The invention provides a graphene oxide/organic aerogel composite material with a low shrinking percentage. Graphene oxide well penetrates in a matrix of organic aerogel, plays a role of skeleton supporting, and thus inhibits the shrinkage of the organic aerogel. The composite material has a linear shrinkage percentage of as low as 0.5%, a density of as alow as 0.14 g/cm3, and has greatly improved performance when compared with a material before compounding. Meanwhile, the invention also discloses a method for preparing the composite material. |
