Scanning electron microscopy and transmission electron microscopy were used to observe and analyze the distribution of nanoparticles and the structure of the PTFE matrix in the composites
Through image processing and calculation methods, the distribution density and size distribution of nanoparticles in the composite, as well as the grain size and crystallinity of the PTFE matrix, were quantitatively analyzed
The results showed that the nanopar
