Abstract

Cellulose films obtained from TISC Langmuir–Blodgett films provide a model system for adsorption studies of dyes and polyelectrolytes. The conversion of multilayers of trimethylsilylcellulose (TMSC), a “hairy-rod” molecule with short hydrophobic TMS side groups, into ultrathin cellulose films, the derivatization of these films with succinic anhydride, and the use of regenerated and modified cellulose films for adsorption studies are reported with the aim of finding ways of changing the chemical properties of cellulose films.
