Using dissipative particle dynamics simulations, we document the long-time trapping of a single bicontinuous, disordered network phase for a semiflexible diblock copolymer with a persistence length commensurate with the block contour length. The equilibrium lamellar phase is recovered upon subsequent thermal cycling near the equilibrium order–disorder condition. These insights suggest that a disordered network phase could be realized via the controlled cooling of a bottlebrush diblock copolymer melt possessing a modest backbone degree of polymerization. 2026-09-29T00:00:00Z Text Journal contribution 10.1021/acsmacrolett.6c00373.s001 https://figshare.com/articles/journal_contribution/Trapped_Topologies_in_Semiflexible_Diblock_Copolymer_Melts/34028618 CC BY-NC 4.0
