We report the phase behavior of a new class of polymer
nanocomposites, montmorillonite (MMT) block copolymer brushes
(MBBs). MBBs are comprised of discrete MMT particles encapsulated with block copolymer brushes synthesized via surface initiated atom transfer radical polymerization. Polystyrene-b-poly(n-butyl acrylate) MBBs of varying composition and total Mn = 80--250 kDa were compared with bulk block copolymers via electron
microscopy and a host of mechanical tests. MBBs were found to self
assemble into single grain morphologies across incredibly large
areas (> 3 um). Perhaps most promising is that MBBs maintain
similar melt state properties to bulk block copolymers and are thus
amenable to current processing techniques.
