Abstract
A method of producing a structure having a polymer surface with a plurality of surface domains, the surface being formed by the steps of: forming a liquid composition comprising at least one surface polymer, at least one block copolymer and at least one common solvent, the at least one block copolymer having the general formulae A-B-C, wherein A is a polymer which is the same as the surface polymer or fully miscible or partially immiscible with the surface polymer; B is a polymer which is more immiscible in the surface polymer than polymer A; and C is a terminal group; and solidifying the liquid composition to form the structure having the surface with the plurality of surface domains.
Claims13
A polymer structure comprising a surface formed substantially from a surface polymer and being nano-patterned with a plurality of functionalised surface domains extending from or formed in the surface of the surface polymer, the functionalised surface domains being formed by solidifying a block copolymer of the general formulae A-B-C, wherein
- A is a polymer which is the same as the surface polymer or fully miscible or partially immiscible with or substantially miscible in the surface polymer;
- B is a polymer which is more immiscible in the surface polymer than polymer A;
- and
- C is a terminal group;
- and wherein
- the surface domain includes the B block and the C group, with the A block being substantially embedded in the surface polymer and the C group includes a moiety selected from the group consisting of (male)imides, —COOH, —SH, —SO42−, PO43−, —NH3, -vinyl sulphone, -epoxy, -alkyne, -hydrazide, -aldehyde, —C(CH3)3, —C6F5, cell binding domains from extracellular matrix molecules, a small molecule or moiety that has biofunctionality and a small molecule or moiety that can interact with other molecules that have biofunctionality.
