“…Among all the methods, special attention is being devoted to the synthesis of PANI through electrochemical polymerisation, interfacial polymerisation, in situ chemical oxidative polymerisation and rapid mixed polymerisation methods. Tremendous efforts have been made to prepare PANI composites with various filler materials such as carbon nanotubes, [8,9] zeolites, [10] SiO 2 [11], graphene [12], graphite [13], nanodiamonds [14], mesoporous carbon, montmorillonite clay, zeolite [15], TiO 2 [16], titanate, ZnO [17], quantum dots [18], noble metal nanoparticles [19], organic polymer cores, [20,21] etc. with an aim to combine the merits of each individual component.…”
