Description
Summary:Hydrophobic silica aerogel composite materials are considered as one of the most promising thermal insulation materials in energy-saving buildings. With the increasing negative effect on the environment of construction waste, it is necessary to develop an effectively recyclable thermal aerogel material for the building industry. In this work, we firstly employed a reversible gelling of hydrophobic silica aerogel microparticles dispersed with methyl cellulose surfactant (MCS) to prepare recyclable thermo-insulating panels (RTIP). The RTIP, with low bulk density (
