3.4. SEMwithEDXanalysis
SEM was performed in order to investigate morphology of the polymers and the composites. EDAX was done to reveal the chemical composition of the samples. Fig. 4(a)–(c) shows the SEM images of PT, -CuPT and n-CuPT. The EDX spectra of PT, -CuPT and n-CuPT is shown in Fig. 5(a)–(c). The elements present in the PT, -CuPT and n-CuPT with weight percentage are shown in the Table 1, 2 and 3. The EDX result in shows that micro and nano copper was present in the composite with a weight percentage of 45 and 50%. The SEM images of PT exhibits clusters of the spherical shaped nano polymers which are revealed in Fig. 4(a). The SEM micrographs of PT reveals uneven distribution of particles. It also shows that PT chains are loosely packed. This indicates that PT is amorphous in nature. The nano composites exhibit more uniformity distribution of
