| titleOfInvention | Preparation method of composite aerogel with high mechanical strength |
| abstract | The invention discloses a preparation method of a composite aerogel with high mechanical strength. The invention adopts one-dimensional nano-cellulose and two-dimensional graphene oxide to provide a skeleton structure, and improves the mechanical strength of the composite aerogel through the action of hydrogen bonds and gelatin molecules. The dialdehyde crosslinking agent is adopted to carry out chemical crosslinking with the nano-cellulose and the gelatin to respectively generate acetal and Schiff base to form a three-dimensional network structure, the mechanical strength of the composite aerogel is further improved, and the maximum specific compression modulus reaches 2.5MPa cm 3 (ii) in terms of/g. The used raw materials are non-toxic and harmless, are biodegradable, have simple preparation process, and meet the requirements of economy and environmental protection. The prepared composite aerogel has wide application in the aspects of heat insulation materials, energy-saving materials, sound insulation materials, adsorbents and the like. |
