Abstract

original image

This study focuses on the rapid directed nanoscale assembly of polystyrene/polymethyl methacrylate blends into complex patterns of non-uniform geometries at multiple length scales on a single template. The patterns were created using alkanethiols on gold templates (see image) patterned by dip-pen nanolithography. These chemically functionalized nanotemplates direct the nanoscale assembly of polymer blends into non-uniform patterns in short times.
