|
摘要
为改善聚苯胺(PANI)纳米复合材料的导电性能,采用原位氧化还原法合成PDAAB@rGO@AgNPs新型光响应导电复合材料。结果表明:PDAAB@rGO@AgNPs导电效果良好,当rGO的掺杂质量为1.25 mg,电导率达到最大值,为33 S/m,紫外光照射1 h,电导率高达100 S/m;在紫外光/可见光回复下,该复合材料的电导率可以实现光控循环。
In order to improve the electrical conductivity of polyaniline(PANI) nanocomposites,PDAAB@rGO@AgNPs conductive nanocomposites were synthesized by in.situ redox method. The results show that PDAAB@rGO@AgNPs had good electrical conductivity. When the doping amount of rGO is 1.25 mg,the electrical conductivity reaches a maximum of 33 S/m. If the nanocomposites are exposed to ultraviolet light for 1 h,it can reach up to 100 S/m. Under the recovery of ultraviolet/visible,the electrical conductivity of the composite can achieve a light.controlled cycle.
