Nanocompuestos con base polimérica resistente a impactos
Abstract
Con el objetivo de determinar las propiedades mecánicas y de impacto a nanocompuestos de polipropileno con nanotubos de carbono multipared al 1, 3 y 5 %, se le realizaron estudios morfológicos con el Microscópico Electrónico de Barrido, obteniendo micrografías con una dispersión uniforme de los nanotubos en la matriz polimérica. Además, mediante la técnica de Análisis Dinámico Mecánico y los ensayos Izod y de Tracción, se observó de manera general, que a medida que se aumenta el contenido de los nanotubos, las propiedades mecánicas se incrementan con respecto a la matriz polimérica, lo que demuestra el efecto de reforzamiento. Por otra parte, se ve reflejado el aumento del módulo de almacenamiento dinámico, indicando un incremento de la rigidez. De acuerdo con los resultados obtenidos, se concluye que los nanocompuestos obtenidos son más ligeros y resistentes frente a colisiones e impactos, los cuales pueden ser empleados en diferentes sectores de la industria.
Palabras clave: nanocompuestos, nanotubos de carbono, impacto, resistentes.
