Mesoscale modeling of block copolymer nanocomposites

Abstract

Nanoadditives alter the properties of pure block copolymers, through an interplay of entropic, enthalpic and kinetic factors at competing length and time scales. A fundamental understanding of these factors is considered decisive for taming block copolymer nanocomposites, since even modest changes in design parameters can impact the final material. At the same time, analytical and computational approaches have not yet reached the maturity required for an integrated study of all relevant aspects. Heterogeneity, local irregularities and dynamic behavior—these are the most challenging issues facing theory and simulations in the quest for rational design. In this review, we discuss the state of mesoscopic modeling for block copolymer nanocomposites, and cover relevant literature from at least the last five years, during which developments have taken off.
