Synthesis and characterization of Sulfonated Poly(Styrene-Isoprene-Styrene): Effects of linear vs branched morphology and counter-ion substitution
(2009)
This investigation studied the resulting nanostructure of ionic membranes composed of sulfonated copolymers with thermoplastic and elastomeric blocks. Linear poly(styrene-isoprenestyrene) (L-SIS) and branched poly(styren ...
Perfluorinated and sulfonated proton exchange membranes: Effect of supercritical fluid processing on ion exchange capacity and proton conductivity
(2007)
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. ...
Sulfonated polymer metal nanocomposite membranes with bacterial disinfection activity in water
(2018-05)
This study describes the synthesis and characterization of sulfonated poly(styreneisobutylene-
styrene) (SIBS) polymer nanocomposite membranes, which show antibacterial
properties useful for the inactivation of Enterococci ...
Solubilities of anti-cancer and anti-AIDS drugs in supercritical carbon dioxide
(2003)
Solubility data for pharmacological drugs in supercritical fluids (SCFs) is of great
importance, because there is an environmental and cost effective need for alternative
specialty separation methods.
This research was ...
Supercritical fluid processing of sulfonated styrenic tri-block polymers
(2005)
The increasing need to replace current materials with new or reprocessed
ones that have more specific properties and uses has led to the use of supercritical
fluids (SCFs) for polymer reprocessing. Kraton® poly ...
Supercritical fluid processing of perfluorinated and sulfonated membranes
(2004)
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 ...
An evaluation of optical band gap in photovoltaic polymers for solar energy capture
(2019-05-14)
Organic solar cells are a very promising technology for use in the renewable energy field. Band gap measurements on liquid phase for different polymers were studied, and the possible radiation harvest and reasoning for ...
Brackish water desalination with a novel polymer nanocomposite membrane
(2019-04-05)
The rapid growth of the global population, the industrialization and environmental problems caused by global warming have made it necessary to implement advanced water purification techniques capable of fulfilling the ...
