Resumen
Se produjeron microfibras de bagazo de caña de azúcar que exhiben repelencia al agua tras su pretratamiento y modificación superficial con hexadeciltrimetoxisilano. Fueron estudiados tres pretratamientos para llevar a cabo deslignificación, remoción de hemicelulosa y exposición superficial de celulosa: tratamiento con hipoclorito 3% (HP), mezcla clorito de sodio y ácido acético (CAc) y una solución oxidante de hipoclorito-peróxido de hidrógeno seguida de tratamiento alkalino (OX-B). Lignina y hemicelulosa fueron efectivamente removidas de las fibras de bagazo con el tratamiento OX-B, el cual produjo fibras desagregadas de 567 ± 115 μm de largo y relación de aspecto de 32. Otros tratamientos como el HP producen menor cantidad de fibras, con menor longitud, 296 ± 32. La efectividad del tratamiento seleccionado, OX-B, permitió obtener un material lignocelulósico a partir de bagazo de caña de azúcar, fácilmente modificable e impermeable al agua cuyas características suponen su efectividad como elemento de reforzamiento en materiales compuestos de matriz polimérica.
