Abstract

In this study, TiO₂ nanosheets were directly grown on ZrO₂ fibers by employing a solvothermal technique without requiring a TiO₂ seed layer, targeting thermal radiation shielding applications. The crystalline form and microstructure of the TiO₂ nanosheets were characterized using SEM, Raman, XRD, XPS, and TEM. The infrared thermal radiation extinction properties of the TiO₂ nanosheets were evaluated using DRS and effective specific extinction coefficient (e*), and their thermal endurance at high temperatures was also assessed. The results showed that, within the infrared band of 2.5 to 8.5 μm, the TiO₂ nanosheet arrays with a thickness of 423 nm enhanced the e* of ZrO₂ fibers by 58.59 %. At similar coating thicknesses, nanosheet coatings exhibited superior thermal radiation shielding performance compared to nanoparticle coatings. These findings suggest that ZrO₂ fibers loaded with TiO₂ nanosheets are promising candidates for thermal radiation shielding in aerogels or extreme environmental conditions.

期刊介绍： Materials Characterization features original articles and state-of-the-art reviews on theoretical and practical aspects of the structure and behaviour of materials. The Journal focuses on all characterization techniques, including all forms of microscopy (light, electron, acoustic, etc.,) and analysis (especially microanalysis and surface analytical techniques). Developments in both this wide range of techniques and their application to the quantification of the microstructure of materials are essential facets of the Journal. The Journal provides the Materials Scientist/Engineer with up-to-date information on many types of materials with an underlying theme of explaining the behavior of materials using novel approaches. Materials covered by the journal include: Metals & Alloys Ceramics Nanomaterials Biomedical materials Optical materials Composites Natural Materials.
