Graphical Abstract

Thumbnail image of graphical abstract

Neutral brush layers are prepared from a ternary blend of two low-molecular-weight homopolymers and their corresponding low-molecular-weight block copolymer. The presence of block copolymer effectively emulsifies the homopolymer mixtures on substrates and mediates their grafting ratios.
