Abstract
Crosslinkable random copolymers comprising atom transfer radical polymerization (ATRP) initiators and crosslinked copolymer films formed from the copolymers are provided. The random copolymers, which are polymerized from one or more alkyl halide functional inimers and one or more monomers having a crosslinkable functionality, are characterized by pendant ATRP initiating groups and pendant crosslinkable groups.
Claims10
A crosslinked copolymer film comprising crosslinked random copolymer chains, wherein the random copolymer is a copolymer of a first monomer comprising an alkyl halide functional group that is capable of acting as an ATRP initiator, and a second monomer, and further wherein the alkyl halide functional groups are pendant groups on the backbone of the random copolymer chains and the crosslinks between the random copolymer chains are formed between crosslinkable functional groups on the second monomers.
A method of making a crosslinked copolymer film, the method comprising:
- depositing a film of a random copolymer on a substrate surface, wherein the random copolymer is a copolymer of a first monomer comprising an alkyl halide functional group that is capable of acting as an ATRP initiator and a second monomer comprising a crosslinkable functional group, and further wherein the alkyl halide functional groups and the crosslinkable groups are pendant groups on the backbone of the random copolymer chains;
- and
- subsequently crosslinking the crosslinkable functional groups, such that crosslinks are formed between the random copolymer chains in the film.
