Patent ID: 8169882

Claim:
A method, comprising: forming a layer of a polyaryletherketone polymer on a substrate, said polyaryletherketone polymer comprising a first repeat unit, a second repeat unit, a first terminal end and a second terminal end, said first repeat unit including an aryl ketone monomer, said second repeat unit including a monomer having a first phenylethynyl moiety, said first terminal end having a second phenylethynyl moiety and said second terminal end having a third phenylethynyl moiety; heating said layer of polyaryletherketone polymer to form a layer of a polyaryletherketone resin, said polyaryletherketone resin cross-linked by cyclo-addition reactions of said phenylethynyl moieties; and bringing a thermal-mechanical probe heated to a writing temperature of greater than about 100° C. into proximity with said layer of a polyaryletherketone resin multiple times to induce deformed regions at points in said layer of polyaryletherketone resin, said thermal mechanical probe heating said points in said layer of said resin and thereby writing information in said layer of polyaryletherketone resin.
