Topological Effects on Blend Miscibility

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

New patterns of polymer blend miscibility associated with monomer shape and size asymmetry

Polymer blends are formulated by mixing polymers with different chemical structures to create new materials with properties intermediate between those of the individual components. While Flory– Huggins ~FH! theory explains some basic trends in blend miscibility, the theory completely neglects the dissimilarity in monomer structures that is central to the fabrication of real blends. We systemati...

Interdiffusion of PCBM and P3HT Reveals Miscibility in a Photovoltaically Active Blend

Developing a better understanding of the evolution of morphology in plastic solar cells is the key to designing new materials and structures that achieve photoconversion effi ciencies greater than 10%. In the most extensively characterized system, the poly(3-hexyl thiophene) (P3HT):[6,6]-phenyl-C 61 -butyricacid-methyl-ester (PCBM) bulk heterojunction, the origins and evolution of the blend mor...

Miscibility and influence on each other of a UV photo-initiated thermosetting polymer blend of radical and cationic systems

Lefebvre, Kevin, "Miscibility and influence on each other of a UV photo-initiated thermosetting polymer blend of radical and cationic systems" (2013). Thermoset blends engage an interest into polymer materials using photopolymerization. Our work is inscribed within a project which consists to control the degree of crosslinking in three dimensions during UV photo-curing. Two different reaction m...

Influence of Phase Behavior and Miscibility on Mechanical, Thermal and Micro-Structure of Soluble Starch-Gelatin Thermoplastic Biodegradable Blend Films

Polymer blends of cold water soluble starches (amylose or amylopectin soluble starch) with gelatin were prepared using solvent casting method. The solid state miscibility and polymer-polymer interactions between the constituent polymers were studied by fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorirmetry (DSC), light optical microscopy (OP...
