Ukrainian Journal of Physics| Резюме: | Pure and doped with xanthene dyes Rhodamine 6G and Rhodamine B polyurethane materials were exposed to intense radiation and tested by means of IR spectroscopy. The sensitizing effect of the dyes on photodestructive processes in the polymers was shown, and it was more pronounced in the case of Rhodamine 6G. According to the results of thermogravimetric analysis, the incorporated dyes caused insignificant changes in the thermal stability of polyurethane. The triplex construction of samples was proved to be an effective protection of the polymer films from the action of atmospheric oxygen. |
