pH-triggered phase inversion and separation of hydrophobised bacterial cellulose stabilised Pickering emulsions
Reactive & functional polymers
The pH-triggered transitional phase behaviour of Pickering emulsions stabilised by hydrophobised bacterial cellulose (BC) is reported in this work. Neat BC was hydrophobised via esterification with acetic (C 2 -), hexanoic (C 6 -) and dodecanoic (C 12 -) acids, respectively. We observed that C 6 -and C 12 -BC stabilised emulsions exhibited a pH-triggered reversible transitional phase separation. Water-in-toluene emulsions consisting of 60 vol.-% dispersed phase stabilised by C 6 -and C 12 -BCdoi:10.1016/j.reactfunctpolym.2014.09.016 fatcat:6ipmf7h4f5borfb2eh265bvkoy
