| 摘 要： | 在哈克流变仪中将炭黑(CB)与聚苯乙烯(PS)、尼龙6(PA6)共混,研究了CB在PS/PA6/CB共混体系中的分散情况及CB含量和PS与PA6的质量比对PS/PA6/CB共混体系导电性能、微观形态的影响。结果表明,CB在PS/PA6/CB共混体系中只分散在PA6中;PS/PA6/CB共混体系的导电性能随着CB含量的增加而增强,CB的体积分数在20%~40%时,PS/PA6/CB共混体系的电导率增幅明显;PS、PA6两相的微观尺寸随CB含量增加而变小;PS/PA6/CB共混体系中PS与PA6质量比约为80/20时,PS/PA6/CB共混体系的导电性能最好。

| Abstract: | Polystyrene(PS),nylon 6(PA6) and carbon black(CB) are blended in Haake blender.The dispersion of CB in PS/PA6/CB blend and the effects of content of CB and mass ratio of PS to PA6 on the conductivity and morphology of PS/PA6/CB blend are studied.The results show that CB is dispersed in PA6 phase in PS/PA6/CB blend;the conductivity of PS/PA6/CB blend gets better with CB content increasing,especially when the volume fraction of CB is 20%-40%;the microcosmic sizes of PS and PA6 phases turn small when CB content increases;the conductivity of PS/PA6/CB blend is the best when the mass ratio of PS to PA6 is(about) 80/20. |
