“…These membranes' nanofibril diameter, mean pore size and specific area are shown in Table 10. 648 The incorporation of inorganic nanoparticles, such as Pd, 626 TiO 2 , 628 GO, 625 MoS 2 , and SiO 2 , 629 in the BC membrane could enhance the separation performance of the composite membrane, which would simultaneously adsorb and photocatalytically reduce the impurities by light irradiation. For example, a BC membrane cross-linked with polydopamine (PDA), BC/PDA, exhibited good filtration capability to remove R6G, MB and MO dyes.…”

Nanocelluloses (NC) are nature-based sustainable biomaterials, which not only possess cellulosic properties but also have the important hallmarks of nanomaterials, such as large surface area, versatile reactive sites or functionalities, and scaffolding stability to host inorganic nanoparticles. This class of nanomaterials offers new opportunities for a broad spectrum of applications for clean water production that were once thought impractical. This Review covers substantial discussions based on evaluative judgments of the recent literature and technical advancements in the fields of coagulation/flocculation, adsorption, photocatalysis, and membrane filtration for water decontamination through proper understanding of fundamental knowledge of NC, such as purity, crystallinity, surface chemistry and charge, suspension rheology, morphology, mechanical properties, and film stability. To supplement these, discussions on low-cost and scalable NC extraction, new characterizations including solution small-angle X-ray scattering evaluation, and structure− property relationships of NC are also reviewed. Identifying knowledge gaps and drawing perspectives could generate guidance to overcome uncertainties associated with the adaptation of NC-enabled water purification technologies. Furthermore, the topics of simultaneous removal of multipollutants disposal and proper handling of post/spent NC are discussed. We believe NC-enabled remediation nanomaterials can be integrated into a broad range of water treatments, greatly improving the cost-effectiveness and sustainability of water purification.

“…The BC-coated polyethyleneimine membranes synthesized by a flush-coating and post-cross-linking method presented potent adsorption for copper and lead ions from aqueous solutions [137]. However, a novel membrane-based on BCNF with polydopamine particles and palladium nanoparticles has demonstrated success in the removal of cationic, anionic, and neutral pH dye (3-9) (99%) [138]. In an attempt to remove mercury from wastewater, Tamahkar et al [139] synthesized modified bacterial cellulose nanofibers by using Cibacron Blue F3GA.…”

Cellulose is among the world's wealthiest biopolymers and primarily has a wood, plant, and microbial source. To date, cellulose nanofibers (CNFs) are synthesized under controlled conditions (temperature, pH, and agitation). The bacterial synthesis of CNFs, so-called bacterial cellulose (BC), has become actively interested in recent times. These emerged natural biopolymers have excellent hydrophilicity, biodegradability, renewability, and mechanical properties. The nanoscale dimension of the synthesized cellulose provides a sizeable functional surface area, low weight and density, and a high-interconnected pore system. Based on these properties, bacterial cellulose nanofibers open a broad range of environmental applications as biosorbents, ultrafiltration membrane, as well as a bio-reducing agent for the biosynthesis of nanoparticles with high photocatalytic activity. Moreover, these nanofibers prove their complete applications in the biomedical, textile, food, and cosmetic industries. The present chapter is devoted to investigating the mechanism of bacterial cellulose nanofibers biosynthesis, functionalization, and its area of applications.

“…For example, mixing the triblock copolymer PEO-PPO (poly-phenyleneoxide)-PEO, which contains moieties that can interact with both organic and inorganic components, into PES UF membrane can improve the interfacial compatibility with TiO 2 NPs [198]. As other additives, PDA (polydopamine) has been exclusively researched [198][199][200]. In this strategy, many polymers with moieties which can interact with both polymeric and ceramic components, can be good candidates as the additives.…”

Clean water supply is an essential element for the entire sustainable human society, and the economic and technology development. Membrane filtration for water and wastewater treatments is the premier choice due to its high energy efficiency and effectiveness, where the separation is performed by passing water molecules through purposely tuned pores of membranes selectively without phase change and additional chemicals. Ceramics and polymers are two main candidate materials for membranes, where the majority has been made of polymeric materials, due to the low cost, easy processing, and tunability in pore configurations. In contrast, ceramic membranes have much better performance, extra-long service life, mechanical robustness, and high thermal and chemical stabilities, and they have also been applied in gas, petrochemical, food-beverage, and pharmaceutical industries, where most of polymeric membranes cannot perform properly. However, one of the main drawbacks of ceramic membranes is the high manufacturing cost, which is about three to five times higher than that of common polymeric types. To fill the large gap between the competing ceramic and polymeric membranes, one apparent solution is to develop a ceramic-polymer composite type. Indeed, the properly engineered ceramic-polymer composite membranes are able to integrate the advantages of both ceramic and polymeric materials together, providing improvement in membrane performance for efficient separation, raised life span and additional functionalities. In this overview, we first thoroughly examine three types of ceramic-polymer composite membranes, (i) ceramics in polymer membranes (nanocomposite membranes), (ii) thin film nanocomposite (TFN) membranes, and (iii) ceramic-supported polymer membranes. In the past decade, great progress has been made in improving the compatibility between ceramics and polymers, while the synergy between them has been among the main pursuits, especially in the development of the high performing nanocomposite membranes for water and wastewater treatment at lowered manufacturing cost. By looking into strategies to improve the compatibility among ceramic and polymeric components, we will conclude with briefing on the perspectives and challenges for the future development of the composite membranes.
