Epoxy resin (EPR) insulations play a vital role in the insulation of modern power electronic equipment owing to their excellent dielectric properties. However, due to the high-power density and miniaturization of power equipment which causes high heat fluxes under high voltage and high-frequency stresses, EPR with good thermal and insulation properties is urgently needed. In this study, the polydopamine functionalized micro-BN and core-shell nano TiO2–SiO2 particles are dispersed in EPR to simultaneously improve thermal and dielectric insulation properties. It is revealed that the addition of micro-nano particles significantly improves the thermal and dielectric performance. Particularly, the high thermal conductivity of micro-BN and the dielectric barrier effect due to the core-shell structure of nano TiO2–SiO2 are the main reasons for improved thermal and dielectric insulation performance, respectively. The EPR composite containing 3 wt% of micro-BN and 1 wt% of nano TiO2–SiO2 exhibits the optimal performance with 0.49 W/mK thermal conductivity and the highest dielectric strength among all the samples, that is, 60.61 kV/mm even at 10 kHz and 90°C. This study found that the crucial factors are the surface encapsulation, weight percent, and homogeneous dispersion of particles in EPR, the dielectric barrier effect, thermal conductivity, and the mismatch between the dielectric constant of EPR and particles. This study proposes the optimal weight percent of suitable micro-nano particles for EPR to produce suitable composites for high-frequency and high-temperature applications. 相似文献

Sonodynamic therapy (SDT) for cancer treatment is gaining attention owing to its non-invasive property and ultrasound‘s (US) deep tissue penetration ability. In SDT, US activates the sonosensitizer at the target deep-seated tumors to generate reactive oxygen species (ROS), which ultimately damage tumors. However, drawbacks such as insufficient ROS production, aggregation of sonosensitizer, off-target side effects, etc., of the current organic/nanomaterial-based sonosensitizers limit the effectiveness of cancer SDT. Very recently, metal complexes with tunable physiochemical properties (such as sonostability, HOMO to LUMO energy gap, ROS generation ability, aqueous solubility, emission, etc.) have been devised as effective sonosensitizers, which could overcome the limitations of organic/nanomaterial-based sonosensitizers. This concept introduces all the reported metal-based sonosensitizers and delineates the prospects of metal complexes in cancer sonodynamic therapy. This new concept of metal-based sonosensitizer can deliver next-generation cancer drugs. 相似文献
