Plasma polymer for enhancing adhesion bonds of metal/elastomer assembly
Résumé
Four model plasma coatings obtained with selected parameters and precursors (acetylene,
acrylic acid and maleic anhydride) were developed for the preparation of adhesive joints of metal
/ elastomer assembly. One of these layers, PW, is thin and highly functionalized while another
(CW) coated with the same thickness is less functionalized but crosslinked. The two other layers
(CW x 2, CW + PW), twice as thick compared to PW and CW, show the same chemical criteria.
The adhesion strength of prepared assemblies is increasing but mostly depends on the precursor
type. Moreover, such model layers allow to study the adhesion mechanism between the metal and
the elastomer. The thermodynamic adhesion, i.e. surface energy closer to the elastomer one appears
to prevail.
