Preparation and characterization of mesoporous zirconium phosphates from alkyl phosphates

Phase Morphology and Performance of Supertough PLA/EMA–GMA/ZrP Nanocomposites Prepared through Reactive Melt-Blending

“…However, the difference with MMT clay is that the layers of ZrP are formed by zirconium atoms and the oxygen atoms of phosphate groups are connected with them. The layers are also formed by three oxygen atoms, which are contributed by each phosphate molecule and the phosphate molecule also donating one hydroxyl group pointing into the interlayer space . Due to the remarkable structure, ZrP has many excellent features, such as good chemical and thermal stability, high mechanical strength, perfect particle size, ease of surface functionality control, and high purity, aspect ratio, and ion-exchange capacity. − A strong interaction of interfacial between ZrP and polymer composites can be achieved by miscibility reaction, and the nanofiller ZrP can evenly disperse in a polymer matrix.…”

Synthesis, structure and some properties of zirconium phosphate/oxide support compositions

“…Thus, the spectrum of bulk ZrP contains a. and b. centered around 425, 510, 595, 710, and 1038 cm -1 (Fig. 4, curve a) which are attributed to deformation and stretching vibrations of P-O bonds in PO 4 3- [4,28,29]. The embedding of ZrP into the siliceous framework during the sol-gel synthesis results in shift of a.b.…”

Reactive coaxial electrospinning of ZrP/ZrO2 nanofibres

“…24 Aer electrospinning, the 31 P NMR analysis of the nanobres (Fig. 4) shows overlapping peaks around 0 to À15 ppm with three main peaks at À4.4, À12.6, and À15.5 ppm which indicates that the as-spun mat contains alkyl phosphate species due to the solvent used, however the main peak at À4.4 ppm is most likely due to alkyl-terminated, Q 1 phosphate species due to the reaction between the alkyl phosphate formed from P 2 O 5 and the alcohol solvent 25 and the zirconium precursor. The lack of a peak at zero due to phosphoric acid indicates that most of the available phosphorus reacted immediately, and little unreacted P 2 O 5 remained to react with moisture in the atmosphere to form phosphoric acid.…”
