摘要
将多壁碳纳米管(MWCNT)加入硬质聚氨酯泡沫塑料(PUF)中,研究了MWCNT/PUF复合材料的密度、电导率、压缩强度和电磁屏蔽效能(EMI SE)。结果表明,MWCNT/PUF复合材料的密度和压缩强度随MWCNT含量的增加先增大后减小;电导率和电磁屏蔽效能随MWCNT含量的增加而增大,低MWCNT含量时增长速率快。
The multi walled carbon nanotubes （MWCNT） were added to the polyurethane foam （PUF）. The density, electrical conductivity, compressive strength and electromagnetic shielding effectiveness （EMI SE ） of MWCNT/PUF composite were studied. The results showed that the density and compressive strength of MWCNT/ PUF composites were increased at first and then decreased with the increase of MWCNT content. The electrical con- ductivity and EMI SE of MWCNT/PUF composites were increased with the increase of MWCNT content, and the growth rate was fast at low MWCNT content.
