“…The early generation type of this membrane was made of acetic cellulose, which then has been replaced by a synthetic polymer, such as polysulfone (PSF), polyethersulfone (PES), polyvinylpyrrolidone (PVP), polymethylmethacrylate (PMMA), and polyacrylonitrile (PAN) [2][3][4][5]. Although the early generation and the synthetic polymer types have small pores and are good in transporting urea and creatinine compounds, there are still some problems concerning their permeability and biocompatibility [6]. Therefore, considering that the use of natural materials yields biocompatible products, the utilization of a semi-permeable membrane made of natural biopolymeric resources is very promising and necessary to be further explored and developed [7].…”

This study aims to examine the manufacture, characterization, and in vitro hemocompatibility of glutaraldehyde-crosslinked chitosan/carboxymethyl cellulose (CS/CMC-GA) as a hemodialysis membrane. The CS/CMC-GA membrane was prepared using the phase inversion method with 1.5% CS and 0.1% CMC. The chitosan was crosslinked with glutaraldehyde in various monomers ratios, and the membranes formed were characterized by FTIR, SEM, and TGA. Furthermore, the hydrophilicity, swelling, porosity, mechanical strength, and dialysis performance of the membranes against urea and creatinine were systematically examined, and their in-vitro hemocompatibility tests were also conducted. The results showed that the CS/CMC-GA membranes have higher hydrophilicity, swelling, porosity, mechanical strength, and better dialysis performance against urea and creatinine than chitosan without modification. In addition, the hemocompatibility test indicated that the CS/CMC-GA membranes have lower values of protein adsorption, thrombocyte attachment, hemolysis ratio, and partial thromboplastin time (PTT) than that of pristine chitosan. Based on these results, the CC/CMC-GA membranes have better hemocompatibility and the potential to be used as hemodialysis membranes.

“…The membrane is a semipermeable thin layer that separates two phases (donor and acceptor). Typically, membranes are made from polymers such as polysulfone (PSF), polyethersulfone (PES), and PVDF, which have good hydrolytic stability, thermal stability, easy to generate, and permeable [2]. However, the permeability and biocompatibility of those materials must be enhanced to get the optimum separation [3].…”

“…On the other hand, non-covalent interactions such as hydrogen bonds play a crucial role in many chemical processes to control the molecular structure, even mass transfer in the case of hemodialysis [2]. One way to enhance the functional group for PVDF membrane is the sulfonation process, giving an SO3H cluster in the PVDF structure.…”

Polyvinylidene fluoride (PVDF) membrane and its derivative have been investigated the permeation ability for creatinine and urea. The membrane was made by an inversion precipitation system in N,N-dimethyl acetamide (DMAc) and water as non-solvents. In this study, the modification of PVDF membrane permeability with PEG additives, CBT variations, and sulfonation was successfully carried out. The membrane solidification process was carried out on three variations of the coagulation bath temperature (CBT): 30, 45, and 60 °C. Eight types of membranes were characterized by using FT-IR and TGA/DSC, followed by the analysis of their porosity, hydrophilicity, water uptake, swelling degree, tensile strength, and permeability of creatinine and urea. The FT-IR spectra indicate that PVDF modification has been successfully carried out. The porosity, hydrophilicity, water uptake, and swelling degree values increase with the modification of functional groups. Furthermore, improvements in creatinine and urea permeability and clearances are achieved by increasing CBT and sulfonation in the PVDF/PEG membrane. The presence of sulfonate groups improves the membrane permeability through the interaction of intermolecular hydrogen with water and dialysate compounds. The existence of PEG as a porogen enhanced membrane porosity. Creatinine and urea clearance values increase from 0.29–0.58 and 6.38–20.63 mg/dL, respectively.

In order to prepare a coating with better corrosion resistance, the double‐layer coatings are designed to work together in this article. The double‐layer coatings are made of polyethersulfone and epoxy resin as the matrix resin. Polyaniline (PANI) of different contents was added to the matrix resin by weight to form the primer coats, which was named as d‐0, d‐20, d‐40, d‐60. And polytetrafluoroethylene was introduced into the matrix resin to prepare the surface coats. A two‐layer coating was prepared by coating the surface layer on the primer layer, named as S‐0, S‐20, S‐40, S‐60. The surface morphology of the primer coatings and the cross section morphology of the two‐layer coatings were determined by field emission scanning electron microscopy. The anticorrosion property of the coatings was studied by water absorption, adhesion, salt spray corrosion acceleration test and electrochemical impedance test. The results indicate that the 40 wt% PANI composite coating shows the best corrosion resistance.
