1. A composite for forming a coacervate interfacial film, the composite comprising:
a cationic hectorite nanoplate particle structure containing a hectorite nanoplate particle and a cationic surfactant coupled to a surface of the hectorite nanoplate particle; and
an anionic cellulose nanofibril containing an anionic functional group in at least a portion thereof,
wherein the composite forms the coacervate interfacial film at an interface of an oil phase and a water phase through electrostatic interaction between the cationic surfactant and the anionic functional group.
