric spectroscopy is used to investigate molecular dynamics and charge transport in three hyperbranched polyester amides with hydroxyl, phenyl, and stearate terminal groups. At higher temperatures, the dielectric spectra are interpreted in terms of hopping conduction in a ...


Structure and dynamics of polymer chains in hydrophilic nanocomposites

15-Jul-2010 | Fotiadou, S.; Chrissopoulou, K.; Frick, B.; Anastasiadis, S. H., Journal of Polymer Science Part B: Polymer Physics, 2010

Poly(hexa(ethylene glycol) methacrylate)/sodium montmorillonite, (PHEGMA/Na+-MMT) nanocomposites with varying composition were synthesized utilizing melt intercalation and solution mixing. Intercalated hybrids were obtained but, for the solution prepared hybrids, the equilibrium structure could ...


Investigation of structural changes in semi‐crystalline polymers during deformation by synchrotron X‐ray scattering

15-Jul-2010 | Schneider, Konrad, Journal of Polymer Science Part B: Polymer Physics, 2010

The mechanical behavior of polymer materials is strongly dependent on polymer structure and morphology of the material. The latter is determined mainly by processing and thermal history. Temperature-dependent on-line X-ray scattering during deformation enables the investigation of deformation ...


PS‐b‐PEO block copolymer thin films as structured reservoirs for nanoscale precipitation reactions

15-Jul-2010 | Ochsmann, Jannis W.; Lenz, Sebastian; Emmerling, Sebastian G. J.; Kappes, Ralf S.; Nett, Sebastian K.; Lechmann, Mar ..., Journal of Polymer Science Part B: Polymer Physics, 2010

Thin films of PS-b-PEO block copolymers were utilized as structured reservoirs for localized nanoscale precipitation reactions. By consecutively immersing the film into solutions of thioacetamide and cadmium chloride, we were able to obtain a monolayer of cadmium sulfide nanostructures on top of ...


Fabrication of polymeric nano‐objects using PS5P2VP5 heteroarm star copolymers as building elements

15-Jul-2010 | Tasis, Dimitrios; Tsitsilianis, Constantinos, Journal of Polymer Science Part B: Polymer Physics, 2010

This work is focused on the self-organization of an heteroarm star copolymer consisting of 5 polystyrene and 5 poly(2-vinylpyridine) (P2VP) arms emanated from a poly(divinyl benzene) core and the chemical stabilization of the resulting supramolecular nano-objects in the bulk and in solution. To ...


Gradient and patterned polymer brushes by photoinitiated “grafting through” approach

15-Jul-2010 | Enright, Timothy P.; Hagaman, Daniel; Kokoruz, Maryana; Coleman, Natalia; Sidorenko, Alexander, Journal of Polymer Science Part B: Polymer Physics, 2010

More than 2 decades of active investigations in the field of polymer brushes have revealed continuous and growing interest in different aspects of synthesis, properties, and applications of tethered polymers. In this article, we report on our recent advances in brush synthesis. The method we ...


Combinatorial approach for fast screening of functional materials

15-Jul-2010 | Walter, Harald; Basset, Guillaume; Beierlein, Tilman; Von Mühlenen, Adrian; Nisato, Giovanni, Journal of Polymer Science Part B: Polymer Physics, 2010

We present an integrated system with automated sample fabrication for combinatorial investigations of solution-processed organic materials. To illustrate the applicability of the system, we give examples of typical experimental results with organic electronic devices. Organic light emitting ...


Fabrication of functional nano‐objects via self‐assembly of nanostructured hybrid materials

15-Jul-2010 | Pietsch, Torsten; Gindy, Nabil; Mahltig, Boris; Fahmi, Amir, Journal of Polymer Science Part B: Polymer Physics, 2010

A simple route to fabricate functional nano-objects via self-assembly of block copolymer-based hybrid materials is described. In water-toluene mixtures, spheres, rod-like morphologies, and ring-like morphologies as well as vesicles of metal loaded block copolymers micelles are fabricated. The ...
