Grupo de Materiales Compuestos y Mezclas Poliméricas: lineas de investigación:

Microplásticos: se estudia la distribución espacial en la cuenca del arroyo Langueyú, fuentes de microplásticos, variación temporal, transporte y medidas de mitigación.

Compuestos de matriz polimérica, con diferente tipo de carga, y mezclas poliméricas que incluyen polímeros biodegradables. Particularmente se analizan fenómenos de interfase e influencia de la carga sobre las propiedades termomecánicas en compuestos de matriz epoxi cargado con partículas de aluminio, cuarzo o cobre. En mezclas poliméricas se estudian fenómenos asociados al desarrollo de cristalinidad y segregación de fases en PHB/DGEBA y PHB/Epoxy.

Aleaciones base Cu y Al se estudian desde el punto de vista de su uso como carga o, en forma general, aplicando técnicas de estudio disponibles en el grupo. Desde la perspectiva experimental se aplican técnicas de Dispersión de Radiación X de bajo ángulo (SAXS), Excitación por impulso (IET), Espectroscopía Raman, Calorimetría Diferencial de Barrido, entre otras.
