PURPOSE: To obtain the subject fibers with specific oxygen-contg. functional groups on the fiber surface, capable of giving composite materials having excellent high-frequency characteristics, mechanical strength and durability and also usable in ICs or the like through composite formation with matrix resins.
CONSTITUTION: The fluorocarbon fibers are obtained by incorporating the fluorocarbon fiber surface with oxygen-contg. functional groups bound to the fiber-forming polymeric molecular chains pref. by low-temperature plasma treatment. In the above fibers, it is preferable that, for the oxygen-contg. functional groups, the atom number ratio O1s/C1s (the number of moles of oxygen atoms per mol of carbon atom) in terms of ESCA measurements is ≥0.02 higher than that inside the fiber (at least ≥0.5 μm in depth from the fiber surface).
