Abstract To explore the relationship between the calcination temperature and the thermal insulation performance of the fiber membrane, this study used tetraethyl orthosilicate (TEOS) and polyvinylpyrrolidone (PVP) as raw materials to prepare SiO₂ micro-nano fiber membranes through electrospinning in combination with a follow-up heat treatment. Thermogravimetric and differential thermal analysis, X-ray diffractometer, Fourier infrared spectrometer, scanning electron microscope and thermal conductivity meter were applied to study the thermal decomposition process of SiO₂/PVP hybrid fiber membranes and the influences of calcination temperature on the products' phase composition, micromorphology and thermal insulation performance. The results showed that the products were all amorphous SiO₂ after they were calcinated at 600 ℃ or above. As heat treatment temperature rose, amorphous SiO₂ showed a tendency to transform into crystalline state, and the average fiber diameter decreased before increasing. The products' thermal conductivity was positively related to fiber diameter.When the heat treatment temperature was 800 ℃, SiO₂ micro-nano fibers had the smallest average diameter and the lowest thermal conductivity (0.032 5 W/(m·K)), the thermal insulation performance of which is better than that of the sample at heat treatment temperatures of 600 ℃ and 1 000 ℃ and traditional quartz fiber insulation felt. This experiment provides a substantial experimental basis for optimizing the thermal insulation performance of SiO₂ fiber membrane.
