Title: Low-temperature ordering effects in diblock copolymer melts from lattice simulation

Source: Journal of Chemical Physics

Year : 2004

Abstract:

A lattice simulation of a model diblock copolymer melt is presented. In a series of simulation experiments an 8-8 diblock melt is quenched from an athermal state to 47 lower temperatures. A set of simulation boxes, 30x32x30, 40x32x60, 50x32x30, and 60x32x30, is used in order to explore the size effects. Energy, specific heat, copolymer end-to-end distance, lamellar spacing, and the degree of interfacial ordering are reported. For all sizes considered, the low-temperature interfacial ordering is noticeable.
