An effective pretreatment of polymers is crucial for achieving a good
adhesion of metal coatings to the substrate. We have characterised the
individual stages bf a swell and etch treatment of epoxy resins with
a variety of techniques, Scanning force microscopy (SFM) investigation
s have enabled an quantitative assessment of the swelling and chemical
etching of the polymer. Information about the chemistry of the proces
s has been obtained using gravimetric measurements, photoelectron and
infrared spectroscopy.
