Specific Interaction between Components In Polymer Blend

Effective interaction between monolayers of block copolymer compatiblizer in a polymer blend

Influence of solvent/polymer interaction on miscibility of PMMA/PCL blend: thermal analysis approach

Improving 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...

Interdiffusion 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...

Release 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 ...
