Resumen:
A systematic experimental study of the interface using SEM/EDX is presented. GF were subject to the in-situ polymerization routine explained above, which laboratory details are in [1]. After polymerization, some samples were etched with n- heptane at high temperature for extracting the polymer physically bonded to GF. At this condition it was proved that the entire polymer dissolves into the solvent. Then, if polymer remains onto fibers is chemically bonded. Then, three kinds of samples were analyzed; pure GF, polymerized GF and n-heptane etched polymerized GF, in a JEOL 35 CF equipped with secondary electron detection and X-ray energy dispersive system EDAX DX-4. All samples were previously coated with Au in a sputter coated to make them conductive
