Abstract Taking advantage of the formation and assembly cellulose nanocrystal surfactants (CNCSs) at water–oil interface, where polar nanocrystals (CNCs) end‐functionalized polymer chains interact, preparation stability emulsions prepared with CNCSs were investigated. The packing density interface can be adjusted by tuning parameters such as pH, ionic strength, concentration/molecular weight ligands. Stable non‐spherical are obtained during homogenization, a result interfacial jamming CNCSs, pH‐triggered reconfigurability. Porous materials freeze‐drying creamed, CNCS‐stabilized emulsions. cells porous have controlled pore size shape that commensurate droplets in emulsion responsive to pH. behavior adaptive, reconfigurable supracolloidal system is coupled its internal surrounding environment.
