Multi-continuous network nature of polymer nanostructures makes them afford many opportunities to fabricate multifunctional materials with specific mechanical, transport, optical, and other novel properties. In this paper, we generate an effective design principle to craft a serial of multi-continuous network structures with controllable channels, including multi-continuous gyroid and O70 network morphologies via the self-assembly of ABC type block copolymers. Importantly, we achieve a much wider (~25%) compositional range than that of AB diblock copolymer (~3%), which would increase the widespread application of these multi-continuous polymer networks. Even for the simplest ABC linear system, this method is valid for generating multi-continuous network structures, where gyroid and O70 are found to possess large phase regions. This finding can theoretically explain the experimental observation of gyroid and O70 phases. We believe that our proposed design principle along with the calculated phase diagram provides a compelling panacea for the fabrication of multi-continuous 3D network nanostructures.
