摘要

通过600、800和1000℃的固相反应制备了钙钛矿La2Ti2O7:Fe2O3室温固化环氧复合材料，并测定了其紫外吸收特性。由于La2Ti2O7:Fe2O3着色剂具有可调谐的光学带隙特性，因此进一步研究了环氧复合材料的介电性能。研究结果表明，环氧树脂增强的La2Ti2O7:Fe2O3陶瓷复合结构在适当的纳米填料负载下具有较好的介电特性。此外，与纯环氧复合材料和裸环氧复合材料相比，La2Ti2O7:Fe2O3增强环氧复合材料在更高的温度下发生完全崩解。

Thermal and dielectric characterization of epoxy reinforced Fe2O3-La2Ti2O7 based ceramic nanocomposites: A scientific intervention for optoelectronic applications

The room temperature cured epoxy composites of perovskite La₂Ti₂O₇:Fe₂O₃ were developed via solid state reaction at 600, 800 and 1000 °C and their UV absorption characteristics were ascertained. Further the dielectric properties of the epoxy composites were studied since the La₂Ti₂O₇:Fe₂O₃ colorants have demonstrated tuneable optical band gap properties. The findings of the investigation suggested that the epoxy reinforced La₂Ti₂O₇:Fe₂O₃ ceramic composite structures have improved dielectric characteristics at modest loadings of nanofiller. Additionally, the complete disintegration La₂Ti₂O₇:Fe₂O₃ reinforced epoxy composite was found to occur at a higher temperature when compared to that of neat and bare epoxy composites.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
