“…According to previous studies, the researchers prepared stripped ZrP with surfactant and also found no ZrP peaks in their XRD patterns. 30 , 31 Due to the exfoliation effect, ZrP was likely to transform into an amorphous state, which led to the disappearance of the ZrP characteristic peaks. Similarly, in this study, the existence of Pluronic L64 in the calcination process might affect the crystallization of ZrP, possibly causing the absence of ZrP characteristic peaks in the XRD and GIXRD results.…”

Background Sandblasted/acid-etched titanium (SLA-Ti) implants are widely used for dental implant restoration in edentulous patients. However, the poor osteoinductivity and the large amount of Ti particles/ions released due to friction or corrosion will affect its long-term success rate. Purpose Various zirconium hydrogen phosphate (ZrP) coatings were prepared on SLA-Ti surface to enhance its friction/corrosion resistance and osteoinduction. Methods The mixture of ZrCl 4 and H 3 PO 4 was first coated on SLA-Ti and then calcined at 450°C for 5 min to form ZrP coatings. In addition to a series of physiochemical characterization such as morphology, roughness, wettability, and chemical composition, their capability of anti-friction and anti-corrosion were further evaluated by friction-wear test and by potential scanning. The viability and osteogenic differentiation of MC3T3-E1 cells on different substrates were investigated via MTT, mineralization and PCR assays. Results The characterization results showed that there were no significant changes in the morphology, roughness and wettability of ZrP-modified samples (SLA-ZrP0.5 and SLA-ZrP0.7) compared with SLA group. The results of electrochemical corrosion displayed that both SLA-ZrP0.5 and SLA-ZrP0.7 (especially the latter) had better corrosion resistance than SLA in normal saline and serum-containing medium. SLA-ZrP0.7 also exhibited the best friction resistance and great potential to enhance the spreading, proliferation and osteogenic differentiation of MC3T3-E1 cells. Conclusion We determined that SLA-ZrP0.7 had excellent comprehensive properties including anti-corrosion, anti-friction and osteoinduction, which made it have a promising clinical application in dental implant restoration.

“…The "tortuous pathway" strategy has largely been adopted to impart barrier properties of the assembled hybrids containing inorganic nanosheets, which are generally considered impermeable for guest molecules. [53,[85][86][120][121][122][123][124][125][126] α-ZrP is a particularly ideal candidate because it can be completely exfoliated into single-layer nanosheets and the aspect ratio of the nanosheets can be well-controlled by synthesizing layered α-ZrP crystals with various lateral dimensions as discussed above. When single-layer α-ZrP nanosheets are well dispersed, their concentration, aspect ratio, curvature, and orientation dictate the barrier properties of the assembled hybrids.…”

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.

Gummy Nanoparticles with Glassy Shells in Electrostatic Nanocomposites

Nanocomposites with unusual and superior properties often contain well-dispersed nanoparticles. Polydimethylsiloxane, PDMS, offers a fluidlike or rubbery (when cross-linked) response, which complements the high-modulus nature of inorganic nanofillers. Systems using PDMS as the nanoparticulate, rather than the continuous, phase are rare because it is difficult to make PDMS nanoparticles. Aqueous dispersions of hydrophobic polymer nanoparticles must survive the considerable contrast in hydrophobicity between water and the polymer component. This challenge is often met with a shell of hydrophilic polymer or by adding surfactant. In the present work, two critical advances for making and using aqueous colloidal dispersions of PDMS are reported. First, PDMS nanoparticles with charged amino end groups were prepared by flash nanoprecipitation in aqueous solutions. Adding a negative polyelectrolyte, poly(styrene sulfonate), PSS, endowed the nanoparticles with a glassy shell, stabilizing them against aggregation. Second, when compressed into a nanocomposite, the small amount of PSS leads to a large increase in bulk modulus. X-ray scattering studies revealed the hierarchical nanostructuring within the composite, with a 4 nm PDMS micelle as the smallest unit. This class of nanoparticle and nanocomposite presents a new paradigm for stabilizing liquidlike building blocks for nanomaterials.
