Abstract
In the present manuscript our aim has been to modify the surface of mercerized lignocellulosic Grewia optiva fiber through silane treatment using Aminopropyltriethoxysilane (APS) as coupling agent. Prior to silane treatment parameters like time and NaOH concentration for mercerization were optimized. Cellulosic fibers treated with different APS concentration solution were then subjected to evaluation of some of their properties like swelling, moisture absorbance and chemical resistance behavior against acid and base solutions. Lignocellulosic fibers treated with 3 % APS solution have been found more resistant towards moisture, water and acid and base solutions. Morphological structural changes, thermal stability and crystallinity of both silane and alkali treated fibers have been studied using SEM, FTIR, TGA and XRD techniques. It has been observed that crystallinity of the raw fiber increased after the mercerization but decreased little bit after the silane treatment. However, APS treatment results in increased thermal stability as compared to alkali treated and raw lignocellulosic fiber.
