Abstract

CO2 yang dipancarkan ke lingkungan yang dapat mengakibatkan peningkatan jumlah gas rumah kaca (GRK) dapat dikurangi lebih lanjut dengan menggunakan direct air capture (DAC), yang merupakan metode pengurangan CO2 dalam program CCUS. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh variabel komponen matriks polimer PAN terhadap membran dalam hal sifat termal dan sifat mekaniknya, sementara juga memperhatikan morfologi nanofiber itu sendiri. Proses pembuatan membran nanofiber PAN/CsPbBr3, dimulai dengan mensintesis larutan perovskit CsPbBr3. Setelah itu, sintesis polimer PAN dilakukan, diakhiri dengan mencampur bahan keramik perovskit dan polimer PAN bersama-sama dan mulai mencampurnya. Proses pembuatan membran PAN/CsPbBr3 memerlukan pemanfaatan electrospinning, karena kami ingin mencapai produk akhir dari membran/nanofiber yang halus. Dengan fokus utama pada analisis sifat mekanik dan analisis resistansi termal, penelitian ini memerlukan beberapa prosedur pengujian seperti: Pemetaan SEM/EDX, DTA/TGA, dan FTIR. Dalam penelitian ini kami juga memecah resistansi termal berdasarkan data dari DTA/TGA, di mana kami mengambil rata-rata dari setiap puncak suhu yang ditunjukkan pada data. Karena penelitian difokuskan juga untuk memasukkan pengujian mekanis dari uji tarik ultimit, dapat diperoleh perpanjangan tercatat sebesar 26,18% untuk membran nanofiber PAN saja, yang seperti yang diharapkan bahwa sebelum perlakuan panas, membran nanofiber PAN dan PAN/CsPbBr3 akan lebih ulet. Pengujian mekanis juga dilakukan dengan perlakuan panas yang diterapkan pada membran nanofiber, dan itu menunjukkan bahwa perpanjangan pada membran nanofiber PAN saja hanya 21,77. Oleh karena itu dapat disimpulkan bahwa nanofiber lebih getas dibandingkan dengan yang sebelum perlakuan panas. Suhu termal yang ditetapkan untuk penelitian membran nanofiber PAN/CsPbBr3 ini adalah 250°C – 260°C, sebelum nanofiber mengalami kerusakan. Hal ini diharapkan agar material komposit nanofiber ini memiliki toleransi termal yang lebih tinggi dibandingkan dengan nanofiber lain yang terbuat dari material komposit film lainnya.

CO2 emitted in to the environment that can results in the increase amount of green house gases (GHG) can be further mitigated by using direct air capture (DAC), which is a method of CO2 reduction in CCUS program. The purpose of this research is to analyze the effect of PAN polymer matrix component variable towards the membrane in term of their thermal properties and mechanical properties, while also concerning about the morphologies of the nanofiber itself. The process of manufactured the PAN/CsPbBr3 nanofiber membrane, starts by synthesizing the CsPbBr3 perovskite solution. Afterwards the synthesizing of the polymer PAN is conducted, finished by mixing bothh the perovskite ceramic materials and the PAN polymer together and start mixing it. The manufacturing process of PAN/CsPbBr3 membrane required the utilization of electrospinning, because we wanted to achieve the final product of a fine membrane/nanofiber. With the main focus of mehcanical properties analysis and thermal resistance analysis, this research required several testing procedure such as : SEM/EDX Mapping, DTA/TGA, and FTIR. In this research we also breakdown the thermal resistance based on the data from DTA/TGA, where we took the average from each temperature peak shown on the data. Because of the research focused in also including the mechanical testing of ultimate tensile test, it can be obtained the elongation is recorded at 26.18 % for the PAN only nanofiber membrane, which is as expected that in before heat tretamnet the PAN and PAN/CsPbBr3 nanofiber membrane would be more ductile. Mechanical testing are also conducted with heat treatment applied to the to the nanofiber membrane, and it shows that the elongation in PAN only nanofiber membrane was only 21.77. Therefore it can be conclude that the nanofiber was more brittle compare to the one in before heat treatment. The thermal temperature set for this research of PAN/CsPbBr3 nanofiber membrane are set to 250oC – 260oC, before the nanofiber gets deteriorate. This was expected for this composite materials nanofiber to have a higher thermal tolerance compare to other nanfiber made from other film composite materials.
