CHARACTERIZATION OF PROPERTIES OF PVDF/POLY(DIMETHYLSILOXANE) COMPOSITES SEPARATOR WITH BLENDING MEMBRANE METHOD

<span lang="IN">The aims of this research to make</span><span> poly(vinylidene fluoride) (PVDF) and poly(dimetilsiloksan) (PDMS) </span><span lang="IN">composites </span><span>separator with blending membrane method. </span><span lang="IN">Synthesized of<span> </span></span><span>PVDF/PDMS</span><span lang="IN"> composites separator </span><span lang="IN">used various ratio </span><span>were 10/0, 9/1, 8/2, and 7/3. The purpose of increasing concentration of PDMS</span><span lang="IN">/</span><span>PVDF to improve the performance of the composites separator which includes </span><span lang="IN">a</span><span> dimensions of porosity, </span><span lang="IN">a </span><span>pore density, and </span><span lang="IN">a </span><span>electrical conductivity.

The result using XRD and FTIR to material PVDF/PDMS composites in all of the ratio constituens have shown the identification of the structure </span><span>α-</span><span lang="IN">phase of PVDF. The increase of concentration number PDMS influenced decreasing of pore dimension and increasing of pore density </span><span>with the small </span><span lang="IN">of </span><span>pore dimension 1.71 µm and pore density 4.07x10¹¹ count/m²inthe ratio 7/3. In </span><span lang="IN">a</span><span> ratio 7/3, the value of the electrical conductivity w</span><span lang="IN">as </span><span>3.45x10^-4</span><span>S/cm and the resistance </span><span lang="IN">i</span><span>ncrease</span><span lang="IN">d</span><span> up to 80%.</span>
