Abstract

En este trabajo, se aislaron microfibrilllas de celulosa (MFC) del raquis de banano empleando tratamiento químico con hidróxido de potasio al 5%. Estas fueron usadas como reforzantes del polipropileno, para elaborar nanocomposites por mezclado en vía líquida y compresión en caliente. Las microfibrillas fueron caracterizadas empleando espectroscopia infrarroja por transformada de Fourier (FTIR) y análisis termogravimetrico (TGA). Empleando microscopía de fuerza atómica (AFM) se ha establecido que los diámetros de las microfibrillas se encuentran entre 5 – 10 nm, los ensayos de tracción de los nanocomposites desarrollados reflejan incrementos en el desempeño mecánico debidos a la presencia de las microfibrillas aisladas.
