1. A liquid formulation having a barrier property, comprising:
a suspension of nanocellulose (NC) elements in a liquid medium, wherein the NC elements comprise at least one of cellulose nanofibers and cellulose microfibers,
a drying/dispersal additive, wherein the drying/dispersal additive is a lower critical solution temperature (LCST polymer), and
a barrier-producing material having selected from the group consisting of an oil and grease resistant (OGR) property, a water resistant (WVR) property and a combination of both a water resistant (WVR) property, wherein the barrier-producing material comprises cellulose acetate;
and wherein the cellulose nanofibers have a diameter between about 4 nm and about 20 nm and the cellulose microfibers have a diameter between about 20 nm and about 100 nm.
