Phase behavior of medium and high internal phase water-in-oil emulsions stabilized solely by hydrophobized bacterial cellulose nanofibrils
Water-in-oil emulsions stabilized solely by bacterial cellulose nanofibers (BCNs), which
were hydrophobized by esterification with organic acids of various chain lengths (acetic
acid, C2-; hexanoic acid, C6-; dodecanoic acid, C12-), were produced and characterized.
When using freeze-dried C6-BCN and C12-BCN, only a maximum water volume fraction
(ϕw) of 60% could be stabilized, while no emulsion was obtained for C2-BCN. However, the
maximum ϕw increased to 71%, 81%, and 77% for C2-BCN, C6-BCN, and C12-BCN …
