Abstract

Monitoring and counting of the fine particles released during the temperature rise of the resorcinol-formaldehyde polymer suitable for conversion to carbon aerogel are discussed in the poster. Carbon aerogel is produced by heat treatment under inert atmosphere. The presented approach combines the thermogravimetric analysis with detailed monitoring of the size distribution of fine particles produced. Thermogravimetric analysis (TGA) allows the exact temperature influence of the sample and identifies its weight loss. Aerosol stream leaving TGA enters a Scanning Mobility Particle Sizer (SMPS) where the particle size fractions are separated. A number of particles in the particles size fractions are identified by the condensation particle counter (CPC). Long-term use of Carbon Aerogels results in degradation of these materials and release of fine particles, which could be harmful to health.
