Abstract
A method of forming a microphase separated block copolymer includes exposing a block copolymer to acid vapor under conditions effective to provide the microphase separated block copolymer. The block copolymer includes a first hydrophobic block and a second hydrophobic block that is acid-sensitive. The microphase separated block copolymer includes the first hydrophobic block and a hydrophilic block derived from the second hydrophobic block. Exposing the block copolymer to the acid vapor is conducted in the solid state.
