PES/Quaternized-PES Blend Anion Exchange Membranes: Investigation of Polymer Compatibility and Properties of the Blend
Polyethersulfone (PES)-based anion exchange blend membranes were prepared from quaternized-PES (Q-PES) and N-Methyl-2-pyrrolidone (NMP) casting solutions with water as coagulant via non-solvent induced phase inversion. The compatibility of the blend system was investigated through thermodynamic studies while membrane formation was determined using the cloud point techni...
متن کاملImproving power efficiencies in polymer—polymer blend photovoltaics
The use of blends of electron and hole transporting polymers has been shown to increase exciton dissociation and efficiency in polymer-based photovoltaics. We compare plain M3EHPPV devices to M3EH-PPV:CN-ether-PPV blend devices, demonstrating the improved performance of blends. We vary the polymer layer thickness and device electrodes for M3EHPPV:CN-ether-PPV polymer blend devices to investigat...
متن کاملInterdiffusion in a polydisperse polymer blend.
We present a theoretical description of interdiffusion in a binary blend of polymers that exhibit polydispersity in length. The diffusion equations are formulated in terms of the volume fractions and the chain concentrations of the components. This choice of variables is equivalent to the assumption that the local molecular weight distributions of the components are described by the Flory distr...
متن کاملWaste Management Trends in the Paint Manufacturing Industry
T h e paint industry makes a variety of products that preserve, protect and enhance the objects to which they are applied. Although the post-consumer residuals of these products are usually labeled non-hazardous, they have often been termed “environmentally unfriendly” as has the industry responsible for creating them. With 1,400 manufacturing plants and an output of more than 1.1 billion gallo...
متن کاملRelease of theophylline from polymer blend hydrogels.
Polymer blending is a simple yet attractive method to obtain combined physical and mechanical properties of polymers. In this paper, three types of blend hydrogels were prepared, each by physically blending two different natural polymers, and a model drug, theophylline (TPH), was immobilized into these hydrogels for the studies of drug release. The release profiles of TPH from various types of ...
