Abstract

Mixtures of Teflon and powders of metals (magnesium and tungsten) and non-metals (boron and silicon) after their joint mechanochemical activation are analyzed via surface-activated laser desorption/ionization. It is shown that this technique allows determination of the chemistry of surfaces of metals and non-metals, along with the decomposition degree of Teflon. It is established that the oligomeric Teflon degradation products can be registered up to 2500 Da along with low-molecular degradation when analyzing Teflon mixtures with magnesium.
