We demonstrate that the combination of linear and branched poly(ionic liquid)s (PILs) with network-forming materials can guide the formation of hybrid ionogels with large-scale continuous percolated morphology. Nanocelluloses (cellulose nanocrystals and nanofibers) are used as network-forming materials since they construct interconnected network structure where PILs can be incorporated, forming robust functional gels in a scalable manner. The complexation of multifunctional PILs with nanocellulose in ionic liquids facilitates the assembly of hybrid large-scale ionogels based on large-scale percolating networks of nanocelluloses serving as the supporting “frame” for continuous ionophilic network and multifunctional PILs providing the ability to control over morphology and properties. Additionally, PIL-wrapped nanofibers form PIL-nanofibrillar network with potentially intriguing meso- and macroscopic morphology and enhanced flexibility.
