Abstract
Polymeric aerogels, articles made from the polymeric aerogels and methods of making the polymeric aerogels are provided. The aerogels are made e.g. from crosslinkable monomers such as isocyanate monomers or phenolic monomers and a filler comprising crosslinkable hydroxyl groups. The filler may be natural (e.g. wood flour) or synthetic. The aerogels and products made therefrom exhibit low thermal conductivity and are mechanically strong. Due to their physical properties, these materials are used as e.g. building envelope components, such as walls, roofs and frames, to improve the thermal performance thereof, and may be used in a variety of other applications such as sound and insulation barriers in mechanical equipment, cryogenic containers, etc.
