电阻率的峰值随着Fe的增加而增大，并且峰值对应的温度TIM向低温移动，随着外加磁场的增大电阻下降，产生MR效应，这是因为随着掺杂的增加，自旋无序增加，外场的增加抑制了自旋的扰动，在顺磁温区内，电子自旋形成了随机的磁结构，产生电子局域，破坏了极化子形成的环境，因此输运机制由绝热极化子输运转变为变程跳跃机制。

Sensing ability of PSS/PANI self-assembled film with different doping/dedoping structure to DMMP and CEES was investigated. Results demonstrate that the gas sensitivity of PSS/PANI self-assembled film is affected by the size of dopant counterions.
