  1. Network Constrained Surface Phase Separation Kenneth J. Wynne, Virginia Commonwealth University, DMR 0802452 Objective: Using the same fluorous surface modifier, compare morphology of linear and crosslinked base polyurethanes P-3F LinearBase PU Approach: 2 wt% modification with P-3F polyurethane. • Finding: • Soft block dominates surface chemical composition (XPS) • Crosslinked base polyurethane constrains surface phase separation of fluorous modifier P-3F Rq = 1.5 nm CrosslinkedBase PU Rq = 4.4 nm Phase Phase, z = 60 3D Height, z = 25 nm 3D Height Future: Thermal effects? Function durability? Quaternary charge stabilization?
