Figure 1: (a) Ring shape structures of PFS domains from PS-PFS-P2VP triblock terpolymer films. (b) A square-array of PFS posts from a PI-PS-PFS triblock terpolymer blended with 18% homopolymer PS. This blended film deposited on substrates patterned with shallow trenches, after a chloroform solvent anneal. The orientation of the array depends on the functionalization of the substrate.
