Abstract As a porous sound-absorbing material, PI aerogel has a poor sound-absorbing performance for low-and medium-frequency sound waves. In order to improve the sound-absorbing performance of PI aerogel to sound waves with low or medium frequency, the present study introduced hollow glass microsphere (HGM) with different particle sizes (29 μm, 40 μm and 55 μm) as a component to prepare HGM/PI aerogel composites with excellent low- and medium-frequency sound-absorbing performance by sol-gel and supercritical CO₂ drying. In this work, the properties (specific surface area, shrinkage and density), microstructure and sound-absorbing performance of the composites were studied, and the effects of particle size and added amount of HGM, and thickness of the composites on the sound-absorbing performance of the composites were analyzed. The results indicate that the density (0.156—0.208 g/cm³) and specific surface area (107.8—399.8 m²/g) of the composites are rela-ted to the stacking density and the added amount of HGM. In the range of 500—6 300 Hz, the peak value of sound-absorbing coefficient of blank sample (PI aerogel) with a thickness of 30 mm is 0.39, corresponding to 3 150 Hz. After introducing HGM component, the composites with the same thickness have peak values within the range of 1 000—2 500 Hz.The positions of peak values shift to the lower-frequency band compared with blank sample and the values are higher than 0.39, ranging from 0.56 to 0.87. According to the comparison of composites composed of HGM with different particle sizes, in the range of 1 000—2 500 Hz, the composite material composed of 29 μm HGM and PI aerogel has the best sound-absorbing performance, while the composite material composed of 40 μm HGM and PI aerogel has the worst sound-absorbing performance. In addition, with the increase of the amount of HGM, the peak value of the sound-absorbing coefficient of the composite material gradually shifts to the lower frequency band, and appears to decrease at first and then increase, and the peak value of the sound-absorbing coefficient shifts to the higher frequency band with the decrease in the material's thickness.
