Abstract

An effect of surface treatment on adhesion behavior of poly (butylene terephthalate) (PBT) with epoxy adhesive was studied. In general, PBT is annealed at a temperature above the glass transition temperature to obtain dimensional stability for the practical use. However, such an annealing procedure makes the adhesion properties poorer. In this study, we demonstrate that tensile adhesive strength for annealed PBT could be improved through plasma treatment. Tensile adhesive strength increased with increasing surface density of C-O and COO groups, which were quantitatively detected by XPS. Finally, it was concluded that chemical interaction between carboxyl and/or ester groups of PBT and hydroxyl groups of epoxy adhesive was a responsible factor in improving adhesive strength between PBT and epoxy adhesive.
