Fluorescent Impurity Centers for Monitoring the Physical State of Polymers and a Computer Simulation of Processes of Structuring of the Polymer Matrices

Abstract

The temperature influence and the structure changes of polymer matrix on fluorescence of impurity luminescence centers were investigated. The obtained data broadens the perspectives of using triphenylmethane dye as a detector that helps to analyse physical conditions of polymers. Computer simulation of polymer matrices structuring process was carried out. The results of the calculations by the methods of MM+ and ZINDO/S prove the mechanism of appearance of hysteresis as a change of environing geometry of luminescent centers.
