Abstract
A polymeric dispersant having an affinity with a supercritical fluid is provided, in which a substituent having an affinity with a supercritical fluid is attached to the terminal end of a block copolymer. The polymeric dispersant can disperse a dispersoid to particulate size by lowering surface tension between the dispersoid and the supercritical fluid to promote diffusion of the supercritical fluid into the dispersoid.
