“…The nanomaterials have also been explored recently to modify the surface properties of synthetic membranes. Different types of nanomaterials, such as SiO 2 , 35 TiO 2 , 36 ZrO 2 37 , 38 ( Figure 3 ), carbon nanotubes (CNT), 39 and graphene oxide (GO), 40 have been used as additives to different polymeric materials, such as cellulose acetate (CAc), PVDF, PA, PEI, and sulfone polymer, to achieve the desired functional properties. 41 Among inorganic nanomaterials, GO is one of the most appealing nanomaterials because of the presence of hydroxyl, epoxy, carbonyl, and carboxyl reactive species that provide high solubility in polar solvent with good colloidal properties, low toxicity, and a large surface area which can be useful for further modification.…”

Membrane technology is playing a crucial role in cutting-edge innovations in the biomedical field. One such innovation is the surface engineering of a membrane for enhanced longevity, efficient separation, and better throughput. Hence, surface engineering is widely used while developing membranes for its use in bioartificial organ development, separation processes, extracorporeal devices, etc. Chemical-based surface modifications are usually performed by functional group/biomolecule grafting, surface moiety modification, and altercation of hydrophilic and hydrophobic properties. Further, creation of micro/nanogrooves, pillars, channel networks, and other topologies is achieved to modify physio-mechanical processes. These surface modifications facilitate improved cellular attachment, directional migration, and communication among the neighboring cells and enhanced diffusional transport of nutrients, gases, and waste across the membrane. These modifications, apart from improving functional efficiency, also help in overcoming fouling issues, biofilm formation, and infection incidences. Multiple strategies are adopted, like lysozyme enzymatic action, topographical modifications, nanomaterial coating, and antibiotic/antibacterial agent doping in the membrane to counter the challenges of biofilm formation, fouling challenges, and microbial invasion. Therefore, in the current review, we have comprehensibly discussed different types of membranes, their fabrication and surface modifications, antifouling/ antibacterial strategies, and their applications in bioengineering. Thus, this review would benefit bioengineers and membrane scientists who aim to improve membranes for applications in tissue engineering, bioseparation, extra corporeal membrane devices, wound healing, and others.

“…Schematic illustration of the GO-PDI-modified α-Al 2 O 3 composite membrane preparation (Feng et al, 2016). Saf et al (Saf et al, 2015) synthesized a novel reduced graphene oxide/polythiophene (rGO/PTh) membrane employing in-situpolymerization as a simple and green synthesis method and incorporated it into polysulfone (PSF) via a phase inversion approach. The developed graphene membrane exhibited a microporous sponge-like structure, high porosity, and good hydrophilicity due to the addition of rGO/PTh nanocomposite.…”

Currently, as the population continues to grow, the preservation of the world’s water resources is becoming a serious challenge. The seawater desalination process is considered a sustainable option for the future. The two most common technologies used in desalination are reverse osmosis (RO) and membrane distillation (MD). However, membrane fouling caused by the accumulation of contaminants membrane surface is an emerging and growing problem. then a pre-treatment stage is required to reach an optimal efficiency during desalination process, since this stage is crucial for a successful desalination process. In this regard, developing new material-based composite membranes has the potential to upgrade the anti-fouling features of RO membranes and thereby enhance the desalination efficiency due to the characteristics of these composite membranes especially, their high permeability, hydrophilicity, selectivity mechanical strength, thermal stability, and anti-bacterial property. The objective of this review is to present the main techniques for seawater pre-treatment. the results of several membrane types and methods of modification were also discussed. Finally, the performance of composite membranes for seawater pre-treatment is defined and future perspectives are highlighted.

“…Additions of Fe 2 O 3 enhanced the membrane hydrophilicity but an increase in Fe 2 O 3 content caused a notable drop in the surface porosity of membrane. Furthermore, rejection studies were performed in (154). Inclusion of rGO/ PTh hybrid filler increased permeability and protein rejection.…”

“…Inclusion of rGO/ PTh hybrid filler increased permeability and protein rejection. In this MMM, rGO added porosity to the membrane surface, while PTh enhanced hydrophilicity even though rGO alone is hydrophobic (154). A research by Teli et al demonstrated that MMMs containing hybrid fillers polyaniline (PANI)/phosphomolybdicacid (PMA) in PES offered a better antifouling activity and more efficient membranes than the simple PES membrane (155).…”

Membrane technology has been utilized for water purification application for a long time. Both polymeric and ceramic membranes have been center of interest for their tremendous contribution in this area. Despite their advantages, these synthetic membranes have limitations in terms of performance and durability. To meet the new demands and standards, mixed matrix membranes (MMM) have gained serious importance due to their ability to combine the features of the aforementioned membrane materials, offering better solutions in terms of performance, fouling, permeate quality and longevity. Besides such attractive features, MMMs have not yet reached sufficient maturity to challenge conventional membranes commercially. This review categorizes MMMs on its filler basis into four types; (i) inorganic filler-based MMMs, (ii) organic filler-based MMMs, (iii) biofillers-based MMMd, and (iv) hybrid filler-based MMMs. A discussion is extended to modules and cost of these membranes along with the specific applications of each type of fillers. It also identifies the issues and challenges in the MMM area and highlights the domains that remain to be investigated.
