| Abstract: | X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) spectroscopy techniques were used to study the
surface chemical compositions of cellulosic fibers before and after treatments. The fibers were treated with phthalic anhydride
and maleated polypropylene for surface modifications. Both XPS and FTIR spectroscopy analysis indicated that chemical bonds
between hydroxyl groups of cellulosic fibers and anhydride moieties of phthalic anhydride and maleated polypropylene have
occurred through esterification reaction. These chemical reagents have been added to the surface of cellulosic fibers in the
form of monoester, i.e., the formation of esterified cellulosic fibers bearing a pendent carboxylic group.
