Physical properties of CNF aerogels.
Photographs of an as-prepared CNF aerogel (mass = 56.1 mg) with a size of 3.1 × 1.7 × 1 cm3 (a) standing on a dandelion and (b) supporting 500 g (ca. 9000 times its weight). (c) The compressive strain–stress curve of a CNF aerogel; the inset shows the photographs of the CNF aerogel before and after the compressive test. (d) The measurement of contact angle with water (top) and soybean oil (bottom) for CNF aerogel.
