“…For this reason, it is thought that direct measurements could not be taken from the fiber surface. However, it can be suggested that these resistivity values may be sufficient to provide the antistatic properties to the composites [ 50 , 51 ].…”

This work reports the surface modification of polyacrylonitrile (PAN) fibers by graft copolymerization to ensure the decoration of homogenous and dense Ag nanoparticles. Two facile and subsequent modification processes resulted in a PAN fiber composite with an intact fibrous structure, sufficiently conductive for antistatic application and antibacterial activity. In the first step, some chemically attractive monomers and monomer mixtures, such as acrylic acid (AA), AA-itaconic acid (AA-IA), AA-acrylamide (AA-AAm), were introduced to the fiber surface by grafting. The grafting process was evidenced by FTIR, 1 H-NMR, and SEM techniques. The second step aimed to form a chelate structure by Ag + ions with the coordination centers imparted to the PAN structure, and then, Ag nanoparticles (AgNPs) were decorated on the copolymer fiber surfaces by reducing with the NaBH 4 . The presence, distribution, and changes that occurred after the AgNPs decoration were also monitored by the SEM technique. It was obtained that the AgNPs could not be easily removed from the composites, which presented an appearance as if they were dyed with Ag. It was determined that the composite fibers gained a certain degree of conductivity with the surface resistivity value of 10 9 –10 2 Ω/cm 2 . The antibacterial activity of the composites against E. coli and S. aureus was examined by the zone of inhibition test compared to their detergent-washed samples.

PAN (Polyacrylonitrile)-based carbon nanofibers and microfibers were prepared under the same preoxidation and carbonization conditions, and they were added into fluorocarbon resin as conductor fillers to make antistatic coatings. The electrostatic properties of carbon nanofibers and microfibers were compared by testing the surface resistivity of the coatings filled with different fibers. The carbon contents, bulk resistivities, apparent crystallinities of the different carbonaceous fibers were investigated to analyze the relations between their structure and electrical conductivity. The results show that the carbonization degree of carbon nanofibers is higher than that of the carbon microfibers under the same treatment conditions. The surface resistivity of the coating filled with carbon microfibers is 103∼105 times higher than the one filled with carbon nanofibers with the same filler content. Notably, if filled with carbon nanofibers, the surface resistivity of the coating is adjustable between 104 and 108 Ω. So, carbon nanofibers can fit the different antistatic materials well. Compared with the carbon microfibers, nanofibers is more applicable for preparing antistatic coatings.
