The effect of thermo osmosis is critical to the osmosis based
renewable energy harvesting. Using this technique the fluid is for cedinto another reservoir by using the osmosis effect, temperature gradient and pressure exerted to produce energy. In this study, we using the osmosis effect enhance by the temperature gradient to study the dynamics of fluid across the membranes for heat
harvesting energy with different porosity. The materials that have been used to create the membranes are polyvinylidene fluoride (PYDF) because it has high thermal resistivity, high chemical resistance and good mechanical properties. Electrospinning machine was used to create the membranes with different porosity needed. The previous study show electrospinning machine will creates a beta
phase of PVDF electro spun. From the experiment, sample of 10V
shows higher efficiency in the dynamic of fluid pass through the
membrane which is 0.009 m3 change in volume with 1.9485x10-5 N
of the osmotic pressure. This is because the formation of beads a less
compared to 14V and 18V where beads almost in every topology of
membranes. The formation of fibers in the samples of 10Y, 14V and
18Y are well distributed by using electrospinning machine and we
can see the porosity increased as the voltage increase.
