“…Recently, a number of techniques have been investigated to improve the hydrophilicity and anti-fouling performance of membranes including graing hydrophilic species to the top surface of pre-formed ultraltration membranes, 24,25 hydrophilic polymer coatings, [26][27][28] cold plasma treatment, [29][30][31][32][33] covalent attachment of hydrophilic polymers, 34,35 and incorporating hydrophilic llers such as inorganic nanoparticles. 36 Among these methods, graing hydrophilic molecules to the top surface of membranes is a simple, practical and economical addition to existing membrane manufacturing processes, without requiring heat treatment or any other hazardous conditions.…”

Hydrophilic bromomethylated poly(phenylene oxide) (BPPO) ultrafiltration membranes were prepared via a single-step reaction with diethylenetriamine (DETA). The resulting DETA modified BPPO membranes are characterised using FTIR-ATR, SEM, fouling resistance, filtration test and contact angle measurements. Although permeation flux was adversely affected, the chemically bound DETA leads to a significant increase in surface hydrophilicity and anti-fouling properties of BPPO/DETA membranes.The composite BPPO/DETA membranes show a considerable reduction in membrane fouling and enhanced BSA rejection, with foulants easily removed by normal cleaning methods. Herein, a facile surface modification with DETA is shown to be an effective means of enhancing the flux recovery ratio and anti-fouling properties of BPPO membranes.

Plasma based surface modification of Poly (dimethylsiloxane) electrospun membrane proper for Organ On a Chip applications

Constructing of the scaffolds for cell culture applications has long been of interest for engineering researchers and biologist. In this study, a novel process is utilized for construction of suitable membrane with a high mechanical strength and appropriate surface behavior. Poly (dimethylsiloxane) (PDMS) is electrospun into fine fibers using poly (methyl methacrylate) (PMMA) as the carrier polymer in different weight ratios.Since the surface behavior of all PDMS substrates is moderately hydrophobic (120 < contact angle (CA) < 150), the electrospun membranes with higher PDMS ratios show slightly higher hydrophilicity. Direct plasma treatment is utilized to change the interfacial wettability of the membrane. Applying plasma changes the surface energy and renders the PDMS/PMMA substrates superhydrophilic (CA<5). In the following, the mechanical properties of the membrane are evaluated by the tensile test, and the results confirm the suitable mechanical strength of electrospun PDMS for cell culturing objectives (yield stress of more than 10 kPa). Also, changing the PDMS ratio doesn't significantly affect the total stiffness of the membrane. Thus, applying the proposed fabrication protocol provides a proper platform for cell viability and proliferation which have been proven by the results of MTT assay.2

“…[3,4] We suggest herein that grafting environmentally responsive polymers onto synthetic membranes by using simple inexpensive methods such as photograft-induced polymerization, which can be easily incorporated into the membrane synthesis process, may offer an alternative method to the approaches that use traditional protein-adhesion-resistant monomers such as polyethylene glycol and other hydrophilic monomers. [3,5] Specifically, we combine two known technologies, a patented UV-grafting process with the well-known photoresponsive properties of spiropyran molecules, to produce an optically reversible switching membrane surface.…”

Lighting the way: Through the combination of a UV‐grafting process with the photoresponsive properties of spiropyran molecules, an optically reversible switching membrane surface was developed. This process can be used in preference to inducing physical movement of long‐chain SAMs toward an electrode and as a result improve many industrial opportunities including those dependent on surface wettability and molecular adhesion.
