of OVAc-based surfactants, the process of the preparation of
X-OVAc-based surfactants was much more simple, inexpensive
and also easy to control, which could promote industrial-scale
applications. It was shown that X-OVAc-based surfactants can
effectively stabilize highly concentrated C/W emulsions. Highly
porous emulsion-templated materials with tunable cells size and
interconnected pores size were also prepared by the polymeriza-
tion of the continuous phase of C/W emulsions. The influence of
the surfactant concentration and molecular weight of OVAc
block on the morphology of the porous structures were also
investigated. The analysis by mercury intrusion porosimetry
confirms the interconnected pore size in the range of 3.2-10.0 μm

These results indicate that X-OVAc-based surfactants can out-
perform perfluorinated analogues and approach the OVAc-
based surfactants for this application. X-OVAc-based surfac-
tants may develop a range of potential applications in emulsion
technology such as the generation of biodegradable scaffolds
with highly interconnected pores suitable for tissue engineering
scaffolds.
