Compositions include an aerogel component and have low thermal conductivity. Methods for preparing slurries or composites include, for example combining the aerogel component with a surfactant, binder and other ingredients, such as, for instance, fibers. The compositions can be slurries that can be used in coating applications or self supporting rigid composites.

The present invention relates to an aerogel composite and a preparation method thereof. The preparation method of the aerogel composite of the present invention comprises the following steps; preparing a hydrophobic gel (step 1); dispersing fiber in a solvent to prepare a solution (step 2); adding the hydrophobic gel above in the solution of step 2 and stirring the mixture to prepare a fiber and hydrophobic gel mixed solution (step 3); separating floc from the mixed solution of step 3 (step 4); and drying the floc (step 5).
