Summary: As flexible electronic devices become smaller and more powerful, the need for efficient thermal management becomes crucial due to the increased heat generation. However, the low thermal conductivity of flexible substrates poses a challenge for effective heat dissipation. This study successfully fabricated large-area flexible films using electrospinning technique, demonstrating notable thermal conductivity of up to 38.4 Wm-1K-1. At a filler concentration of 50 wt%, the film showed superior performance with a thermal conductivity of 28.6 Wm-1K-1, a tensile strength of 27.8 MPa, and an elongation of 8.1%. Furthermore, the film exhibited exceptional flexibility, meeting the requirements for next-generation flexible substrates.

Summary: In this study, we reported on the structural and photoluminescence properties of porous silicon carbide formed by electro-chemical etching of SiC plate. The photoluminescence spectrum in the visible region was observed and could be fitted with at least three peaks, with the properties discussed in relation to SEM, TEM, and Raman studies. The nature of the peaks were explained by electron-hole recombination, surface defect centers, and SiC nanocrystallites.
