Abstract: In a composite material contg. 10-97 vol.% aerogel particles and adhesive(s). The dia. of the aerogel particles is less than 0.5 mm. Also claimed is a method of making the composite. Pref. the adhesive is a phenol-, resorcinol-, urea- and/or melamine-HCHO resin. The aerogel is used in a fraction of 40-95 vol.% and has a particle dia. of less than 0.2 mm, esp. with bimodal distribution. It esp. is a SiO2 aerogel, more esp. with permanently hydrophobic gps. on the surface. Its porosity is more than 60% and density less than 0.6 g/cm . The composite may also contain fillers. The composite material has a density of less than 0.6 g/cm and thermal conductivity of less than 100 mW/m.K. It esp. has hydrophobic surface(s).

Abstract: The invention relates to a filter material as well as a process for removing components from gas mixtures and liquids wherein a flow of gas or a liquid is brought into contact with a filter material made of a porous polymer. The porous polymer is formed from homogenous solution by phase inversion. The filter material works selectively and can be used especially for removing ozone, hydrogen peroxide, nitrogen oxides, halogens and organic peroxides from gas flows and liquids.
