Abstract Near-field thermal radiation has received increased attention due to the performance of efficient energy conversion. In this study, the vacuum gap distance between two objects, separated by 1 μm polystyrene particles, is investigated. The entire experimental device is installed in a highly vacuumed environment to ensure that the radiative heat flux dominates the main mode of heat transfer. Compared with the measurement of near-field thermal radiation of flat glasses, it is found that coating SiC film on the hot side of optical glass can reduce heat transfer. However, through theoretical analysis, it is shown that there is an optimal thickness of SiC film of around 1 μm. In addition, the experimental data and theoretical analysis results are consistent. The experiment demonstrates that the regulation of radiative heat flux can be achieved by coating. As the thickness of SiC film on the hot side increases, the radiative heat flux decreases.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
