The Effect of Brush Polydispersity on the Interphase between End-Grafted Brushes and Polymeric Matrices

Abstract

A self-consistent computer simulation has been used to calculate the concentration profile of an end-tethered polymer chain in a polymer matrix in order to investigate the influence of brush polydispersity on the width of the interphase. It was found that increasing the brush polydispersity increased the width of the interphase between the brush and the matrix. The results suggest that highly polydisperse brushes will result in increased adhesion when compared with an analogous brush of narrow molecular weight distribution.
