Claim 12:
13. A method of activating a surface of a plastics substrate formed from:
(a) a polyaryletherketone;
(b) a polymer containing a phenyl group directly attached to a carbonyl group, optionally wherein the carbonyl group is part of an amide group;
(c) polyphenylene sulfide (PPS); or
(d) polyetherimide (PEI);
for subsequent bonding,
the method comprising a step of exposing the surface to actinic radiation wherein the actinic radiation:
includes radiation with wavelength in a range from about 10 nm to about 1000 nm;
and energy of the actinic radiation to which the surface is exposed is in a range from about 0.5 J/cm2 to about 300 J/cm2, the method comprising the step of treating the surface with copper acrylate, prior to exposing the surface to actinic radiation.
