Abstract In this research, the effect of adding MIL-100 (Fe) MOFs on the PEBAX membranes has been scrutinized in two grades of 1657 and 2533. Initially, the intended membranes were synthesized by the solution-casting method. Then, the XRD and SEM were applied to deliberate the influence of adding MIL-100 (Fe) to the structure of both types of membranes. In consequence, the separation function of the pair gases of CO2/CH4، CO2/N2 and CO2/O2 and their permeability were considered at the pressure of 3.5 bar and temperature of 25°C. Eventually, their function was compared by Robeson diagrams of 1991 and 2008. The comparison results by Robeson diagrams indicated that the PEBAX1657/MIL-100 (Fe) and PEBAX2533/MIL-100 (Fe) membranes containing 5 wt.% of MOF represent more suitable performance in separating CO2/CH4 in comparison with the axis of the Robeson diagram. However, their function for separating the aforementioned gases requires more modifications.

Teknologi pemisahan gas telah banyak dilakukan menggunakan membran. Mixed matrix membran (MMMs) telah banyak dikembangkan dengan mengkombinasikan polimer organik dan filler anorganik. Pemisahan gas dengan mixed matrix membrane telah banyak dikembangkan dan menghasilkan kinerja yang sangat baik. Pada pemisahan gas CO 2 /CH 4, satu hal yang diutamakan dan diperhatikan adalah permeabilitas yang tinggi. Umumnya semakin tinggi permeabilitas suatu gas dalam membran, maka semakin rendah pula selektivitasnya dan begitu pula sebaliknya. Beberapa filler yang baik digunakan untuk mixed matrix membrane yaitu dengan filler material silika, nanopartikel NiO, grafena oksida dan metal organic frameworks (MOF).Kata Kunci: Mixed matrix membrane, pemisahan gas

Stereocomplexation is one of several approaches for improving polylactide (PLA) properties. The high molecular weight of poly L-lactide (PLLA) and poly D-lactide (PDLA) homopolymers are a constraint during the formation of stereocomplex PLAs (s-PLAs). The presence of s-PLA particles in PLA PLLA/PDLA blends can initiate the formation of s-PLA crystalline structures. We used the solution casting method to study the utilization of s-PLA materials from high molecular weight PLLA/PDLA blends for increasing s-PLA formation. The s-PLA particles initiated the formation of high molecular weight PLLA/PDLA blends, obtaining 49.13% s-PLA and 44.34% of the total crystalline fraction. In addition, the mechanical properties were enhanced through s-PLA crystalline formation and the increasing of total crystallinity of the PLLA/PDLA blends. The s-PLA particles supported initiation for s-PLA formation and acted as a nucleating agent for PLA homopolymers. These unique characteristics of s-PLA particles show potential to overcome the molecular weight limitation for stereocomplexation of PLLA/PDLA blends.
