Fig. 4 corresponds to the TEM images of the samples for different magnifications and regions. Fig. 4(a) corresponds to the sample with 0.5 mmol L−1 of AgNO3. This figure reveals that particles are well dispersed with a diameter from 2 up to 15 nm. Fig. 4(b) shows the particles produced for the sample with an AgNO3 content of 2 mmol L−1. It can be noted that a large amount of small monodisperse particles with a diameter of about 2 nm were formed. It can also be seen that larger particles (a diameter of 40 nm) were produced probably by the diffusion of the small particles to the edge of the latex films, causing an increase in the size of particles due to aggregation. The large agglomerate observed in Fig. 4(c) is related to the sample with 4 mmol L−1 of AgNO3. By increasing the magnification in that same region, it could be observed that the agglomerate is formed by many smaller silver particles (Fig. 4(d)). It is also possible to note from Fig. 4(d) that the diameter sizes of the particles are smaller than 100 nm. From the inset of Fig. 4(e), one may realize that the silver particles possess diameters ranging from 20 to 86 nm with a mean diameter size of around 50 nm. In addition, Fig. 4(f) shows another region where the formation of small silver nanoparticles with a diameter smaller than 100 nm is evident.
