  • Figure 1. Transmission Electron photomicrograph of ginger and PMMA powder showing; a) Ginger’s irregular particle shape distribution of globular and spindle forms; b) ginger particles’ tendency for cluster formation; c) ginger powder particle size distribution; d) PMMA spherical multimodal particle size distribution; e) PMMA cluster of nano-sized spherical particles; f) PMMA discrete particle
  • Figure 2. a) Scanning electron photomicrograph of control PMMA heat cured resin showing polymer matrix; b) higher magnification showing interconnected polymer matrix
  • Figure 3. a) Scanning electron photomicrographs of group (II) resin modified with 3 wt% ginger powder showing thinned resin matrix separated with large intervening spaces; b) higher magnification of group (II) showing dispersed spheroidal particles of different sizes; c) Scanning electron photomicrograph of group (III) resin modified with 5 wt% ginger powder showing thinned irregular resin matrix; d) higher magnification of group (III) showing dispersed spheroidal and spindle shaped particles
  • Figure 4. a) Scanning electron photomicrograph of group (IV) resin modified with 3 v/v% ginger oil showing compacted resin matrix with little spaces and minute scattered particles; b) higher magnification of group (IV) showing condensed resin matrix with many dispersed particles; c) Scanning electron photomicrograph of group (V) resin modified with 5 v/v% ginger oil showing compacted resin matrix in globular like form; d) higher magnification of group (V) showing thick connected globular resin matrix with some spaces
  • Figure 5. a) Scanning electron photomicrograph of group (VI) resin modified with 3wt% powder and 5 v/v% oil showing spherical and irregular shaped particles of different sizes scattered over the resin matrix; b) higher magnification of group (VI) showing resin matrix with spherical and globular shaped particles of different sizes; c) Scanning electron photomicrograph of group (VII) resin modified with 5wt% powder and 3 v/v% oil showing large spheroidal particles embedded in a woven matrix; d) higher magnification of group (VII) showing thinned matrix with large intervening spaces
