Perfluorinated and sulfonated proton exchange membranes: Effect of supercritical fluid processing on ion exchange capacity and proton conductivity
The present work has processed Nafion® and sulfonated polystyrene-isobutylenestyrene (SIBS) with supercritical fluid (SCF) carbon dioxide at a 40°C and 200 bar with the aid of ten co-solvents of different size and polarity. ...
Supercritical fluid processing of perfluorinated and sulfonated membranes
Over the past years, one of the most important challenges facing industry has been the search for environmentally benign and cost effective alternatives to traditional power sources. Many industries invest considerable ...
