  • Thermally reversible cross-linked poly(aryl ether ketone) media and method for high density data storage
    Patent number: 8604135
    Abstract: A composition of matter for a recording medium in atomic force data storage devices. The composition includes one or more poly(aryl ether ketone) copolymers, each of the one or more poly(aryl ether ketone) copolymers including (a) a first monomer including an aryl ether ketone and (b) a second monomer including an aryl ether ketone and a hydrogen bonding cross-linking moiety, the moiety capable of forming two or more hydrogen bonds at room temperature, each of the one or more poly(aryl ether ketone) copolymers having two terminal ends, each terminal end having a phenylethynyl moiety. The covalent and hydrogen bonding cross-linking of the poly(aryl ether ketone) oligomers may be tuned to match thermal and force parameters required in read-write-erase cycles.
