Modelado por deposición fundida de polipropileno isotáctico reforzado con nanotubos de titanio (TiNTs).
Resumen
En este trabajo se evaluó el rendimiento de refuerzo de nanotubos de Titania en una matriz de polipropileno isotáctico (iPP). Este refuerzo se añadió al 1,0 y 1,5% en peso en la matriz de polipropileno. Para verificar la formación de la estructura tubular, se realizó un análisis FT-IR, mostrando la presencia de las bandas 912 y 647 cm−1 que corresponden a la región de frecuencia del esqueleto del nanotubo de Titania. Se fabricó un filamento de los nanocompositos para la impresión de probetas mediante FDM con ayuda de una impresora Ender 3 Pro. Las propiedades termo-mecánicas se caracterizaron mediante análisis mecánico dinámico (DMA) donde, para los compositos 1,0 y 1,5% en peso. El módulo de almacenamiento (E') fue superior en comparación con el iPP puro, mostrando una mejoría del (40% y 60%) respectivamente.
