文摘

Flexible crystalline metal鈥搊rganic framework (MOF) of nanosize particles (Al-MIL-53) and 6FDA-ODA polyimides were used to produce mixed matrix membranes (MMM). These MMM display excellent CO₂/CH₄ separation properties even without any compatibilization (amine grafting). The ideal selectivity and separation factor were found to increase with increasing MOF loading. Furthermore, these materials have an improved CO₂/CH₄ separation factor with increasing pressure, in contrast to traditional polymer membranes.
