Figure 9
The image contains two scanning electron microscopy images labeled as P L A m S C G 5 on the left and P L A S C G A 5 on the right. The left image, taken at 125 times magnification, displays the surface of P L A m S C G 5 with a rough texture and scattered irregular structures. A scale bar at the bottom indicates a measurement of 10 micrometers. The right image, captured at 770 times magnification, shows the surface of P L A S C G A 5 with a more complex and textured morphology, differing visibly from the left image. A scale bar of 20 micrometers is present. These images compare the microstructural differences between the two P L A based materials.SEM images of MEX-produced specimens
