先通过原位聚合制备聚苯胺(PANI),然后经过碳化处理制备了多孔的碳化聚苯胺(C-PANI)纳米片。分别利用TEM、FT-IR、XRD、全自动比表面及孔隙度分析仪及恒流充放电等对其形貌、表面结构、晶体结构、比表面积及电容性能进行表征,并对该纳米片的形成机理进行了探讨。同时,电容性能测试结果表明该纳米片显示较理想的电容值,这可能归因于碳化聚苯胺纳米片拥有较大的比表面积,有利于电解液离子的传输和渗透;碳化聚苯胺中氮元素的存在使其又具有赝电容效应,也有助于电容性能的提高。
Polyaniline (PANI) was prepared by in-situ polymerization and then porous carbonized polyaniline (C-PANI) nanosheets were prepared by carbonization. The morphology, surface structure, crystal structure, specific surface area and capacitance of the nanosheets were characterized by TEM, FT-IR, XRD, automatic surface area and porosity analyzer and constant current charge and discharge, Formation mechanism is discussed. At the same time, the capacitance performance test results show that the nanosheets show an ideal capacitance value, which may be attributed to the larger specific surface area of the polyaniline polyaniline sheet, which is conducive to the transport and penetration of electrolyte ions; The existence of it has pseudocapacitive effect, but also contribute to the improvement of capacitance.
