Development of new composites materials, carriers of active agents, from biodegradable polymers and wood

This work consists in the preparation of a biodegradable system starting from wood and polymer; this system being a support for the release of active agents. These starting materials used are poly(ε-caprolactone) (PCL), wood, the active agent being KCl. Initially the influence of water, wood and KCl on the reaction of polymerisation is studied. Two kinds of release systems are carried out: wood samples impregnated with KCl and/or PCL and blends of PCL, wood and KCl. Lastly, the release of KCl from these systems is studied in water. .
