利用界面能原理使CB选择性分布于HDPE中成为复合导电相,固定CB在HDPE中的质量分数(20wt%),控制CB/HDPE导电相在iPP中的含量,制备出一系列三元(iPP/HDPE/CB)导电复合材料,并研究其导电逾渗和流变逾渗行为.结果表明,在复合导电相含量为20 wt%时复合材料内即形成导电网络,在复合导电相含量30 wt%时出现流变网络.只有当复合导电相在材料中形成连续相时(60 wt%),损耗因子在频率扫描中才出现峰值。 Based on the interface energy theory, CB was selectively distributed in HDPE to form a composite conductive phase. The mass fraction of CB in HDPE was fixed (20wt%), and the content of CB / HDPE conductive phase in iPP was controlled to prepare a series of ternary / HDPE / CB) composites were prepared and the conductive percolation and rheological percolation were studied.The results showed that the conductive network was formed when the composite conductive phase content was 20 wt% The rheological network appears at% The loss factor peaks only in the frequency sweep only when the composite conductive phase forms a continuous phase in the material (60 wt%).
