Quasielastische Lichtstreuung von gequollenen Siliconnetzwerken

Abstract: Mit der quasielastischen Lichtstreuung wurden von verschiedenen polymeren Netzwerken (PB, PDMS, PDMSM) im Zustand der Gleichgewichtsquellung kooperative Diffusionskoeffizienten D, gemessen. D, ist eine Funktion der Molmasse der Netzwerkketten und des Gleichgewichtsquellungsgrades, die durch die scaling-Theorie beschreibbar ist. Die hydrodynamischen Radien sind vom Aufbau der Netzketten abhangig. Ein Solanteil im Netzwerk beeinfluat die Form der gemessenen Autokorrelationsfunktion. Die Existenz einer langsamen … Show more

“…Depending on the particle size and the difference between the refractive index of the particle and that of the surrounding medium, the diffraction or scattering pattern is significantly different and characterizable. In the past, light, neutron and X-ray scattering methods have been extensively cited in other works where the structure and dynamics of particles and macromolecules in multicomponent systems are investigated [ 13 , 25 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ].…”
