Local v/a variations as a measure of structural packing frustration in bicontinuous mesophases, and geometric arguments for an alternating Im3m (I-WP) phase in block copolymers with polydispersity

Abstract

This article explores global geometric features of bicontinuous space-partitions and their relevance to self-assembly of block-copolymers. Using a robust definition of 'local channel radius', based on the concept of a medial surface [Schröder et al., Eur
