Characterization of chemically modified wood fibers using FTIR spectroscopy for biocomposites

Chemical modifications of wood fibers (Lignocel® C120) were performed for biocomposite applications, and chemically modified wood fibers were analyzed by FTIR spectroscopy. NaOH treatment showed band shifts from Cell‐I to Cell‐II in FTIR spectra from 2902 cm−1, 1425 cm−1, 1163 cm−1, 983 cm−1, and 89...

description Chemical modifications of wood fibers (Lignocel® C120) were performed for biocomposite applications, and chemically modified wood fibers were analyzed by FTIR spectroscopy. NaOH treatment showed band shifts from Cell‐I to Cell‐II in FTIR spectra from 2902 cm−1, 1425 cm−1, 1163 cm−1, 983 cm−1, and 897 cm−1 to 2894 cm−1, 1420 cm−1, 1161 cm−1, 993 cm−1, and 895 cm−1 and the change in peak height at 1111 cm−1 and 1059 cm−1 assigned for Cell‐I structure. Silane treatment showed peak changes at 1200 cm−1 assigned as SiOC band, at 765 cm−1 assigned as SiC symmetric stretching bond, at 700 cm−1 assigned as SiOSi symmetric stretching, and at 465 cm−1 assigned as SiOC asymmetric bending. Benzoyl treatment resulted in an increase in the carbonyl stretching absorption at 1723 cm−1 and in band characteristics of aromatic rings (1604 cm−1 and 710 cm−1) and a strong absorption at 1272 cm−1 for CO band in aromatic ring. © 2010 Wiley Periodicals, Inc.
