“…Hydrogels based on p(DMAAm) and p(APTMACl) were shown to undergo thermal degradation in one step up to 500 °C and in three steps up to 700°C, respectively [19,23]. The results obtained in this study were compatible with the literature [19,21,32]. p(DMAAm-co-APTMACl) (8:2) was stable until 229 °C; however, above 229 °C there was a substantial loss in copolymer weight.…”

p(DMAAm-co-APTMACl)-based hydrogels were synthesized with different molar ratios by the redox polymerization technique using N,N-Dimethylacrylamide (DMAAm) and 3acrlylamidopropil-trimethyl ammonium chloride (APTMACl) monomers and a crosslinker. In this study, the aim was to improve the swelling properties and dye sorption of the prepared hydrogels. The equilibrium swelling values of hydrogels were determined by the gravimetric method in deionized water and different pH values, and their structural characterizations were examined with Fourier transform infrared spectroscopy (FT-IR) and thermal gravimetric analysis (TGA) techniques. Sorption efficiencies and sorption capacities of the synthesized hydrogels were determined using aqueous solutions containing phenol red dye at 25 °C. In sorption studies, the effects of different concentrations (5-50 ppm) and different pH values (2-12) on sorption were examined. When the swelling analysis in deionized water was examined, there was a significant increase in the equilibrium swelling value of p(DMAAm-co-APTMACl)-based hydrogel as the mole ratio of APTMACl increased. In addition, the increase in the molar ratio of APTMACl was found to increase the phenol red dye sorption capacity and removal percentage. It was observed that p(DMAAm-co-APTMACl) (2:8) hydrogel had maximum sorption capacity in the range of 5-50 ppm and reached 122.2 mg/g. Experimental data showed that the synthesized p (DMAAm-co-APTMACl)-based hydrogels were effective in removing dye from wastewater and could obtain increased dyestuff removal by synthesis with different molar ratios.

“…Swelling assays were carried out with certain amounts of dried gel, hydrogels, and organo-hydrogels placed in water, ethanol, acetone, ethanol/ID water (1:1), acetone/ID water (1:1) and gasoline and at different pHs (2.0–12.0) for 24 h. Swelling tests were performed at room temperature of 25 °C [ 19 , 20 ].…”

In this study, it was aimed to investigate the synthesis, characterization and drug release behaviors of organo-hydrogels containing pH-sensitive Agar (A), Glycerol (G), Sweet Almond oil (Wu et al. in J Mol Struct 882:107–115, 2008). Organo-hydrogels, which contained Agar, Glycerol and different amounts of Sweet Almond oil, were synthesized via the free-radical polymerization reaction with emulsion technique using glutaraldehyde or methylene bis acrylamide crosslinkers. Then, the degree of swelling, bond structures, blood compatibility and antioxidant properties of the synthesized organo-hydrogels were examined. In addition, Organo-hydrogels which loaded with Ceftriaxone and Oxaliplatin were synthesized with the same polymerization reaction and release kinetics were investigated. In vitro release studies were performed at media similar pH to gastric fluid (pH 2.0), skin surface (pH 5.5), blood fluid (pH 7.4) and intestinal fluid (pH 8.0), at 37 °C. The effects on release of crosslinker type and sweet almond oil amount were investigated. Kinetic parameters were determined using release results and these results were applied to zero and first-order equations and Korsmeyer-Peppas and Higuchi equations. Diffusion exponential was calculated for drug diffusion of organo-hydrogels and values consistent with release results were found.

“…Figure 5 shows the SEM images of the surface of PVA/ gelatin blend having different amount of APTEOS. SEM results indicated that the surface of the PVA/ gelatin film without cross-linker was not smooth and characterized by the presence of surface cracks 34 as shown in the form of white particles due to gelatinization. However, with the increase of cross-linker amount, the surface cracks kept on decreasing confirming the successful cross-linking of both PVA and gelatin by APTEOS to form uniform texture.…”

The objective of this work is to fabricate hydrogel films which are biodegradable and also fit for packaging applications. The hydrogel films were prepared by the reaction of polyvinyl alcohol and gelatin with and without 3-aminopropyltriethoxysilane (APTEOS) cross-linker. The hydrogel films were then characterized by FTIR spectroscopy, degree of swelling, TGA, SEM analysis and mechanical testing. The FTIR spectra of the hydrogel films confirmed the presence of both polymers and hydrogen bonding between them. TGA analysis confirmed the increase in thermal stability with the increase of cross-linker amount. SEM analysis confirmed the increase in uniformity of structure with the increase of cross-linker amount. The increase in cross-linker amount resulted in decrease of degree of swelling and increase of tensile strength. The biodegradability of hydrogel films was evaluated by performing soil burial test and found to be decreased with the increase of cross-linker amount. In order to balance the tensile strength and biodegradability, the optimum amount of cross-linker was determined which resulted in the formation of the best performing film. Finally, our best performing film was compared with other hydrogel films reported in the literature. Hence, the hydrogel films cross-linked with APTEOS are biodegradable, having high tensile strength and suitable for packaging purpose.
