摘要：
The carbon foam-reinforced polyimide (CF-PI) aerogel composites have low shrinkage (as low as 9.25 vol.%).The CF-PI aerogel composites have low thermal conductivity (21 mW m−1 k−1–34 mW m−1 k−1).These aerogel composites also performed well in thermal stability, and did not decompose unless the temperature exceeds 400 °C.Since the foam for reinforcement is three-dimensional and can be cut into any shape as desired, the advantages of these CF-PI aerogel composites not only have shape stability, but also can be customized into specific shapes.
