TL;DR: In this article, the authors investigated the effects of viscosity ratio, blend composition, and processing variables (temperature, rotor speed, and mixing time) on the evolution of blend morphology in five blend systems: (i) nylon-6/high-density polyethylene (HDPE), (ii) poly(methyl methacrylate) (PMMA)/polystyrene (PS), (iii) polycarbonate (PC)/PS, (iv) PS/HHPE, and (v) polypropylene (PP).

TL;DR: In this article, a mixture of polyvinylidene fluoride/nylon-6 (PVDF/N6) 30:70 was melt compounded with various organoclays directly or sequentially.
Abstract: Blends of poly(vinylidene fluoride)/nylon-6 (PVDF/N6) 30:70 were melt compounded with various organoclays directly or sequentially. The morphology, thermal, and mechanical properties of the blend nanocomposites were investigated. It was determined that the degree of compatibilization induced by the nanoclay particles was dependent on the location of the particles and the degree of clay dispersion. The blend nanocomposite with the best mechanical properties had good dispersion of particles throughout the matrix (N6) and at the PVDF/N6 interface. In this blend nanocomposite, the coalescence of PVDF domains was prevented, and the crystallization of the PVDF domains was suppressed, ultimately creating a blend nanocomposite that is stiffer, stronger, and tougher than the blend without nanoparticles.

TL;DR: A model system for blend polymers with electron-donating and -accepting compounds found that the optimal energy conversion efficiency can be achieved when the feature size is around 10 nm, and the dependency of PCE on the charge mobility and the material structure is investigated.
Abstract: We developed a model system for blend polymers with electron-donating and -accepting compounds. It is found that the optimal energy conversion efficiency can be achieved when the feature size is around 10 nm. The first reaction method is used to describe the key processes (e.g., the generation, the diffusion, the dissociation at the interface for the excitons, the drift, the injection from the electrodes, and the collection by the electrodes for the charge carries) in the organic solar cell by the dynamic Monte Carlo simulation. Our simulations indicate that a 5% power conversion efficiency (PCE) is reachable with an optimum combination of charge mobility and morphology. The parameters used in this model study correspond to a blend of novel polymers (bis(thienylenevinylene)-substituted polythiophene and poly(perylene diimide-alt-dithienothiophene)), which features a broad absorption and a high mobility. The I−V curves are well-reproduced by our simulations, and the PCE for the polymer blend can reach up t...

TL;DR: Alginate/carboxymethyl chitosan blend fibers, prepared by spinning their mixture solution through a viscose-type spinneret into a coagulating bath containing aqueous CaCl2, were studied for structure and properties with the aid of infrared spectroscopy, X-ray diffraction, and scanning electron micrography as discussed by the authors.
