Tesis doctoral de Mohammed Musthafa Kummali — <\/strong><\/h2>\n

El objetivo de este trabajo de tesis consiste en desarrollar y analizar t\u00e9cnicas basadas en microscop\u00eda de fuerza at\u00f3mica (afm) para la caracterizaci\u00f3n mec\u00e1nica y diel\u00e9ctrica de materiales polim\u00e9ricos. Para ello, se utiliz\u00f3 nanoespectroscop\u00eda diel\u00e9ctrica (nds) y nanoimaging diel\u00e9ctrico (ndi) para estudiar la din\u00e1mica de pol\u00edmeros en diferentes condiciones. Estas t\u00e9cnicas, recientemente desarrolladas, se emplearon en el estudio de sistemas polim\u00e9ricos con propiedades diel\u00e9ctricas complejas, en conjunto con otras t\u00e9cnicas de caracterizaci\u00f3n macrosc\u00f3picas tales como calorimetr\u00eda diferencial de barrido (dsc) y la espectroscopia diel\u00e9ctrica de banda ancha (bds). En la mayor\u00eda de los casos, adem\u00e1s de la caracterizaci\u00f3n diel\u00e9ctrica a nanoescala, tambi\u00e9n se realiz\u00f3 una caracterizaci\u00f3n mec\u00e1nica utilizando t\u00e9cnicas de afm. La aplicaci\u00f3n de t\u00e9cnicas diel\u00e9ctricas a nanoescala incluye el estudio del nivel de compatibilidad en films delgados de mezclas de poliestireno-polivinilacetato (ps\/pvac) con diferentes tratamientos t\u00e9rmicos. A este respecto, se encontr\u00f3 que dichos pol\u00edmeros son incompatibles, y que su incompatibilidad se incrementa conforme la temperatura del tratamiento t\u00e9rmico aumenta. Estas t\u00e9cnicas fueron tambi\u00e9n aplicadas al estudio de la estructura y din\u00e1mica de cauchos sint\u00e9ticos estireno-butadieno-caucho (sbr) reforzados con nanopart\u00edculas de silica. La caracterizaci\u00f3n mec\u00e1nica a nanoescala revel\u00f3 la presencia de una capa fina de pol\u00edmero sobre las part\u00edculas, que, sin embargo, presenta la misma din\u00e1mica que el resto del material polim\u00e9rico debido a una uni\u00f3n flexible con las part\u00edculas. Finalmente, se estudi\u00f3 el origen estructural de la relajaci\u00f3n diel\u00e9ctrica en copol\u00edmeros polietileno-polivinilacetato (eva) semicristalinos. En este caso, el comportamiento diel\u00e9ctrico de los materiales en bulk fue modelado exitosamente combinado bds y ndi. Estos estudios muestran que las t\u00e9cnicas nanodiel\u00e9ctricas son una poderosa herramienta en el dise\u00f1o y caracterizaci\u00f3n de nanocompuestos polim\u00e9ricos.<\/p>\n
