Synthesis and characterization of metal-organic framework and carbon nanotubes in mixed matrix membrane

Synthesis and characterization of metal-organic framework and carbon nanotubes in mixed matrix membrane / Asrin Haikal Amir Hamzah
Organik besi kerangka (MOF) dan organic besi kerangka bersama Karbon Nanotube berdinding multi (MWCNT) sudah disintesiskan dengan menggunakan kaedah solvothermal. MWCNT-MOF adalah antara bahan yang sangat menarik kerana mempunyai pelbagai kelebihan yang berpotensi tinggi dalam banyak aplikasi. Sampel yang diperoleh dari kaedah solvothermal digunakana di mikroscop electron pengimbasan (SEM), Brumair-Emmet-Teller (BET) dan proses pervaporasi. Prestasi proses pervaporasi MWCNT/PVA/PVDF dan MOF/PVA/PVDF menunjukkan fluks dan kandungan air yang lebih tinggi.. Fluks untuk MWCNT-MOF/PVA/PVDF didapati lebih tinggi apabila dibandingkan dengan MOF/PVA/PVDF di mana fluks MWCNT-MOF/PVA/PVDF ialah 0.00217 g/cm2.h dan MOF/PVA/PVDF ialah 0.00178 g/cm2.h. Selain itu, kandungan air MWCNT-MOF/PVA/PVDF didapati lebih tinggi apabila dibandingkan dengan MOF/PVA/PVDF iaitu 48.4306% dan 34.8093% masing-masing. Penambahbaikan dipercayai disebabkan oleh pengurangan penambahan luas permukaan dan sifat hydrophilic oleh organic besi kerangka (MOF) dan Karbon Nanotube berdinding multi (MWCNT). _______________________________________________________________________________________________________ Metal organic frameworks (MOFs) and MOFs incorporated with multi-walled carbon nanotubes (MWCNTs) (MWCNT-MOF) were successfully synthesized by using solvothermal method. The MWCNT-MOF is a very interesting material due to their various potential applications. The samples were characterized by using scanning electron microscopy (SEM), Brumair-Emmet-Teller (BET) and pervaporation process. The pervaporation performances of the MWCNT-MOF/PVA/PVDF and MOF/PVA/PVDF exhibited higher in terms of flux and water content. The flux for the MWCNT-MOF/PVA/PVDF was observed to be higher as compared MOF/PVA/PVDF which were 0.00217 g/cm2.h and 0.00178 g/cm2.h, respectively. Besides that, the water content of the MWCNT-MOF/PVA/PVDF was observed to be higher as compared to the MOF/PVA/PVDF which are 48.4306% and 34.8093% respectively. The improved performances are believed to be due to the increased of the surface area and hydrophilicity of the MOF and MWCNTs.
