“…Specifically, the surface of PES-SF 1 revealed a skin-like structure more than the surface of PES-SZ 1 . It seems that the hydrophilicity of PES-SF 1 membranes helped to smooth the membrane surface more than in PES-SZ 1 of nanoparticles as the ratio increased in PES nanocomposites has been previously reported. 45 The EDX results in Figure 6 revealed the elements found in pure PES, which are sulfur, oxygen, and carbon.…”

“…Natural polymers such as chitosan, cellulose, and alginate, have attracted researchers in many medial and environmental applications . Although natural polymers have excellent properties including nontoxic, biodegradable, and abundant materials, they have been also known to exhibit less thermal and mechanical stabilities in comparison to synthetic polymers such as poly(vinyl alcohol) or thermoplastic polymers such as polyethersulfone (PES).…”

In this work, a novel modified polyethersulfone (PES) membrane was made by blending PES with organic biomolecules which were N1,N4‐bis(4‐sulfamoylphenyl)terephthalamide (SF), and N1, N4‐bis[4‐(N‐(5‐methylisoxazol‐3‐yl)sulfamoyl)phenyl]terephthalamide (SZ) to afford PES‐SF and PES‐SZ membranes. Antifouling properties of these modified membranes were examined against different types of bacteria and a fungus as well as by measuring the contact angle. The results showed the addition of these organic additives to PES membranes did not improve the hydrophilicity and exhibit any microbial activity. Thus, Cu2O nanoparticles were used with different concentrations to afford PES‐SF‐Cu2O and PES‐SZ‐Cu2O nanocomposites membranes. The results showed when Cu2O nanoparticles (3 wt %) was added to PES‐SF3 and PES‐SZ3 membranes, both membranes showed the best hydrophilicity with 67° for PES‐SF3‐Cu2O membrane and 77° for PES‐SZ3‐Cu2O membranes. PES‐SF3‐Cu2O and PES‐SZ3‐Cu2O membranes showed antibacterial against Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus. To evaluate the anticoagulant activity of the PES‐SF and PES‐SZ membranes, the clotting times using the activated partial thromboplastin time (APTT) and prothrombin time (PT) were measured. The results showed PT level was prolonged for the pure PES membrane with 13 s and for PES‐SF1 membrane with 12.4 s while the PES‐SZ1 membrane showed no difference from the control (pure plasma). Contrary to the PT factor, APTT level of the PES‐SF membrane showed the longest time with 43 s. The results of APPT and PT seemed somewhat satisfactory for the PES‐SF while the PES‐SZ membrane did not show any difference from the control sample. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

“…The assembly of biopolymers to clay minerals giving rise because of their synergistic effect regarding both the mechanical and the absorption properties of these systems . Recently, several attempts have been made to composite the adsorbents with biopolymers, such as poly(vinyl alcohol), carrageenan, chitosan, alginate, cellulose, and silk fibroin which led to enhancement in their adsorption capacity. Gelatin (GE) is a natural biopolymer and has a long history of safe use in cosmetic, pharmaceutical and food industries .…”

This work aimed to fabricate nanocomposites using low‐cost and natural materials for fast and efficient dye adsorption from wastewater. To achieve this, fibrous sepiolite clay was incorporated into the gelatin (GE) biopolymer. The obtained nanocomposites were characterized by Fourier transform infrared spectroscopy and scanning electron microscope techniques. The effects of sepiolite/GE ratio, adsorbent dosage, solution pH, contact time, and initial dye concentration on the adsorption capacity of nanocomposites were well studied and optimized through batch adsorption study. Kinetics, isotherms, and thermodynamics analysis were also performed for methylene blue adsorption. The adsorption data were better fitted with the pseudo‐second‐order and Langmuir isotherm models. The prepared nanocomposites demonstrated a fast and efficient adsorption performance toward the MB dye with the maximum adsorption capacity as high as 684.8 mg g−1 within only an equilibrium time of 30 min, which revealed their promising potential in wastewater treatment. © 2019 Wiley Periodicals, Inc.
