Wood Polymer Composites (WPCs) based on polypropylene (PP) have gained increasing
interest over the past two decades, both in the scientific community and in industry. Meanwhile, a
large number of publications is available, but yet the actual market penetration of such materials is
rather limited. This paper aims to study an alternative method for compatibilization of wood with
polypropylene, by using an innovative class of environmental-friendly additives, namely ionic liquids.
To emphasize the performance characteristics of the various obtained composite materials
bearing different wood to polymer ratios, water absorption, tensile mechanical tests, surface energy
tests have been performed, indicating a good compatibility between the ionic liquid-additivated wood
and the thermoplastic polymer
