Microphase separated block copolymer electrolyte (BCE) systems are attractive candidates for electrochemical systems because the concentrated ionic groups in one block provide pathways for facile ion transport while the non-ionic block bestows mechanical integrity and suppresses excess water uptake. Numerous researchers have prepared and studied bulk BCEs as ion conductors, but these materials inherent complex nature and imprecise architecture makes it difficult to extract definitive conclusions how the macromolecular structure influences ion transport. In this work, the process of block copolymer lithography was demonstrated to create model nano-confined polymer electrolyte brushes that mimic lamellae structures found in bulk BCE membranes. Both nano-confined anion and cation conducting polymer brushes were prepared and excellent ionic conductivities (10-2 S cm-1 to 10-1 S cm-1) were obtained.
