Abstract:
1. A method, for use with a layer of polyaryletherketone resin on a substrate, said layer of polyaryletherketone resin formed from a polyaryletherketone copolymer, said polyaryletherketone polymer having two terminal ends, each terminal end having two or more phenylethynyl moieties, repeat units of said polyaryletherketone copolymer backbone containing ketone groups, said polyaryletherketone resin thermally cross-linked by cyclo-addition reactions of said phenylethynyl moieties of said polyaryletherketone copolymer, said method comprising: heating and bringing a thermo-mechanical device, while heated, into proximity with said layer of polyaryletherketone resin to write information into said layer of polyaryletherketone resin.
