Abstract
Disclosed herein is a graft block copolymer comprising a first block polymer; the first block polymer comprising a backbone polymer and a first graft polymer; where the first graft polymer comprises a surface energy reducing moiety; and a second block polymer; the second block polymer being covalently bonded to the first block; wherein the second block comprises the backbone polymer and a second graft polymer; where the second graft polymer comprises a functional group that is operative to crosslink the graft block copolymer.
Claims10
A graft block copolymer comprising:
- a first block polymer;
- the first block polymer comprising a backbone polymer and a first graft polymer;
- where the first graft polymer comprises a surface energy reducing moiety;
- and
- a second block polymer;
- the second block polymer being covalently bonded to the first block;
- wherein the second block comprises the backbone polymer and a second graft polymer;
- where the second graft polymer comprises a functional group that is operative to crosslink the graft block copolymer.
An article comprising:
- a crosslinked graft block copolymer having a cylindrical morphology, where the graft block copolymer comprises a first block polymer;
- the first block polymer comprising a backbone polymer and a first graft polymer;
- where the first graft polymer comprises a surface energy reducing moiety;
- and a second block polymer;
- the second block polymer being covalently bonded to the first block;
