The main focus of this work was to establish a good understanding of the reaction kinetics and behavior of hydroxypropyl cellulose during esterification with different acid chlorides, ranging from unsaturated 10-undenoic acid to stearic acid. Once this was well understood and controlled, the materials were used in an effort to crate tailored functional interfaces aiming for the discovery of possible applications and further utility. To this end both, classical surface coating techniques,
