“…As well, water soluble forms of cellulose containing quaternary ammonium salt derivatives [15,16] have also been explored. Previous reports [12,17] indicate that the point of zero charge (PZC) of cellulose-based hydrogels range from 6 to 8; thus, affording suitable uptake properties of both anionic and cationic adsorbates according to the pH conditions.…”

Quaternized (QC) and cross-linked/quaternized (CQC) cellulose hydrogels were prepared by cross-linking native cellulose with epichlorohydrin (ECH), with subsequent grafting of glycidyl trimethyl ammonium chloride (GTMAC). Materials characterization via carbon, hydrogen and nitrogen (CHN) analysis, thermogravimetric analysis (TGA), and Fourier transform infrared (FTIR)/13C solid state NMR spectroscopy provided supportive evidence of the hydrogel synthesis. Enhanced thermal stability of the hydrogels was observed relative to native cellulose. Colloidal stability of octanol and water mixtures revealed that QC induces greater stabilization over CQC, as evidenced by the formation of a hexane–water Pickering emulsion system. Equilibrium sorption studies with naphthenates from oil sands process water (OSPW) and 2-naphthoxy acetic acid (NAA) in aqueous solution revealed that CQC possess higher affinity relative to QC with the naphthenates. According to the Langmuir isotherm model, the sorption capacity of CQC for OSPW naphthenates was 33.0 mg/g and NAA was 69.5 mg/g. CQC displays similar affinity for the various OSPW naphthenate component species in aqueous solution. Kinetic uptake of NAA at variable temperature, pH and adsorbent dosage showed that increased temperature favoured the uptake process at 303 K, where Qm = 76.7 mg/g. Solution conditions at pH 3 or 9 had a minor effect on the sorption process, while equilibrium was achieved in a shorter time at lower dosage (ca. three-fold lower) of hydrogel (100 mg vs. 30 mg). The estimated activation parameters are based on temperature dependent rate constants, k1, which reveal contributions from enthalpy-driven electrostatic interactions. The kinetic results indicate an ion-based associative sorption mechanism. This study contributes to a greater understanding of the adsorption and physicochemical properties of cellulose-based hydrogels.

“…Another case is polyamide-66, which was treated with a plasma polymerization process to improve the fire retardant property. 9 Methyl diallyl ammonium salt (MDAA) was synthesized according to the method described by Tö pfl 10 in our previous study, 11 in which MDAA was used to combine with dimethyloldihydroxyethyleneurea (DMDHEU) as crosslinking agent. The results revealed that the vinyl and epoxy groups could react with cellulose to change the crease recovery properties.…”

In this study, the effect of argon-plasma treatment on the grafting of methyl diallyl ammonium salt (MDAA) onto polyamide-6 film and the anti-bacterial and surface properties of the plasma-and graft-treated film were investigated. The grafting amounts of MDAA caused by argon-plasma treatment increased with the increase in the plasma exposure time and plasma power. The analyses of Fourier transform infrared (FT-IR) spectroscopy and electron spectroscopy for chemical analysis (ESCA) spectra revealed that the epoxy and vinyl groups of MDAA could be grafted on the argon-plasma treated polyamide-6 film. The survey spectra of ESCA, the patterns of atomic force microscopy (AFM), and the spectra from scanning electron microscopy (SEM) were employed to certify the surface modification of argon-plasma treated and the argon-plasma treated/MDAA grafted polyamide-6 films. Argon-plasma treatment could generate the functional group and increase the roughness on the surface of polyamide-6 film. This phenomenon could enhance the grafting effect of MDAA. The anti-bacterial property of argon-plasma treated/MDAA grafted polyamide-6 film was excellent. This argon-plasma treated/MDAA grafted polyamide-6 film was expected to be applied on the field of packing.

“…The absorption band of –NH2 in O‐MDAACS still existed but was shifted to 1647 cm −1 . Compared with chitosan, O‐MDAACS exhibited bands at 995 cm –1 for –CH=CH 2 and at 1487 cm –1 for the methyl group . In addition, a strong absorption band at 1096 cm −1 was observed, attributed to CH 2 ‐O‐CH 2 of O‐MDAACS.…”

“…Chitosan derivatives with a quaternary ammonium group are soluble in both acidic and basic physiological circumstances, so they might be good candidates as polycationic antimicrobial agents. In the literature, a quaternized chitosan, which is synthesized by the reaction of chitosan with glycidyl trimethylammonium chloride, has been reported to have good moisture retention capacity and antimicrobial activity …”

In this study, a derivative of chitosan, O-hydroxy-2,3-propyl-N-methyl-N,N-diallylammonium chitosan methyl sulfate (O-MDAACS), was synthesized by reacting chitosan with methyl diallyl ammonium. The O-MDAACS was confirmed by Fourier transform infrared spectroscopy and 1 H NMR. Characterization was conducted including X-ray diffraction, differential scanning calorimetry and thermogravimetry. The antibacterial activities of O-MDAACS against Staphylococcus aureus and Klebsiella pneumoniae were evaluated. The minimum inhibitory concentrations on O-MDAACS were 3.7% and 23% of those on chitosan against S. aureus and K. pneumonia, respectively. The minimum bactericidal concentrations on O-MDAACS were 7% and 36% of those on chitosan against S. aureus and K. pneumonia, respectively. Thus the antibacterial activity of O-MDAACS was higher than that of chitosan. The cytocompatibility was evaluated in vitro with L929 fibroblasts. The results showed that after 72 h incubation the cell viability on O-MDAACS was about 12% and 59% higher than those on chitosan and on control, respectively.
