Abstract

Se caracterizaron siete muestras de arcillas bentoníticas colombianas mediante diferentes técnicas como análisis químico, DRX, CIC, TGA, IR, seleccionando la muestra de mayor pureza para ser empleada en la preparación del nanocompuesto. La bentonita seleccionada se modificó orgánicamente con hexadecilamina y el producto se analizó mediante DRX, IR, TGA y DSC, confirmándose la efectividad del tratamiento. La mejor dosificación se estableció en un 33% peso, lográndose el mayor espaciamiento interlaminar y un carácter organofílico apropiado para su compatibilidad con el polímero. Los nanocompuestos fueron preparados por fusión y mezclado en una extrusora utilizando PET reciclado con cantidades variables de arcilla natural y modificada, y sometidos a ensayos mecánicos y análisis físicoquímicos.
