Synthesis and Characterization of Chitosan/Phosphotungstic Acid-Montmorillonite Modified by Silane for DMFC Membrane

Abstract: Montmorillonite was functionalized by (3-glycidyloxypropyl) trimethoxy silane (GPTMS). Subsequently, chitosan (CS) membranes filled by GPTMS-modified

“…Lupatini et al reported a conductivity of 1.9 × 10 –2 S cm –1 at 100% relative humidity and 80 °C by cross-linking chitosan with sulfuric acid . Several other chitosan composites have been reported as polymer electrolytes, such as chitosan and polysulfone, sulfonated polysulfone, phosphotungstic acid, , phosphomolybdic acid, zeolites, sulfonated graphene oxide, and silicotungstic acid. , Finally, Alves and co-workers linked the individual properties of chitosan, such as deacetylation and molar mass, to the proton conductivity of the resulting membrane. They concluded that lower deacetylation and higher molar mass were favorable, with different thicknesses resulting in an order of magnitude increase in proton conductivity …”

“…Jumlah kitosan yang lebih banyak menyebabkan membran lebih banyak menyerap air (hidrofilik), mengurangi permeabilitas metanol dan meningkatkan nilai IEC. Penelitian lain yang dilakukan oleh (Permana et al, 2015) menunjukkan bahwa membran DMFC yang terbuat dari kitosan/asam fosfotungstat-montmorrilonite yang dimodifikasi dengan silan memiliki permeabilitas metanol yang lebih rendah. Hal tersebut menandakan bahwa kitosan merupakan kandidat yang potensial sebagai membran DMFC.…”

“…Penggunaan konsentrasi HCl dan suhu reaksi harus diperhatikan karena kitin dapat mencair apabila menggunakan asam dengan konsentrasi terlalu tinggi dan pada temperature yang tinggi HCl dapat mengakibatkan senyawa kitin terdegradasi (Permana, 2015).…”
