Self-assembly of copper-free maltoheptaose-block-polystyrene nanostructured thin films in real and reciprocal space.
Carbohydrate Polymers(2019)
摘要
•Copper nanopowder catalyst made removal of residual copper easy after click reaction.•Improved synthetic method also help scale up the synthesis of copper-free MH-b-PS.•The microphase separation of MH-b-PS was investigated by AFM, SAXS and GISAXS.•The phase of MH-b-PS transited from Hex to Bcc when changing the annealing solvent.
