▎ 摘　　要

NOVELTY - Preparing graphene aerogel comprises placing a macro material formed by stacking and assembling graphene oxide layers in a polar solution containing a foaming agent for plastic foaming and drying to obtain the graphene porous aerogel material. USE - The aerogel is useful in sound insulation, heat insulation, damping, adsorption and electromagnetic shielding (claimed). ADVANTAGE - The aerogel: has strong operability and is easy to implement, without the need for complicated instruments e.g. freeze dryers or supercritical dryers, which is conducive to the industrialization of aerogel materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene aerogel prepared by the above method.
