“…After modification, ZrSP offered the highest interlayer spacing at 14.5 Å , suggesting a significant intercalation of sulfonic acid and phosphonate groups into the interlayer gallery. Also all the peaks present in the ZrO 2 remarkably shifted to lower BraggÕs angle at 6.06°, 19.97°, and 11.94°which is caused by treatment with hydrofluoric acid (HF), that is further supported by the previous study (Ref 35).…”

A candid approach to analyze the performance characteristics of phenyl phosphonate-functionalized zirconium oxide and pure zirconium oxide (ZrO 2 ) fillers reinforced chitosan nanocomposites and their suitability as a potential biomaterial for the development of transducer surface in biosensing device has been investigated in this communication. Functionalization of ZrO 2 has been carried out using sulfophenylphosphonate which was confirmed using Fourier transform infrared spectrographs. The electrostatic intercalation of chitosan with filler particles was monitored using electrochemical impedance analyzer which exhibits lowest bulk resistance which is highly effective for ionic switching. Incorporation of zirconium sulfophenylphosphonate (ZrSP) the ionic conductivity of the chitosan film attained a value of 1.2 3 10 26 S/cm as compared to the unmodified one which is a prefeasibility work for the fabrication of biosensing platform. Variation in performance characteristics has been evaluated through morphological and thermal characterization. TGA and DSC analysis reveal that the thermal stability and decomposition temperature of the nanocomposites were improved by the addition of reinforcing filler particles. XRD and SEM and TEM results support the above assumption. The continuous alignment of the proton transfer channels of the nanocomposites was thoroughly investigated by AFM analysis which revealed phase morphology for improved enzyme entrapment. Further, surface functionalized nanofillers result considerable increment of mechanical properties in terms of elastic modulus and tensile stress.

“…Aminoalkanes were intercalated into λ-ZrP to use as latent polymerization catalyst of glycidyl phenyl ether (GPE) 15 . The intercalation of n-alkylamines (n-butylamine, n-heptylamine and n-decylamine) into layered zirconium benzylamino-N,N-dimethylphosphonate phosphate (ZBMPA) ZBMPA was reported by Zeng et al 16 .…”

In order to search nanofiller for controlling release of drugs lamellar α-zirconium phosphate (α-ZrP) was modified with ether-amine oligomer (E-A). Synthesis and chemical modification followed specific reaction conditions and different EA:ZrP ratios. Infrared spectra showed strong interaction between P-OH and NH 2 groups. Thermogravimetric curves showed that ether-amine oligomer was incorporated by ZrP. Interlamellar space of α-ZrP increased at least four times indicating intercalation. The relaxometry analysis indicated that α-ZrP molecular mobility changed according to the etheramine amount. The scanning electron microscopy/energy dispersive analysis revealed the presence of octadecylamine inside the α-ZrP galleries. The results showed that P-OH group (Brønsted acid) and amine group (Brønsted base) reacted to each other, resulting in an ionic bond PO-+ 3 HN-[-(CH 2-CH 2-O) m-(CH 2-C-H(CH 3)-O) n-]. Partially intercalated nanofiller were achieved.

“…(a), the broad band at 3446 cm −1 was assigned to ―OH stretching of water, which was adsorbed on the surface of ZrNP . The sharp peaks at 1439 and 1158 cm −1 were attributed to P―C and PO stretching vibration, and the strong peaks at 748 and 692 cm −1 corresponded to the aromatic ring C―H stretching vibration and phenyl ring deformation bending. In addition, we could find two peaks at 1355 and 1535 cm −1 in the FTIR spectrum of ZrNP, representing the symmetric and non symmetric stretch of NO band, respectively.…”

Three types of zirconium phosphonate (org‐ZrP) with different functional groups (―COOH, ―SO3H, ―NO2) were prepared first and then added into chitosan (CS) matrix, respectively. The effect of these functional groups on structure, morphologies, and mechanical properties of chitosan films was investigated. The Fourier transform infrared spectroscopy revealed that org‐ZrP had intensely interacted with chitosan in the composites because of introducing functional groups on the fillers. The composite films filled with zirconium sulfophenylphosphonate exhibited the best mechanical properties among the three org‐ZrP fillers. These differences of reinforcement effect appeared to be caused by the difference of interfacial interactions between the org‐ZrP fillers and matrix. The stronger the interfacial interactions are, the better the reinforcement effect is. In addition, the moisture uptake (Mu) of CS/org‐ZrP‐n composite films depended on the hydrophilic property of functional groups. It was found that zirconium nitrophenyl phosphonate showed the best moisture barrier property due to its poor absorbability for water molecules. Copyright © 2014 John Wiley & Sons, Ltd.
