Synthesis of Hydrophobic Aerogel Heat Insulation Materials Based on Polyvinyl Alcohol/Carbon Black Composite

Abstract

Modification of the composition of polyvinyl alcohol/carbon black aerogel composite materials was performed to make them hydrophobic. The physicochemical properties of the matrices obtained, including their thermal conductivity and resistance to aggressive media and water, were studied. Materials with the moisture capacity decreased by up to 96%, exhibiting resistance to aggressive organic media and high heat insulation properties, were obtained.
