“…15,16 Importantly, PFA is compatible with many organic polymers and inorganic materials, and it gives high carbon yield when pyrolyzing. Compared with other polymers, PFA is important not only for the use as adhesives and binders but also widely used to synthesize nanoporous carbons, glassy carbons, and polymer nanocomposites for a wide range of applications, such as adsorbents, separation membranes, and catalysts 17,18 ; moreover, the use of PFA as lubricating materials is rarely reported, so it is imperative to study the tribological properties of PFA composites. Therefore, in this article, PFA is used as the polymer matrix, however, how to select the proper modified method to obtain the uniform dispersion of MWNTs in matrix is important.…”
