AB - silica–gelatin composite aerogels with excellent absorption capacity were obtained. The preparation process was as follows: firstly, the gel with stable network structure was formed by sol–gel method; secondly, after soaking the gel with hexamethyldisilazane solution, the aerogel was pre- pared by freeze-drying; finally, the aerogel was coated with hexamethyldisilazane via chemical vapor deposition. The composite aerogels with 30% gelatin showed optimal per- formance in practical applications: lowest bulk density (0.068 g/cm ), highest porosity (96%), largest pore volume (1.24 cm /g), and maximum oil/organic solvents absorption capacity (12–27 g/g). The excellent oil/solvent absorption capacity and recyclability indicated that the hydrophobic gelatin–silica composite aerogels could be a promising candidate for oil absorption. ● ● ● Keywords Gelatin Silica aerogel Composite ● ● Hydrophobic Porous structure Oil absorption Electronic supplementary material The online version of this article 1 Introduction (doi:10.1007/s10971-017-4378-z) contains supplementary material, which is available to authorized users.
