ABSTRAK

Penelitian ini bertujuan membuat bahan separator komposit polivinilidene flouride PVDF dan polidimetilsiloksan PDMS dengan metode pencampuran membran blending membrane. Perbandingan variasi komposisi PVDFPDMS yaitu 100 91 82 dan 73. 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 2926 pada perbandingan 73 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 945-PVDF. Semakin tinggi konsentrasi PDMS mengakibatkan penurunan dimensi porositas dan meningkatkan kerapatan porositasnya dengan dimensi pori terkecil sebesar 171 956m dan kerapatan pori sebesar 407x1011 countm2 pada perbandingan 73. Pada perbandingan komposisi 73 mempunyai nilai konduktivitas listrik sebesar 345 x 10-4 Scm dan resistansi meningkat hingga 80 pada penambahan PDMS. Berdasarkan kriteria diatas material ini dapat dikategorikan sebagai bahan separator pada baterai ion lithium.


ABSTRACT

This research aims to create a composite polyvinylidene fluoride PVDF and poly dimetilsiloksan PDMS separator with blending membrane method. Ratio of composition of PVDFPDMS were 100 91 82 and 73. 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 73 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 945-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 956m and pore density was 4.07 x1011 countm2 in the ratio 73. In the ratio of composition 73 the value of the electrical conductivity was 3.45x10-4 Scm 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.
