Abstract
|
Aramid cords and fibers and polyester tire cords were treated by means of plasma polymerization techniques. Coatings of plasma-polymerized pyrrole or acetylene were deposited on the surface of cords and fibers in a custom-built semi-continuous reactor operated on a pulsed DC glow discharge. The deposition conditions of the plasma-polymer coatings were varied within wide limits. The cords were tested for adhesion in rubber in a industrial pull-out test. It was found that the plasma polymer coating can significantly increase pull-out forces. Coatings deposited under low power and high pressure conditions performed better than the coatings prepared under high power and low pressure conditions. The plasma-polymerized coatings were characterized by a range of analytical techniques and the performance results are explained in a tentative model based on the molecular structure of the films. The structure was found to be strongly dependent on the deposition conditions.
