A novel method for the preparation of conductive methyl cellulose-silver nanoparticles-polyaniline-nanocomposite

A novel green method for the synthesis of conductive nanocomposite -using silver nitrate, methyl cellulose (MC), glycerol, and aniline- was adopted. Here, silver nitrate was used as a precursor, methyl cellulose as both reducing and capping agent, glycerol as a co-reducing and ductility agent and water as solvent. While silver nitrate oxidizes aniline to polyaniline, it is reduced to silver nanoparticles. Doing so, both conductive polyaniline and conductive silver nanoparticle were in-situ synthesized via the formation of methyl cellulose- silver-polyaniline nanocomposite. Reproducibility of the nanocomposite revealed that the synthesis process is consistent. The nanocomposite film was characterized by FTIR, SEM, EDAX, XRD, and conductivity. XRD pattern showed poly crystallinity. TEM of the colloidal solution showed different particle shapes of AgNPs with size from 4-36 nm and d-spacing of 0.22 nm. SAED exhibits ring pattern with bright spots displaying polycrystallinity. Nanocomposite film, coated glass, cotton and polyester fabrics showed promising conductivity.
