Abstract:
High internal phase emulsion (HIPE) is a concentrated emulsion system possessing a large internal phase
volume. It can be used as a template to prepare electronic, oil spill clean-up, and controlled release materials.
However, there is limited reports on preparation of bio-based HIPE. Since the volume fraction of typical
dispersed phase is above 0.74, this results in a tendency to be unstable at high temperature. This research aims
to study the effects of surfactant systems on the HIPE stability. A novel formulation of water-in-oil bio-based
poly(HIPE)s at high-temperature synthesized conditions was also demonstrated. Epoxidized linseed oil and
oligo-chitosan solution were used as an external and internal phase, respectively. The HIPE systems were
consisted of an external/internal phase ratio of 25/75 and the selected surfactant system; including
polyoxyethylene (20) sorbitan monooleate (Tween80), polyoxyethylene (5) sorbitan monooleate (Tween81),
(Z)-sorbitan mono-9-octadecenoate (Span80), and a mixture of Tween80 and Span80, referred to as
Tween80/Span80 (weight ratio of 3/2). Emulsion morphology, including droplet size, droplet size distribution
and emulsion stability with time, were investigated. All surfactant systems could stabilize the emulsion for
more than 3 hours at room temperature. Phase separations were gradually observed in HIPE stabilized with
Tween80, Span80, and Tween80/Span80 system at 80*C. For that of Tween81, it could stabilize the emulsion
for more than 2 days. Poly(HIPE)s were prepared through a high internal phase emulsion process at 800C,
using dimer acid and epichlorohydrin as a crosslinking agent for the external and internal phases, respectively.
Poly(HIPE)s were success ssfully prepared by using Tween81 and Tween80/Span80 surfactant systems without
phase separation. The average dispersed phase size of poly(HIPE)s stabilized with Tween80/Span80, observed
under a hot-stage microscope at 300 minutes, was 11 microns, whereas that of stabilized with Tween81 was
17 microns.
