On the mechanism of ion exchange in crystalline zirconium phosphates - IV potassium ion exchange of α-zirconium phosphate

Advanced Nano-biocomposites Based on Starch

“…However, the biocomposites displayed a decrease in the thermal decomposition temperature because the weak thermal stability of the CMC could weaken the interactions between the LDH filler and the starch matrix and facilitate the decomposition of the starch (Wu et al 2011). Furthermore, high LDH content (8 wt %) could result in the agglomeration of the nanofiller in the matrix and thus reduce the mechanical properties and WVP (Wu et al 2011). 14 Nanocomposites Reinforced by a-Zirconium Phosphate Synthetic a-ZrP (i.e., Zr(HPO 4 ) 2 ·H 2 O) exhibits similar structural characteristics to natural MMT clay but has advantages such as high purity and ion exchange capacity and ease of intercalation and exfoliation (Clearfield et al 1972;Clearfield and Berman 1981;Sun et al 2005;Wu et al 2009a). In addition, the particle size and aspect ratio can be manipulated by varying the reaction conditions (Wu et al 2009a).…”

Preparation and characterization of films based on zirconium sulfophenyl phosphonate and chitosan

“…[10][11][12] a-Zirconium phosphate (a-ZrP), Zr(O 3 POH) 2 ÁH 2 O, is one of the most widely used layered phosphates that displays several advantages, including not only a much higher purity, ion-exchange capacity, and an easier process of intercalation, or exfoliation, [13][14][15][16][17][18] but also exhibiting manipulated surface functionality by varying the reaction conditions. 19 Additionally, many studies have demonstrated that a related family of compounds known as zirconium phosphonates, Zr(O 3 PR) 2 , which also possesses a layered structure, can be synthesized using phosphonic acids instead of phosphoric acid. In these materials, the attractive interactions of the R groups that project into the interlayer region are responsible for stacking the zirconium planes.…”

A novel conductivity composite based on polyaniline/zirconium phenylphosphonate

“…A large number of layered materials, including montmorillonite and α‐zirconium phosphate (α‐ZrP), have been studied as composite materials for PANI and have already proven to effective in improving the electrical properties of PANI 16, 17. Compared to natural montmorillonite clay, α‐ZrP exhibits several additional advantages, including a much higher purity and ion‐exchange capacity, an easier process of intercalation, and a manipulated surface functionality 18–20. Thus, α‐ZrP is one of the most extensively used layered phosphates 21, 22.…”
