Abstract

Bio–nanocomposite compounds based on biopolymers and MOFs have presented great potential in various applications for modern technology.

Abstract

Currently, due to economic importance and environmental characteristics, biopolymeric matrices containing metal–organic frameworks (MOFs) are being extraordinarily considered in high-tech and commercial applications. In these materials, MOFs are usually incorporated into polymer chains and highly effective and multi-functional organic–inorganic composites are fabricated with high electrical, optical, mechanical, and thermal features. The excellent porous structure, flexibility, and organic–inorganic nature of MOFs are interesting properties for their examination in the fabrication of biopolymeric composites. Here, we provide a complete and vital review of MOF/biopolymeric composites in recent years and discuss their importance and features. Additionally, since bio–nanocomposite materials based on biodegradable polymers and MOFs have presented great potential in the past decade, in this review, we have critically concentrated on the most significant and interesting applications of MOF/biopolymeric composites and their advantages in modern technology.

Metal-organic framework nanosheets in polymer composite materials for gas separation

Tania Rodenas, Ignacio Luz, Gonzalo Prieto … (2015)

Composites incorporating two-dimensional nanostructures within polymeric matrices hold potential as functional components for several technologies, including gas separation. Prospectively, employing metal-organic-frameworks (MOFs) as versatile nanofillers would notably broaden the scope of functionalities. However, synthesizing MOFs in the form of free standing nanosheets has proven challenging. We present a bottom-up synthesis strategy for dispersible copper 1,4-benzenedicarboxylate MOF lamellae of micrometer lateral dimensions and nanometer thickness. Incorporating MOF nanosheets into polymer matrices endows the resultant composites with outstanding CO2 separation performance from CO2/CH4 gas mixtures, together with an unusual and highly desired increment in the separation selectivity with pressure. As revealed by tomographic focused-ion-beam scanning-electron-microscopy, the unique separation behaviour stems from a superior occupation of the membrane cross-section by the MOF nanosheets as compared to isotropic crystals, which improves the efficiency of molecular discrimination and eliminates unselective permeation pathways. This approach opens the door to ultrathin MOF-polymer composites for various applications.
