Abstract Banana fibers obtained from the sheath of the banana plant (<I>Musa </I><I>Sapientum</I>) whose major constituent is cellulosewere modified using various chemical agents in order to improve their compatibility with the polymer matrix.The change in the surface composition of the raw and chemically modified fiber was investigated using varioustechniques such as solvatochromism, electrokinetic measurements, and XPS. Surface characterization by XPSshowed the presence of numerous elements on the surface of the fiber. Investigation of the surface after alkalitreatment on the other hand showed the removal of most of the elements. Silane treatment was found to introducea considerable amount of silicon on the surface of the fiber. The [O]/[C] ratio was found to decrease in all casesexcept for the fluorinated and vinyl silane treated fibers. Detailed investigation of the deconvoluted C 1s spectrarevealed the change in the percentage atomic concentration of the various elements on the fiber surface. Thedissolution of the various surface components by alkali treatment, which was earlier revealed by SEM, was furtherconfirmed by XPS. The XPS results were found to perfectly agree with the solvatochromic and electrokineticmeasurements.
