“…The peaks at 1249 and 1041 cm –1 represent the P–OH in-plane and out-of-plane vibrations from ZrP. The peak at 1105 cm –1 corresponds to the C–O stretching of M1000 . The peak at 1003 cm –1 corresponds to the C–N stretching from M1000 and APTMS .…”

“…At present, it is difficult to prepare polymer nanocomposites containing exfoliated 2D nanoplatelets due to the energetic and entropic barriers that need to be overcome for nanoplatelets to remain exfoliated in a polymer matrix. To date, nearly full exfoliation of 2D nanoplatelets in the polymer was only achieved mainly through in situ polymerization. ,,,− The preparation of the polymer nanocomposite via solvent or melt mixing is more favorable compared to the in situ polymerization approach because of the cost and ease of fabrication at a large scale . Here, a simple solution mixing method is shown to achieve full exfoliation of ZrP in PEVAc.…”

“…The peak at 1105 cm −1 corresponds to the C−O stretching of M1000. 12 The peak at 1003 cm −1 corresponds to the C−N stretching from M1000 and APTMS. 28 There is no significant difference in the FTIR spectra between ZrP-M1000 and ZrP-MA due to the low grafting ratio of APTMS on ZrP.…”

“…As reported, amines like propylamine, tetrabutylammonium hydroxide [TBA][OH], and polyether monoamines (Jeffamine M600, M725, and M1000 from Huntsman) can diffuse into the ZrP interlayer and disrupt the hydrogen bonding network, leading to the exfoliation of ZrP . However, the presence of the low molecular weight M1000 in polymer matrices may lead to deterioration of the properties, such as lowering epoxy T g and modulus, even though ZrP is fully exfoliated in the polymer matrix. , …”

Jeffamine M1000 is amphiphilic and has been shown to exfoliate ZrP in many solvents and polymer matrices.…”

Poly(ethylene-co-vinyl acetate) (PEVAc) nanocomposites containing exfoliated α-zirconium phosphate (ZrP) have been prepared using a simple solution mixing method to improve their barrier and mechanical properties. ZrP was pre-exfoliated with a surfactant, followed by additional targeted surface functionalization and surfactant exchange to allow for hydrogen bonding of ZrP with the acetate functionality on PEVAc and to improve ZrP surface hydrophobicity. The solvent is found to play an important role in stabilizing ZrP exfoliation in the presence of PEVAc to retain full exfoliation and homogeneous dispersion upon the removal of the solvent. The PEVAc/ZrP nanocomposite exhibits greatly improved oxygen barrier, melt strength, and mechanical properties. The usefulness of the present study for the preparation of olefinic polymer nanocomposites is discussed.

α-Zirconium phosphate (Zr(HPO 4 ) 2 ⋅H 2 O, α-ZrP) is an inorganic layered compound. Since the first report of crystalline α-ZrP in 1964, thanks to its simple synthesis and unique physiochemical properties, α-ZrP has found widespread application in many fields including mechanical reinforcing, barrier improvement, flame retardancy, anticorrosion, catalysis, environment, energy, and medicine. Because of the ease of exfoliation of α-ZrP to obtain single-layer nanosheets, as well as its rich surface chemistry thanks to the high density of orderly arranged surface acidic hydroxyl groups, α-ZrP single-layer nanosheets are ideal building blocks for self-assembly or assembly with other chemicals. The assembly of α-ZrP nanosheets could form a randomly dispersed structure (isotropic), roughly ordered structure (nematic), or highly ordered structure (smectic) within liquid colloids or solid hybrids (including hydrogels). Thanks to the combination of the unique structures and the novel functions of the components, the assembled materials have found a wide verity of applications due to their excellent properties. In this article, the methods to synthesize α-ZrP, the approaches and mechanisms to exfoliate α-ZrP, and the strategies to assemble α-ZrP nanosheets to form various structures, as well as the applications of the assembled materials are reviewed. The emerging prospects of α-ZrP nanosheets as a key material in next-generation functional applications are envisioned.
