“…It can increase the hydrophilicity of other material surfaces due to the hydrophilic properties of PDA. 21 Recently, polydopamine has been reported to increase the dispersion of MOFs by simply stirring 22 due to because polydopamine increases the hydrophilicity of MOFs. Therefore, increasing the dispersion of MOFs by PDA is not only a feasible but also a simpler and high-efficient strategy compared with other methods such as adjusting particle size.…”

Metal-organic frameworks (MOFs) are porous crystal frameworks constructed by metal clusters and bridging organic ligands. [1] This class of materials not only has a highly tunable and regular pore structure, variable functionality, and internal connectivity, [2] but the superior designability enables them to accommodate the introduction of a variety of functional sites on frames, cavities, and channels. [3] These make them have important applications in many fields, including drug delivery, [4] adsorption, [5] antimicrobials, [6] electron conduction, [7] gas storage, [8] catalysis, [9] sensing, [10] and energy conversion. [11] MOFs were first developed by Hoskins and Robson via connecting discrete metal clusters and reappraising the Zn(CN) 2 and Cd(CN) 2 structure [12] and then termed MOFs in 1995. [13] Recent researches focus on the modulation of MOF chemistry to expending our understanding of the relationship between the MOFs structure, function, and applications. However, the poor adhesion and heterogeneous distribution of powdery MOFs hindered their detection in many applications. So, the development of the commercialization of MOFs was limited. [14] Membrane is a kind of material with small pore size and large specific surface area. [15] A series of structural features facilitate its rapid transfer of matters with the action of external driving forces in the field of biomedical, [16] energy storage, [17] and environmental protection. [18] The preparation of MOFs into membranes will play their role to the maximum extent [14,19] and endow more precisely pore size, pore structure, and molecular-/ion-specific groups with the membranes. [20] MOF membranes are mainly divided into two categories: pure MOF membranes and MOF/polymer hybrid membranes. Pure MOF membranes are the continuous thin layers of MOFs that are formed by growing (or depositing) on a porous support layer and/or inorganic substrate or a porous polymer substrate. These kinds of MOF membranes have the advantages of good thermal stability, high mechanical property, antifouling, antiswelling, and controllable pore structure. [21] As pure MOF membranes are composed of MOFs, the permeability and selectivity are completely determined by the pore sizes of MOFs, which endow pure MOF membranes with significant selectivity. [22] Pure MOF membranes should have the best performance in theory. However, their brittle texture, high cost, and difficulty in chemical modification still limit their practical applications. MOF/polymer hybrid membranes are composite materials that are composed of a dispersed phase (MOFs) and a continuous phase (polymer or another flexible matrix). There are two forms: MOFs embedded in the polymer matrix and MOFs on the surface of the flexible substrate. The thickness is much thicker than the diameter of the embedded porous MOFs; thus, the doped MOFs are surrounded by the polymer matrix. In this case, the selectivity and permeability of the MOF/polymer hybrid membranes are significantly dependent on the properties of the

“…Meanwhile, introducing modified NPs by PDA into the PA selective layer has made the crumpled structure of the TFC membrane smoother as well as the tufts become shorter and narrower [ 48 ]. A modified hydrophilic zeolitic imidazolate framework-8 (ZIF-8) nanoparticles by polydopamine modification were highly dispersed in a well-mixed aqueous solution containing 2 wt% piperazine (PIP), 2 wt% triethylamine (TEA), 4.6 wt% camphorsulfonic acid (2CSA), and 0.01 wt% PDA-ZIF-8 nanoparticles for enhancing PA layer formation onto PSf membrane surface [ 59 ]. The TFN membrane that resulted in a negatively charged surface has increased water permeability without sacrificing selectivity and ensured that multivalent anions and dyes were effectively rejected [ 59 ].…”

Incorporating polydopamine has become a viable method for membrane modification due to its universality and versatility. Fillers in their different categories have been confirmed as effective elements to improve the properties of membranes such as hydrophilicity, permeability, mechanical strength, and fouling resistance. Thus, this paper mainly highlights the recent studies that have been carried out using polydopamine and nanomaterial fillers simultaneously in modifying the performance of different membranes such as ultrafiltration, microfiltration, nanofiltration, reverse osmosis, and forward osmosis membranes according to the various modification methods. Graphene oxide nanoparticles have recently attracted a lot of attention among different nanoparticles used with polydopamine, due to their impressive characteristics impacts on enhancing membrane hydrophilicity, mechanical strength, and fouling resistance. Thus, the incorporation techniques of graphene oxide nanoparticles and polydopamine for enhancing membranes have been highlighted in this work. Moreover, different studies carried out on using polydopamine as a nanofiller for optimizing membrane performance have been discussed. Finally, perspectives, and possible paths of further research on mussel-inspired polydopamine and nanoparticles co-incorporation are stated according to the progress made in this field. It is anticipated that this review would provide benefits for the scientific community in designing a new generation of polymeric membranes for the treatment of different feed water and wastewater based on adhesive mussel inspired polydopamine polymer and nanomaterials combinations.
