Abstract

Penelitian ini mengembangkan membran Mixed Matrix Membrane (MMM) berbasis P84 ko-poliimida dengan filler CuO@AK-Zeolit-Y (CuO@AKZY) untuk aplikasi pemisahan gas CO₂/CH₄. Polimer P84 ko-poliimida dipilih karena selektivitas gasnya yang tinggi, namun sifat mekaniknya perlu ditingkatkan melalui variasi suhu fabrikasi. Filler CuO@AK-Zeolit-Y disintesis dengan variasi loading Cu sebesar 15, 20, 25, dan 30%. Membran neat difabrikasi pada suhu 35, 50, dan 65°C, sedangkan seluruh membran MMM difabrikasi pada suhu 35°C dengan komposisi filler sebesar 1,5% b/b. Karakterisasi dilakukan menggunakan X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy–Energy Dispersive X-Ray (SEM-EDX), Brunauer–Emmett–Teller (BET) surface area analysis, serta uji kinerja adsorpsi gas. Hasil karakterisasi XRD dan FTIR menunjukkan bahwa membran Neat-35°C memiliki struktur yang lebih amorf dan permeabel dibandingkan Neat-50°C akibat terjadinya thermally induced relaxation. Uji adsorpsi menunjukkan bahwa filler dengan penambahan 20% Cu memiliki kapasitas adsorpsi tertinggi dan dispersi Cu yang merata. Material ini memiliki luas permukaan BET sebesar 386,58 m²/g. Namun, kinerja pemisahan gas terbaik diperoleh pada membran MMM dengan penambahan Cu 25%, yang menunjukkan selektivitas H2/CO2 sebesar 3,25 dan 1,53 untuk CH4/CO2. Hasil ini menunjukkan bahwa kombinasi rasio Cu yang tepat dan pengaturan suhu fabrikasi dapat meningkatkan efisiensi dan stabilitas membran untuk aplikasi pemisahan gas.

=This study developed a Mixed Matrix Membrane (MMM) based on P84 co-polyimide with CuO@AK-Zeolite-Y (CuO@AKZY) filler for CO₂/CH₄ gas separation applications. P84 co-polyimide polymer was chosen due to its high gas selectivity, but its mechanical properties need to be improved through variations in fabrication temperature. CuO@AK-Zeolite-Y filler was synthesized with variations in Cu addition of 15, 20, 25, and 30%. The pure membrane was fabricated at 35, 50, and 65°C, while all MMM membranes were fabricated at 35°C with a filler composition of 1.5% w/w. Characterization was performed using X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy–Energy Dispersion X-ray (SEM-EDX), Brunauer–Emmett–Teller (BET) surface area analysis, and gas adsorption performance tests. The XRD and FTIR characterization results showed that the Neat-35°C membrane had a more amorphous and permeable structure than the Neat-50°C membrane due to thermally induced relaxation. The adsorption test showed that the filler with 20% Cu addition had the highest adsorption capacity and uniform Cu dispersion. This material had a BET surface area of 386.58 m²/g. However, the best gas separation performance was obtained in the MMM membrane with 25% Cu addition, which showed a selectivity of 3.25 for H2/CO2 and 1.53 for CH4/CO2. These results indicate that the combination of appropriate Cu ratio and fabrication temperature settings can improve the efficiency and stability of the membrane for gas separation applications.
