Figure 5. (a) Measured thermal conductivity and (b) XRD of PTFE
and PES membrane.
In Figure 6, the roughness of the PES hollow fiber membrane is higher
than that of the PTFE hollow fiber membrane. The membrane surface with
high roughness and possible cavity will be easier to generate the
heterogeneous nucleation on the membrane surface. While, the increasing
surface roughness may restrain the auto-detachment motion of nucleation
from the membrane surface. This complex impact on the membrane
performance should be validated in the MACC operation59.
