Abstract

original image

The cover image shows nanocomposite films developed by Barbara A. Keating et al. on page 2352, in which a galactomannan (guar) matrix is reinforced with cellulose nanowhiskers and plasticised using sorbitol. These cellulose nanowhiskers (CNWs) are rod-shaped particles with varying dimensions and an aspect ratio that depends on the cellulose source. They form stable aqueous colloidal suspensions due to the presence of negative charges on their surfaces. When examined by SEM, the nanocomposite film samples show good distribution of the CNWs within the matrix of the films.
