ESD protection materials using conductive polymers

Clear conductive polymer films were prepared by coating the solution composed of conductive polymer and their properties were evaluated. Conductive polymer coated polymer films are transparent and have good ESD properties enough to be used as ESD protection materials for packaging electronic parts. 0.5 mm thick A-PET film with a surface resistance of 10⁵ ohms per square shows a transparency at 550 nm of higher than 80%. Other properties such as cleanliness were also described. In addition, the application to other products such as cover films for carrier tapes, interleaf films for flexible printed circuit boards are introduced.
