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

Abstract

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 cellulosesilver-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.

Silver Nanoparticles Incorporated PVA‐MC Blends: A Systematic Approach To Understand Its Properties For Food Packaging Applications

“…Moreover, it is observed that the formed nanoparticles are homogeneously dispersed and distributed throughout the film surface, which is further stabilized by the polymer (Figure 6c). [26] Even though, there has been significant nanoparticle aggregation, no direct fusion has been observed due to the presence of capping agents. Conversely, Figure 6d represents the dispersion of AgNPs formed by the addition of AgNO 3 into PVA/MC cross‐linked blend, which were slightly larger size than AgNPs present in the uncross‐linked blend.…”

“…(14) 2.6.3 Synthesis the colloidal solution using Xanthan gum A beaker containing 150 ml of DI water at laboratory temperature, sprinkle 0.8042 g of Xanthan gum (dynamic viscosity of a 2% solution 4000 cl) on it and stir vigorously to ensure that the material is dispersed in the solvent, and a clear colloidal solution is formed, and 0.02 g of the nanomaterial is dispersed In a beaker containing 50 ml of deionized water for 60 minutes, then add the colloidal substance of DI water and stir the solution for 30 minutes at room temperature, and finally the formation of a silver colloidal solution of methyl-dopa pharmaceutical nanocomposites can be observed. (15) 2.6.4 Synthesis a medical mask containing the nanocolloidal solution From the concentrated solution of methyldopa nanocompounds, three different concentrations (100, 50, and 150) ppm were prepared. In the previously prepared solutions, small previously prepared pieces of masks measuring (55) cm in size began to be soaked for a period of (5-7) hours.…”

A Review on Different Plants Extract Mediated Silver Nanoparticles: Preparation, Antimicrobials, and Antioxidant

“…By the same group, many nanoparticles were fabricated in the presence of chitin, ascorbic acid, sodium alginate, and pectin [37][38][39]. Silver nanoparticles or silver blended zinc oxide have been incorporated into the fabric, especially cotton, with different methods in order to reduce the proliferation of bacteria and germs [40][41][42][43]. Several studies have reported that the number and position of surface plasmon resonance analysis peaks differ according to the shape and size of silver nanoparticles, as these particles tend to show different physical and biological properties that depend on their size and shape [44][45][46].…”
