GERMAN SCIENTISTS DEVELOP CO2 DYE FIXING RESEARCH
February 2nd, 2011
BY KEITH NUTHALL
GERMANY'S Fraunhofer Institute for Environmental, Safety and Energy Technology has been testing how carbon dioxide at 30.1 Celsius and a pressure of 73.8 bar can become an effective dye carrier. It then "goes into a supercritical state that gives the gas solvent-like properties," said an institute note, and can be introduced into polymers. Also dyes, additives, medical compounds and other substances can be dissolved into it.
