Results of SEM, AFM and XRD examina- tions indicate that Ag coating on the glass fiber has good overall properties with well uniform appearance. In comparison with the conventional electroless plating method, the present approach is novel and facile. After the oxygen plasma treatment of glass fibers, multiple active hydroxyl groups on its surface exhibit strong adsorption capacity to Ag. The coating thickness coul
