【摘要】：目的采用铁网催化的方法在碳纤维表面化学镀镍,取代传统的钯活化法。方法经去胶、粗化、分散前处理工艺后,采用铁网包覆对碳纤维化学镀镍进行催化反应,通过称重法、扫描电镜(SEM)研究催化时间、碳纤维分散状况以及粗化时间对镀层的影响,并通过能谱(EDS)对铁网催化法和钯活化法制备的镀层进行成分分析。结果铁网催化在10 min内时镀层存在缺陷,催化20 min镀层以颗粒状泡沫镍存在,超声分散优于分散剂CMC的分散效果。获得铁网催化法最佳工艺为:丙酮浸泡4 h去胶,80℃粗化处理15 min,超声分散,铁网包覆催化20 min诱导起镀,化学镀20 min。制备的镀层均匀、致密,从镀层各组分含量分析,并不差于钯活化法制备的镍镀层。结论铁网催化法可以在碳纤维上获得质量良好的镍-磷镀层。
[Abstract]:Aim to replace the traditional palladium activation method by electroless nickel plating on carbon fiber surface by iron mesh catalysis. Methods after degumming, coarsening and dispersion pretreatment, the catalytic reaction of carbon fiber electroless nickel plating was carried out by using iron mesh coating. The catalytic time was studied by means of weighing method and scanning electron microscope (SEM). The dispersion of carbon fiber and the effect of coarsening time on the coating were studied. The composition of the coating prepared by catalytic method of iron mesh and palladium activation method was analyzed by energy dispersive (EDS). Results there were defects in the coating of iron mesh catalyst within 10 min, and the catalytic 20 min coating was in the form of granular nickel foam. The ultrasonic dispersion was better than that of dispersant CMC. The optimum conditions of iron mesh catalytic method are as follows: acetone immersion for 4 h, roughening treatment at 80 鈩，
