Willcock, Dispersion of upcon-verting nanostructures of CePO4 using rod and semi-spherical morphol-ogies into transparent PMMA/PU IPNs by the sequential route, Polymer142 (2018) 356–374.Value of the data This data can be useful for comparing the dispersion of CePO4 nanostructures in similar systemsand how the morphology affects the structural, thermal and mechanical properties. Data highlights the influence of dispersed CePO4 in different PMMA/PU ratios. This article will serve as a guideline to select the amounts adequate for dispersing CePO4 intoPMMA/PU.1. DataPlastic materials with good durability can be obtained from the synthesis of interpenetratingpolymer networks (IPNs) while incorporating luminescent nanostructures such as Fluoro-functionalized nanostructured silica (FSiO2), silica (SiO2), carbon black (CB), barium titanate(BaTiO3), polyaniline, and cerium phosphate (CePO4) [1–6].The dataset of this article shows additional information about the dispersion of CePO4, in rods andsemi-spherical morphologies, into transparent PMMA/PU IPNs. Initially, this study provides facts ofthe elements in CePO4. For this reason, Fig. 1 shows the X-ray spectroscopy (XPS) spectra of nanorodsand semi-spherical particles of CePO4. This data also include photographs of different ratios of PMMA/PU that showed the transparency of the samples synthesized (Fig. 2). The thermal properties ofPMMA/PU IPNs are confirmed in thermograms of selected PMMA/PU IPNs in Fig. 3. In addition, visualexamination after incorporation of nanostructure in the polymer was analyzed. The incorporation, 0.1,0.5, and 1wt.% of CePO4 (nanorods and semi-spherical) in 50/50 ratio of PMMA/PU IPNs is shown inphotographs (Fig. 5). In this context, dispersion and emission properties of CePO4/PMMA/PU IPNs isconfirmed by confocal laser scanning images showed in Figs. 6 and 7. Dispersion of nanorods andsemi-spherical CePO4 was evaluated in a selected sample, 5O/50 PMMA/PU IPNs (Fig. 8). On the otherhand, the texture of fractures from the tensile test is observed in Fig. 9. Finally, visual inspectionbefore and after accelerated weathering test is seen in Fig. 10.Fig. 2. Photographs of pure PMMA/PU IPNs in different ratios.Fig. 1.

X-Ray photoelectron spectroscopy (XPS) test was assessed in an Alpha 110, ThermoFisher ScientificXPS spectra of CePO4 powders at two different pH are shown in Fig. 1. XPS spectra show typicalbinding energies of Ce3þ and Ce4þ , which are forming the chemical state of as-prepared powders.The results were used to confirm the chemical composition.2.2. Sequential synthesis of PMMA/PU/IPNs and CePO4/PMMA/PU/IPNsIPNs were prepared following the procedure in Ref. [1]. The transparency of the different ratios ofPMMA/PU was evaluated by visual examination of samples synthesized, as it is shown in Fig. 2.Thermal properties of selected PMMA/PU pure samples were evaluated in Differential scanningcalorimetry (DSC), conducted using a simultaneous Labsys Evo, Setaram TGA/DSC. Samples of DSCwere tested at a heating rate of 10 K/min over the temperature range from 30 to 250 °C, undernitrogen atmosphere. Approximately 10–20mg of each sample was placed in aluminium cruciblesand maintained at 30 °C for 2min, heated from 30 °C to 250 °C, maintained again at 250 °C for 2min,Fig. 10.

Ultra-thin sections were microtomed in epoxy resin. Thesample was embedded and cured in R1078 Agar low viscosity resin (Agar scientific). The sample wasshaped into a pyramidal shape and cut with a diamond knife into slices. A slice was put onto a HoleyCarbon film 200 mesh Copper (HC200Cu).
