Characterization of functionalized coatings prepared from pulsed plasma polymerization

Material assembly based on elastomer part and metallic substrate has been widely used in many industrial sectors. However, the adhesion between two materials requests specific processes adhesives. Plasma technology is an interesting way to prepare since plasma polymer layers for adhesive joint can bear different reactive chemical functions toward elastomer. Three coatings are synthesized from acetylene, acrylic acid, maleic anhydride because of their respective able open carbon-carbon double bond (rubber, fluoroelastomer). For such a purpose, fine-tuning parameters was essential preserve precursor chemistry avoid any degradation. Pulsed discharge selected, defined thanks design experiment. The polymers were characterized by FTIR, XPS NEXAFS spectroscopies surface energy measurement.
