12.2.3.1 SCANNING ELECTRON MICROSCOPY (SEM)

The state of dispersion of the wood flour in the polymeric matrix was analyzed with SEM. A FEI Quanta 400 microscope (NE Dawson Creek Drive, Hillsboro, Oregon) working at 30 kV was used to obtain microphotographs of the fractured surfaces of the composites. Samples were cut in liquid nitrogen to avoid any deformation of the surfaces.
