Surface properties of in situ organo-montmorillonite modified wood flour and the influence on mechanical properties of composites with polypropylene

- Capillary rise method was used to test contact angles of WF.
- Surface free energies of WFs increased with increasing OMMT concentration.
- Wettability of WF with PP was relative to the dispersive component fraction.
- Mechanical property of WF/PP composites was partly influenced by surface wetting.
