Abstract

A novel method for controlling the orientation of PSt-b-PMMA block copolymer thin films by using hydrophilic nanoparticles without the need for a neutralization layer that greatly improves the processability of PSt-b-PMMA systems has been demonstrated. It has been shown that the incorporation of hydrophilic PEO-coated nanoparticles into poly(styrene-b-methyl methacrylate) (PSt-b-PMMA) diblock copolymers, the ordering of PSt-b-PMMA thin films can be effectively controlled in a manner that is similar to the PEO-based block copolymer, while retaining the degradability of the PMMA domains. The effect of hydrophilic PEO-coated Au particles on the domain size and its homogeneity of PMMA cylinders within a PS domain is demonstrated, although the nanoparticle itself introduce a secondary functionality such as etch resistance into the films.
