Entwicklung photosensitiver Polymernetzwerke mit Formgedaechtniseigenschaften

In the present thesis a polymer system with shape-memory properties is developed. The shape-memory effect is triggered by irradiation of the polymer with UV-light with different wavelength. The irradiation causes a reversible change of network density of the elastomer. By that, the elastic properties of the material are changed in a way that the fixing of a temporary shape by UV-irradiation is possible. Irradiation of the fixed sample with another UV-light releases the fixing and the permanent shape of the polymer sample is recovered. The light triggered one-way shape-memory effect for polymers has been realized for the first time.SIGLEAvailable from: http://www.deposit.ddb.de/cgi-bin/dokserv / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekDEGerman
