- Abstract
- Block copolymers (BCPs) have been investigated for fabricating functional nanomaterials due to their properties of self-assembly. We prepared polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP) lamellar films which is hydrophobic block-hydrophilic polyelectrolyte block polymer have 57 kg/mol-b-57kg/mol. The lamellar stacks are obtained by exposing the spin coated film under chloroform. The P2VP blocks were then quaternized and crosslinked to various extents using 5wt% of iodomethane.The quarternized films with thickness varied from 0.43 mu m (446 inn absorption maximum) to 0.25 mu m (478 nm absorption maximum). The band shift as well as scattering around 400 nm clearly suggests that the each layer thickness changed accompanying with the roughness of the layer interfaces.
