Abstract:
1. A method for characterizing a scientific material selected from the group consisting of silicate material, a polymer material and a nanomaterial, comprising the following steps: a) irradiating a measuring light of a predetermined wavelength range into a material specimen, b) recording of the measuring light reflected and/or reemitted by the material specimen, c) determining a ratio depending on the wave lengths of irradiated to detected measuring light spectrum, and d) numerical-mathematical processing spectral data of the material specimen to determine at least one characteristic feature of the material specimen selected from particle size, specific surface area, derivatization, pore porosity, pore size and pore diameter and in the case of polymers the characteristic feature may additionally be one of degree of polymerization, molar mass distribution, crystallinity, thermal phase transitions, branching, stereoregularity and tacticity.
