Slobodni volumen u polimernim sustavima

The free volume of polymers plays an important role in the understanding of many characteristic properties such as mechanical and electrical properties and transport of small molecules and gases. The development of new methods in recent years have improved polymer characterization of free volume: the size and the shape of holes and free volume distribution. The paper reviews some of the most frequently used free volume theories and recent results of the applications of probe methods: electron spin resonance, ESR, - spin probe/label method, fluorescence method and positron annihilation spectroscopy, PALS. The scope and limitations of the reviewed methods in the study of free volume are described. The analysis of free volume correlated with the polymer properties offers a possibility to control and improve polymer characteristics during the polymer preparation and processing.
