【Abstract】 Macromolecule materials, widely used in electronics industry, unfortunately lack electromagnetic shielding capability; electroless plating can be used to remedy this lack. Glass fiber is frequently used as filler of macromolecule materials. Our aim is to study the processing parameters of electroless plating of Ni-Fe-P alloy on surface of glass fiber; there is, to our best knowledge, no paper on such processing parameters in the open literature; Fe is commonly acknowledged to be effective in enhancing electromagnetic shielding capability, but such use of Fe has not been, to our best knowledge, reported in the open literature. In our experimental study, we pretreated the glass fiber through the cleaning process, the coarsening process, activating process and so on. In this paper we present some methods for measuring and analyzing the properties of the glass fiber electrolessly plated with Ni-Fe-P alloy. In this paper, we mainly discuss the effects of main factors on the properties: （1） the effects of the main factors on the electroless depositing rate, such as the various complex ratios and the concentrations of NiSO₄, FeSO₄ and NaH₂PO₂; （2） the effects of the concentrations of NiSO₄, FeSO₄ and NaH₂PO₂ on the deposit composition content; （3） the effects of FeSO₄ concentrations, NaH₂PO₂ concentrations and the various complex ratios on the resistance rate of deposit. We measured the deposit composition contents through the X-ray photoelectron spectroscopy （XPS） and the deposit resistance with the digital multimeter. The electroless bath is very stable as proved by the Pd-salt test. The resistance rate of the Ni-Fe-P alloy glass fiber reaches 7.32×10^-4 Ω·cm. We used the thermal shock experiment to analyze qualitatively the adhesion between the coatings and glass fiber.更多还原
