Examples
- Hot stretching ratio ( hsr ) was maintained at 3 . 96 , cb content was changed . the results indicate that when the cb content increases , the room temperature resistivity of composites decreases . at the cb content of 12phr , the room temperature resistivity of blends sharply reduces , and composites change from insulator to conductor , the value is entitled the percolation threshold ; at the cb content of 20phr , the room temperature resistivity of composites achieves 10 ~ ( 2 ) cm
结果表明:随炭黑含量增加，复合材料的体积电阻率降低，当炭黑含量达到12phr ( phr指每一百份树脂中所含填充物的重量份数)左右时，复合材料的体积电阻率急剧下降，此时一复合材料由绝缘体向导体转变，这个值被称为逾渗阀值;当炭黑含量到20phr时，复合材料的体积电阻率达到1 。
