| Description
| - Příspěvek sumarizuje současný stav a aktuální poznatky týkající se oxidační odolnosti polymerů a její stanovování chemiluminiscenční metodou s důrazem na možnosti praktického použití metody v technické praxi. Jsou zmíněny důvody oxidační degradace včetně možných oxidačních schémat, diskutován je původ světelné emise z polymerů a samotná měřící technika včetně nejnovější obrazové CL metody umožňující i vizualizaci světelné emise. Zmíněny jsou doposud zkoumané materiály, důvody jejich výzkumu a nutné podmínky měření. Nechybí ani některé další důležité aspekty z hlediska CL a oxidace polymerů. (cs)
- Polymers belong to the large-scale used materials. There is a necessity to determinate their oxidative stability, because of their degradation due to reaction with atmospheric oxygen. This leads to chemical changes and, consecutively, to deterioration of physical and also aesthetical properties. The chemiluminescence (CL) method is based on measurement of light emitted from polymers caused by their oxidation. Elevated temperature is used as an acceleration factor of degradation. Higher temperature means higher CL intensity and faster degradation. Even thought the CL phenomenon is known already more than 40 years, till now it was not possible to measure it effectively, due to low instrumental sensitivity, because the quantum yield of light is very low, generally on the level of a single photon. The newest trend is so called imaging CL method, utilizing CCD technology. It permits not only photon counting, but also monitoring of the spatial distribution of luminescence. CL experiments are usually carried
