“…On other hand, the IR spectra of PES-g-DMAEMAq membrane showed the appearance of new peaks at 954 cm -1 , attributed to the N + group of QA [34] and at 1730 cm -1 , attributed to the stretching peak of the carbonyl group (C=O) of DMAEMAq. Thus, the grafting of DMAEMAq was confirmed by FTIR.…”

Surface modification of hollow fiber polyethersulfone (PES) membranes by UV irradiation induced graft polymerization of (2-dimethylamino)ethyl methacrylate (DMAEMAq) was developed. The grafted layers of the DMAEMAq monomer on the PES membrane surfaces were characterized using attenuated total reflectance Fourier transform infrared analysis and X-ray photoelectron spectroscopy. The performances of the modified PES membranes (PES-g-DMAEMAq) were investigated in terms of both organic fouling and biofouling. Filtration of bovine serum albumin (BSA) as a model protein and Pseudomonas putida (P. putida) as a model bacteria were carried out to evaluate organic antifouling and antibiofouling performances, respectively. The results showed that the membranes surface functionalized with the DMAEMAq monomer showed higher organic antifouling than unmodified PES membranes. A shaking flask test using P. putida also revealed that a PES-g-DMAEMAq membrane with a grafting amount of 4.8 mg/cm 2 showed higher biofouling resistance. That is, almost 99.9% of bacteria were killed by contact with the PES-g-DMAEMAq membrane. Thus, surface functionalization of PES membranes with the DMAEMAq monomer was quite useful for improving antibiofouling and organic antifouling properties.

“…49 Shang et al developed a hydrophobically modified cationic terpolymer consisted of AM, DMC and methacryloxypropyl trimethoxysilane (MAPMS). 50 Terpolymer 27 was synthesized from these monomers by inverse emulsion polymerization (IEP) to allow for adequate dissolution of the hydrophobic monomer. 50 In addition, IEP is an advantageous polymerization technique which produces polymers with high MW and high solid content.…”

“…However, excess dosing of the flocculant resulted in restabilization of the colloidal suspension, where the overall particle surface charge changed from negative to positive. 50 Apart from 27, numerous research groups have also directed their attention towards developing and utilizing hydrophobically modified cationic polymers as flocculants. Cationic terpolymers 28-32 were synthesized through copolymerization between AM and various monomers, including diallyldimethylammonium chloride (DADMAC), 51,52 vinyltrimethoxysilane (VTMS), 52 butylacrylate (BA), 51,53,54 DAC, 53,54 DMC, 55 MMA, 55 and acryloylamino-2-hydroxypropyl trimethylammonium chloride.…”

Flocculation is a common technique that is widely used in many industrial applications to promote solid-liquid separation processes. The addition of a polymeric flocculant allows for destabilization of suspended colloidal particles, and thus significantly increases their sedimentation rate. Polymeric flocculants are generally divided into four categories, which include non-ionic, cationic, anionic, and amphoteric polymers. This minireview article summarises important information on the recent design and synthesis of polymeric materials from these four categories. In addition, their properties and flocculation efficiency are also presented and discussed.

This study examined the effects of acryl-grafted bentonite (AGB) in cationic poly(acrylamide) (CPAAm)/AGB nanocomposites on the flocculation and retention of micrometer-sized talc and ground calcium carbonate (GCC) suspensions used for papermaking. The AGB was synthesized by reacting Na + -bentonite with (3-acryloxypropyl)trimethoxysilane. The graft yield measured by thermogravimetric analysis was ca. 24%. Different concentrations (0, 1.0, 2.9, and 4.9 wt%, designated as CPAAm/AGB-0, -1, -3, and -5, respectively) of AGB were then added to the in situ inverse emulsion copolymerization of acrylamide and [2-(acryloyloxy)ethyl]trimethylammonium chloride to produce the CPAAm/AGB nanocomposites. The nanocomposites improved the flocculation of the GCC suspension model significantly in an AGB concentration-dependent manner. Dynamic drainage analysis revealed a decrease in dewatering time and turbidity from 11.2 s (pure CPAAm) to 8.7 s and from 349 to 33 NTU, respectively, at the same concentration (0.3 wt%) of nanocomposite. The results of the fabrication of handsheets revealed significant improvement (up to 2-8%) in the total retention yield and ash retention yield with increasing AGB concentration at the same GCC content.
