As an organic solid catalysis, blend films of chitosan or PEG-Chitosan derivative with PVB were prepared. The palladium adsorption ability of the blend films depended on the blend ratio (chitosan contents). The surface condition of Chitosan⁄PVB blend film was rough as a result of phase separation while that of PEG-Chitosan⁄PVB blend film was flat and homogeneity.
