“…11 Therefore, various methods to improve the antifouling properties of PES membranes have been studied by researchers. For example, studies on interfacial polymerization, 12,13 surface graft polymerization, 14 ultraviolet irradiation, 15 coating, 16 and blending 5,17,18 have been carried out with different membrane modifiers. The blending of inorganic materials into membranes as modifiers has been one focus area of this research.…”

Zn-Al layered double hydroxide (LDH)-entrapped poly(ether sulfone) (PES) ultrafiltration membranes with four different weight percentages, 0.5, 1.0, 2.0, and 3.0%, were prepared by a phase-inversion method. Characterization by scanning electron microscopy, atomic force microscopy and contact angle (CA), equilibrium water content, porosity, average pore size, mechanical strength, and f potential measurement were used to evaluate the morphological structure and physical and chemical properties of membranes. Static protein adsorption, filtration, and rejection experiments were conducted to study the antifouling properties, water permeability, and removal ability of the modified membranes. The results show that significant change occurred in the membrane morphology and that better hydrophilicity, water permeability, and antifouling ability were also achieved for the PES/LDH membranes when a proper amount of LDH was used. For example, the CA value decreased from 66.60 to 50.218, and the pure water flux increased from 80.21 to 119.10 L m 22 h 21 bar 21 when the LDH loading was increased from 0 to 2.0 wt %.

“…The elements present and their chemical state (valence) were determined by X‐ray Photoelectron Spectroscopy (XPS) in the synthesized tanninate‐chitosan. The wide XPS scan showed characteristic peaks of N 1s, C 1s, O 1s, and Cl 2p, with the atomic percentage of 4.71 %, 59.44 %, 35.79 % and 0.06 % respectively in Figure . The fitted curve of C 1s showed one peak at binding energies of 286.9 eV for carbon atom present in C−O, C−O‐C and C−N; second peak at 285.2 eV due to C−H and C−C; and third peak at 288.6 eV due to C=O and COOR.…”

The multi‐functional, green and environmental acceptable adsorbents were synthesized from activated chitosan for fluoride ions via mild‐strategies. Chloroacetylation reaction was performed to integrate an active group to the chitosan structural unit. Subsequently, the integrated active group was derivatized with tannin acid, an environmental‐friendly natural polyphenol via a simple reaction. The synthesized products were evaluated for their structures via FTIR, 1H‐NMR, UV, SEM‐EDS, elemental mapping, BET surface analysis, and XPS. The capability of the synthesized green products was appraised for fluoride ions sorption in circumneutral conditions. The results confirmed the maximum sorption capability of ≥97 % even at trace level and also proved remarkable results in competition with competitive ions. The equilibrium sorption data supported the maximum adsorption capacity of 28.57 mg g−1 by the Langmuir model within 60 min at pH 7.0, which is nearly analogous to the experimental data of 22.02 mg g−1 at 10 ppm. Therefore, in conclusion, the proposed green adsorbent is economical, and is even appropriate at almost neutral pH, which designates its applicability for treating drinking water.

“…[134,135] Tannic acid was used for many decades in the treatment of burns. [136][137][138][139] In biomaterial science, it was studied as a collagen [140][141][142][143][144][145][146][147][148][149][150][151][152] and chitosan, [153][154][155][156][157][158][159][160] as well as their mixture [161] cross-linker. Tannic acid has antioxidant and antimicrobial properties.…”

This review provides a report on recent studies of composite materials based on a chitosan and collagen mixture due to their biocompatibility and bioactivity. Those natural polymers are most widely used to obtain biomaterials. However, the materials based on chitosan/collagen complexes present poor mechanical parameters, as well as high swelling behavior and enzymatic degradation rate. Such properties are considered problematic for the material clinical application. An increased interest in composite materials has been observed due to their enhanced physicochemical properties. A composite material preparation involves different compounds addition to natural polymers. Herein, the use of organic and inorganic additives has been reported. Moreover, the potential application of composite materials based on chitosan/ collagen complexes in the tissue engineering science has been discussed.
