Abstract

To investigate the effect of heat treatment on sizing development and the surface chemical states of sizing agents, alkylketene dimer (AKD)/23MC and ketone/23MC (0.3/99.7, w/w) blend films, as a model of sized papers, were heated and used for the x-ray photoelectron spectroscopy (XPS) and water contact angle measurement. Hydrophobicity of the film and concentration of the alkyl chains at the surface of the films were increased with heating times. On the XPS analysis of AKD/23MC and ketone/23MC blend films, ketone/23MC blend films had much more distribution of alkyl chains on its surface than that of AKD/23MC blend films. The hydrophobicity of the films was closely related to the chemical states of sizing agents at the surface. Increase in concentration of alkyl chains seems to be caused the migration of sizing agent to film surface and its molecular orientation at the blend film surface.
