Люминесцентные примесные центры для мониторинга физического состояния полимеров и компьютерное моделирование процессов структурирования полимерных пленок

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.

Исследовано влияние температуры и изменения структуры полимерной матрицы на флуоресценцию примесных центров свечения. Полученные данные открывают перспективы применения трифенилметановых красителей в качестве датчиков, позволяющих анализировать физические состояния полимеров. Проведено компьютерное моделирование процессов структурирования полимерных матриц. Результаты расчетов методами ММ+ и ZINDO/S подтверждают механизм появления гистерезиса как изменение геометрии окружения центров свечения.
