Fabrication of silver nanoparticles/polyaniline composite thin films using Layer-by-Layer self-assembly technique for ammonia sensing

- Polyaniline blend CoPSS was synthesized using interfacial polymerization method.
- Polyaniline blend CoPSS was used as the stabilizing agent for silver nanoparticles.
- Multilayer films of Ag nanoparticles/polyaniline-CoPSS were constructed by LbL method.
- The obtained Ag nanoparticles would be of significance for ammonia sensing.
- The color of multilayer thin films was changed from orange-red to yellow.
