摘　　要：介绍了化学镀的基本原理和主要特点,重点阐述了以金属、无机非金属、聚合物等粉料为基体,采用化学镀技术制备具有不同粒度、密度、长径比、导电性、电磁屏蔽效能和抗氧化性的电磁屏蔽用金属包覆型导电复合填料的国内外研究现状和进展,分析比较了这3类电磁屏蔽用导电复合填料的优缺点,指出其目前还存在电磁阻抗不匹配、电磁综合性能不高和表面性质差异过大的主要问题,建议今后还需进一步研究复合填料组成、化学镀配方和工艺等,以研制出性价比更高的电磁屏蔽用复合填料。The basic theory and main features about electroless plating are introduced. The situation of the research and development of metal coated conductive composite fillers with various sizes, densities, length-diameter ratios, conductivities, shielding properties and inoxidizabilities for electromagnetic shielding at home and abroad are emphatically reviewed, which are prepared using metal, inorganic nonmetallic and polymer powders as substrates by electroless plating. The advantages and disadvantages of these three types of metal coated conductive composite fillers are analyzed and compared. The main problems that exist at present such as electromagnetic impedance mismatch, low electromagnetic comprehensive performances and big surface property differences are pointed out. And the further study such as the compositions of the fillers, the technology and the formula of electroless plating are suggested in order to develop electromagnetic shielding composite fillers with higher performance-price ratios. This has very important significance and function to prevent and control electromagnetic radiation pollution.
