| 摘 要： | 超临界二氧化碳流体对苎麻纤维有明显的膨化作用.采用超临界二氧化碳流体( SCCO2)技术对苎麻织物进行预处理,能够有效去除苎麻纤维中的杂质及木质素;利用超临界二氧化碳流体的高溶解能力,将六氟乙酰丙酮钯(Ⅱ)溶解并注入苎麻纤维中,并通过化学镀铜制备柔性抗电磁波屏蔽材料.结果表明,采用乙醇作为共溶剂,可以提高钯络合物的注入效果,再经化学镀铜,苎麻织物表现出良好的电磁屏蔽效果,在10～1 000 MHz的频率范围内,电磁屏蔽效果可达到63～92 dB.

| Abstract: | Supercritical CO2(SCCO2) fluid technique is applied to the pretreatment of ramie fabrics.It can remove the impurities and lignin with good swelling action.Flexible electromagnetic shielding material is prepared by electroless copper plating with the organometallic complex Palladium(II)-hexafluoroacetylacetonate,which is dissolved in SCCO2 and impregnated into the ramie fibers.Results show that the impregnation effect can be improved with alcohol as a co-solvent,and the ramie fabric features high electromagn... |
