However, the improved properties of diamond-polymer composites depend on the size, dispersibility, and concentration of diamond particles. In the present study, diamond-polymer composites were prepared by adding the microdiamond particles (MDPs) with different concentrations (0.2-1 wt.%) into polymers (acrylate resins) and then subjected to a photocuring process. The surface morphology and topography of the MDPs-polymer composites demonstrated a uniform high-density distribution of MDPs for one wt.% MPDs. Thermogravimetric analysis was employed to investigate the thermal stability of the MDPs-polymer composites. The addition of MDPs has significantly influenced the polymers' thermal degradation. Absorption and emission spectra of thin layers were recorded through UV/Vis spectrophotometry and spectrofluorimetry. The obtained results revealed a significant increase in the fluorescence intensity of MDPs-polymer composites (at 1 wt.% of MDPs, a 1.5×, 2×, and 5× increase in fluorescence was observed for MDPs-green, MDPs-amber daylight, and MDPs-red resin, respectively) compared with the reference polymer resins. The obtained results of this work show the new pathways in producing effective and active 3D-printed optical elements.Nanomaterials (Basel, Switzerland)Tailoring of Optical Properties of Methacrylate Resins Enriched by HPHT Microdiamond Particles.PMC9370547POIR.04.04.00-00-1644/18Ficek MFormela KKunuku SZielinski ASawczak MKowalewska EBogdanowicz RfalseTailoring of Optical Properties of Methacrylate Resins Enriched by HPHT Microdiamond Particles.Diamond particles have great potential to enhance the mechanical, optical, and thermal properties of diamond-polymer composites.
