Interface morphology snapshots of vertically segregated thin films of semiconducting polymer/polystyrene blends
(Elsevier B.V., 2007-04-05)
We present atomic force microscopic images of the interphase morphology of vertically segregated thin films spin coated from two-component mixtures of poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene-vinylene] (MEH-PPV) ...

PC-SAFT equation: A predictive tool to determine experimental conditions for polymer blend demixing
(Taylor & Francis, 2009-08-06)
The perturbed-chain statistical associating fluid theory equation of state (PC-SAFT) was applied to predict the phase behavior of polymer solutions in order to determine the pressure - temperature region for the high ...
High molecular weight polymers: Supercritical solvents as blend demixing and grafting reaction medium
(Nova Science Publishers, 2014)
Near and supercritical fluids offer very interesting alternatives for separation processes, reaction medium and in the synthesis of new materials. Particularly, the applications of supercritical fluids (SCF) in the polymer ...
Nanostructured organic layers via polymer demixing for interface-enhanced photovoltaic cells
(Amer Chemical Soc, 2006-11-14)
Significant progress is being made in the photovoltaic energy conversion using organic semiconducting materials. One of the focuses of attention is the morphology of the donor-acceptor heterojunction at the nanometer scale, ...

Nanostructured organic layers via polymer demixing for interface-enhanced photovoltaic cells
(2006-12-01)
Nanostructured, semiconducting polymer films were prepared via vertical demixing of MEHPPV/ polystyrene blends during spin-coating, combined with selective dissolution. This allowed the fabrication of efficient bilayer ...
Phase diagrams of the system tetrahydrofuran/gamma-butyrolactone poly(ether imide) and determination of interaction parameters
(Elsevier Sci LtdOxfordInglaterra, 1998)
Formation and kinetics of transient metastable states in mixtures under coupled phase ordering and chemical demixing
(Europhysics Letters, 2009-12)
We present theory and simulation of simultaneous chemical demixing and phase ordering in a polymer-liquid-crystal mixture in conditions where isotropic-isotropic phase separation is metastable with respect to isotropic-nematic ...
