The selection of polyethersulfone/polyvinylpyrrolidone films for industrial application using the multiple‐criteria decision‐making approach

Abstract

The polyethersulfone (PES)-based composite polymers have been extensively studied for many years as the core of various scientific activities, such as fuel cell production, water treatment, reverse osmosis, ultrafiltration, nanofiltration, and gas separation, which represent a significant field of research for several applications. In the present study, PES and polyvinylpyrrolidone-coated magnetic coreshell nanoparticles (NPs) are synthesized. Following this, a range of these NPs and PES blend polymers are prepared. Then, analyzing methods are used for identification and characterization of a variety of these samples. Since some properties of the samples have been improved, and others are attenuated, the best composition could not be selected from the samples without a logical process. To do so, a multiple-criteria decision-making (MCDM) technique that considers all the desired parameters is utilized. A MCDM algorithm is applied to create a ranking of alternative properties from the best to the worst, alongside mathematical calculations which accounts for the relative importance of the criteria. Results have shown that PES film with 15% of polymer-coated NPs presents the best performance based on the desired properties.

Performance evaluation of polyethersulfone membranes modified with poly (acrylic acid‐co‐N‐vinyl pyrrolidone) grafted mesoporous carbon nitride for effective removal of cadmium(II) from wastewater

“…The copolymerization of AA and VP on the linker@MCN surface was accomplished using 2 mol% AIBN concerning monomer content at 70°C for 24 h, as shown in Scheme 1, steps 5 and 6. For separating poly(AA‐ co ‐VP) grafted MCN, the resultant mixture was centrifuged and washed with isopropyl alcohol several times 49 …”

Sustainable high-efficiency removal of cationic and anionic dyes using new super adsorbent biochar: performance, isotherm, kinetic and thermodynamic evaluation

“…7 The accumulation of toxic and carcinogenic dyes in the human body can lead to severe organ failure which can include liver and renal serious damage, and even irrecoverable neural system impairment. 8 Multiple approaches have been established for decontamination of wastewater such as membrane processes, 9,10 sedimentation, coagulation, 11 precipitation, electrochemical processes, 12 adsorption, biological remediation, and ion exchange treatment. 13 Adsorption is generally favored amongst various decontamination methods for water purification since it is one of the most efficacious, straightforward, renewable, compatible, and propitious wastewater treatment processes and shows remarkable resistance to noxious contaminants.…”

Biocompatible organic coating fabrication via polymer/clay nanocomposites: Evaluation of mechanical improvements

“…[3][4][5][6][7] PVP owns its biocompatibility to its chemical structure resembling amino acids, which are widely discussed in the literature. [8][9][10][11][12] The bentonite nanoclay is mostly montmorillonite (MMT)-based natural reinforcement, 13 which is abundant in nature. Thanks to their biocompatibility, nanoclays are widely utilized for biomedical applications.…”
