“…1 confirmed the crystalline structure of ZrP. Ethylamine (75%, solution in water, Aldrich) and three salts, hexadecyltrimethylammonium bromide (CTBA, C19H42NBr, ≥98%, Sigma), benzyldimethylhexadecylammonium chloride (HDBAC, C25H46NCl·H2O, Sigma) and [3-(3,4-Dimethyl-9-oxo-9H-thioxanthen-2-yloxy)-2-hydroxy-propyl] trimethylammonium chloride (DOHAC, C21H26NClO3S, 97%, Aldrich) were used as intercalating agents for preparation of organically-modified ZrP (OZrP) by cation exchange [27]. The structures of the salts are shown in Fig.…”

Abstract:The flame retardancy and thermal stability of ammonium polyphosphate/tripentaerythritol (APP/TPE) intumescent flame retarded polystyrene composites (PS/IFR) combined with organically-modified layered inorganic materials (montmorillonite clay and zirconium phosphate), nanofiber (multiwall carbon nanotubs), nanoparticle (Fe2O3) and nickel catalyst were evaluated by cone calorimetry, microscale combustion calorimetry (MCC) and thermogravimetric analysis (TGA). Cone calorimetry revealed that a small substitution of IFR by most of these fillers (≤2%) imparted substantial improvement in flammability performance. The montmorillonite clay exhibited the highest efficiency in reducing the peak heat release rate of PS/IFR composite, while zirconium phosphate modified with C21H26NClO3S exhibited a negative effect. The yield and thermal stability of the char obtained from TGA correlated well with the reduction in the peak heat release rate in the cone calorimeter. Since intumesence is a condensed-NOT THE PUBLISHED VERSION; this is the author's final, peer-reviewed manuscript.

“…It has been used widely in the fabrication of metal phosphonate reinforced polymeric composites. [25][26][27][28] Besides, metal phosphonates can also find applications in the field of biomaterials due to the natural occurring nature of phosphate. According to Pan et al, [24] the crystallization of PLLA has been significantly accelerated and the tensile and storage moduli of PLLA have been reinforced by the incorporation of PPZn.…”

The nucleating effect of zinc phenylphosphonate (PPZn) was investigated on the as‐bacterially synthesized poly(3‐hydroxybutyrate) [P(3HB)] and poly[(3‐hydroxybutyrate)‐co‐(3‐hydroxyhexanoate)]s [P(3HB‐co‐3HHx)s] in order to improve their crystallization rate. PPZn is found an efficient nucleating agent on the crystallization of P(3HB) and P(3HB‐co‐3HHx) with low 3HHx unit content. The nucleation mechanism is proposed to be epitaxial nucleation. Both the comonomer‐unit composition and its distribution of P(3HB‐co‐3HHx)s were found exhibiting significant effect on the nucleating effect of PPZn. It is found that PPZn is more efficient on nucleating the crystallization of P(3HB‐co‐3HHx) with a broader comonomer‐unit compositional distribution than that with a narrower distribution. magnified image

“…Accordingly, several experimental methods have been developed to synthesize polymer/-ZrPO 3 inorganic nano-composites, including exfoliation-adsorption, in-situ intercalative polymerization, melt intercalation and template synthesis [37][38][39][40]. There have been several experimental investigations on polymer/-ZrPO 3 nano-composites including poly (ethylene terephthalate)(PET)/-ZrPO 3 [41], epoxy/-ZrPO 3 [42][43][44][45], polyacrylamide (PAM)/-ZrPO 3 [46,47], poly(vinyl alcohol) (PVA)/-ZrPO 3 [48][49][50][51][52][53], and starch/-ZrPO 3 [54,55]. These nano-composites will be reviewed in detail in the following paragraphs and the combustion and mechanical properties of some nano-composites are listed in Tables 1 and 2.…”

“…In a recent work by Zhang [46], a PAM/-ZrPO 3 polymer nano-composite was synthesized by exfoliation-adsorption and in-situ intercalative polymerization. The results indicated that the interactions between PAM and -ZrPO 3 include electrostatic adsorption and some weak interactions such as hydrogen bonding or protonation, as shown in Figure 3.…”

The layer structured zirconium phosphate (ZrPO 3 ) can be intercalated with atoms, molecules, small organic groups and even polymers. The structures and properties of the ZrPO 3 intercalation compounds can be deliberately tuned, leading to promising potential applications in many fields. This article provides a brief review on the experimental results of the ZrPO 3 intercalation compounds, with the focus on the polymer/-ZrPO 3 nano-composites. The computer simulations of the ZrPO 3 intercalation compounds at the atomic level play a significant role in designing and understanding the properties of ZrPO 3 , and in the promotion of the applications of compounds. -Zirconium phosphate, intercalations, nano-composites Citation:Tang M, Yang T S, Zhang Y.
