Polymer dispersions คือ
WebConductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. [1] [2] Such compounds may have metallic conductivity or can be semiconductors. The biggest advantage of conductive polymers is their processability, mainly by dispersion. WebApr 11, 2002 · Aqueous polymer dispersions are environmentally friendly and therefore they have replaced in many applications polymers dissolved in organic solvents. This substitution process is still ongoing. This book discusses the world of aqueous polymer dispersions from the viewpoint of how they are applied.
