Preparation and Hydrophobic Properties of Polyborosilazane Aerogels <i>via</i> CO<sub>2</sub> Supercritical Drying

The polyborosilazane aerogels were prepared by hydrosilylation reaction using polyborosilazane as raw material with divinylbenzeneas crosslinking agent, and then dried by CO<sub>2</sub> supercritical drying. Infrared spectroscopy, scanning electron microscopy, specific surface area and a...
