Studying the Fabrication and Characterization of Polymer Composites Reinforced with Waste Eggshell Powder

Figure 3

SEM images of PA/ES composite powders: (a) PA3 (the insert image shows the surface morphology of ES and PA particles); (b) PA5; and (c) PA10 (the insert image shows the physical interaction between ES and PA particles). Circles in (a) show less particle distribution of ES within the matrix. Circles in (c) show some agglomerated ES within the matrix. Circles in the insert micrographs of (b) and (c) show the fine ES were dispersed and distributed on the surface of a PA particle.
