Abstract
Penelitian ini bertujuan membuat bahan separator komposit
poli(vinilidene flouride) (PVDF) dan poli(dimetilsiloksan) (PDMS)
dengan metode pencampuran membran (blending membrane).
Perbandingan variasi komposisi PVDF/PDMS yaitu 10:0, 9:1, 8:2, dan
7:3. Tujuan dari peningkatan fraksi konsentrasi dari PDMS terhadap
PVDF untuk meningkatkan performa separator komposit yang meliputi
dimensi porositas, kerapatan pori, dan konduktivitas listriknya.
Berdasarkan analisa kristalografi dengan menggunakan XRD,
peningkatan konsentrasi PDMS mengakibatkan menurunnya derajat
kristalinitas yaitu sebesar 29,26% pada perbandingan 7:3 dan
berdasarkan interpretasi data FTIR material tersebut termasuk kedalam
kriteria bahan komposit karena kedua fasa dari bahan masih bisa
dibedakan bilangan gelombang vibrasi molekuler masing-masing bahan
penyusunnya. Hasil analisa XRD fasa kristalin PVDF termasuk kriteria
jenis fasa α-PVDF. Semakin tinggi konsentrasi PDMS mengakibatkan
penurunan dimensi porositas dan meningkatkan kerapatan
porositasnya, dengan dimensi pori terkecil sebesar 1,71 µm dan
kerapatan pori sebesar 4,07x10

pada perbandingan 7:3.
Pada perbandingan komposisi 7:3 mempunyai nilai konduktivitas listrik
sebesar 3,45 x 10

S/cm dan resistansi meningkat hingga 80% pada
penambahan PDMS. Berdasarkan kriteria diatas, material ini dapat
dikategorikan sebagai bahan separator pada baterai ion lithium

This research aims to create a composite poly(vinylidene fluoride)
(PVDF) and poly (dimetilsiloksan) (PDMS) separator with blending
membrane method. Ratio of composition of PVDF/PDMS were 10:0,
9:1, 8:2, and 7:3. The purpose of increasing concentration of PDMS to
PVDF to improve the performance of the composite separator which
includes the dimensions of porosity, pore density, and electrical
conductivity. Based on crystallographic analysis using XRD, the
adoption concentration of PDMS resulted in a decreased crystallinity
reached 29.26% in the ratio 7:3 and based on FTIR data, the material
includes in the criteria composite material because both phase of the
material can still be distinguished molecular vibrational wavenumber
respectively their constituent materials. The results of XRD analysis
PVDF crystalline phases was α-PVDF type. The adoption
concentration of PDMS not only decreases pore dimensions but also
increases the pore density, with the smallest pore dimensions was 1.71
µm and pore density was 4.07 x1011 count/m

in
the ratio 7:3. In the
ratio of composition 7:3, the value of the electrical conductivity was
3.45x10

S/cm and the resistance increases up to 80% on the adoption
of PDMS. Based on the above criteria, this material can be categorized
as a separator material in lithium ion batteries
