高剪切分散对多壁碳纳米管/VARTM用环氧树脂导电性能的影响
Influence of High Shear Dispersion on Conductive Properties of Multi Wall Carbon Nanotubes/VARTM Epoxy Resin Composites
摘要
Abstract
The dispersion of multi-wall carbon nanotubes (MWNTs) in epoxy resin was facilitated with the assistance of high shear dispersing emulsifier .The MWNTs/EP composites was manufactured using vacuum assisted resin transfer molding (VARTM ) technology ,and the conductive properties affected by the speed and time were studied .The results showed that the conductive properties of the composite in-creased at first and then decreased with the increasing high shear dispersing time or speed .A threshold was captured when the high shear dispersing was 30 min and speed was 22000 r/min .The addition of 1 .5％MWNTs (w t .％ ) can decrease the surface resistance of epoxy resin within 5 orders of magnitude .The effect of dispersion of MWNTs in EP was also verified by scanning electron microscopy (SEM ) .关键词
