Microphase Separation of a PS-b-PFS Block Copolymer via Solvent Annealing: Effect of Solvent, Substrate, and Exposure Time on Morphology
Block copolymer (BCP) lithography makes use of the microphase separation properties of BCPs to pattern ordered nanoscale features read more over large areas.This work presents the microphase separation of an asymmetric polystyrene-block-poly(ferrocenyl dimethylsilane) (PS-b-PFS) BCP that allows ordered arrays of nanostructures to be formed by spin
