“…Figure 2b shows the XRD patterns of pristine clinoptilolite nanoparticles. Comparison of the XRD pattern with the standard one indicates that the crystallinity of clinoptilolite was confirmed and the diffraction peaks appeared at 2θ = 9.85° and 22.4° are due to the Miller indexes of 020 and 004, respectively [40]. Figure 2c shows the X‐ray diffraction patterns of PPy/Clino nanocomposite.…”

In this work, polypyrrole/clinoptilolite nanocomposite was synthesized by in situ surface polymerization of pyrrole using Fe3+ as oxidant, incorporated on the inner and outer surface of clinoptilolite nanoparticles. Formation of nanocomposite and deposition of polypyrrole on the clinoptilolite surface was confirmed and characterized using Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD) patterns, scanning electron microscopy (SEM), and cyclic voltammetry techniques. Elemental analysis showed the loading/incorporation of 9.18 wt% polypyrrole in the clinoptilolite structure. However the electrical conductivity of polypyrrole/clinoptilolite nanocomposite pellets was higher than that of similar pure polypyrrole pellets, synthesized through the chemical oxidation polymerization method using Fe3+ as oxidant without the presence of clinoptilolite nanoparticles. Improved structural order or crystalinity of polypyrrole chains in nanocomposite structure which was confirmed by XRD and SEM results, may be the responsible of higher electrical conductivity of nanocomposite compared to pure polypyrrole although the low content (9.18 wt%) of polypyrrole in nanocomposite. Cyclic voltammetry studies showed that polypyrrole/clinoptilolite nanocomposite is electroactive similar to pure polypyrrole. POLYM. ENG. SCI., 2013. © 2012 Society of Plastics Engineers

“…The loss at 25–200°C was due to weakly bound water. The thermal degradation of the hydrogels was realized in three steps: the emissions of H 2 O, CO 2 , and NH 3 after decomposition of pendant amide and carboxyl groups at 200–320°C, the losses of H 2 O, CO 2 , imides, and nitriles after the main chain breakdown at 320–450°C and the releases during carbonization of the polymer at 450–500°C .…”

In this study, P(NIPAAm‐MAm)/A, which is a new smart polymer on which the temperature sensitivity of N‐isopropyl acrylamide monomer and pH sensitivities of methacrylic acid (MA) and itaconic acid (IA) monomers unite, were prepared by free radical polymerization. The influence of crosslinkers on the properties of polymer and adsorption was studied using two different crosslinkers. These new environmentally multistimuli responsive hydrogels were characterized by FTIR, TG, and DSC. In order to determine the swelling behaviors of polymers, the equilibrium swelling studies were carried out at different temperatures and pHs. With the aim of studying the usability of the prepared polymers in the adsorption of nicotine and its pharmaceutical derivatives, the effects of temperature, pH, and adsorbent mass on adsorption equilibrium were studied.

“…In our studies, the formula compositions (weight ratio) of zeolite NaA and binary XG-alginate polymers were optimized as NaA: XG: alginate: water = 50: (0-10): (3)(4)(5)(6)(7)(8)(9): 1900 in order for well fabricated composites of best adsorptive performance.…”

“…Development of polymer-inorganic hybrid composites provides a promising solution to overcome this drawback [5][6][7][8]. Entrapment of inorganic fillers in polymer matrix has been proved to be a suitable choice to fabricate the hybrid active composites [9,10]. Calcium ion crosslinked alginate hydrogels are nontoxic and biodegradable, which could serve as a natural biopolymer support [11,12].…”
