“…who used the divinylbenzene as a crosslinking polymer at a low concentration to form the low dense polymerized composite; meanwhile, in the absence of crosslinking agent, the agglomeration of PANI was much easier to form. As reported by Ghani et al ., the poly(vinyl chloride)/poly(ethylene oxide)/PANI blend became inhomogeneous upon the inclusion of PANI for more than 5 wt % which subsequently contributed to the decrease in tensile strength and modulus of elasticity. This is similar to both negative trends in tensile (Figure ) and bending properties (Figure ) reported in our study.…”

This research was conducted to fabricate thermoplastic natural rubber/polyaniline (TPNR/PANI) blends via melt blending method using an internal mixer and followed by compression molding. The effects of PANI contents between 1 and 5 wt % PANI in the TPNR blends on the mechanical properties, thermal stability, electrical conductivity (impedance), and morphology observation were investigated. The TPNR/3 wt % PANI sample exhibited the highest tensile strength (3.7 MPa), elongation at break (583%), flexural strength (1.8 MPa), flexural modulus (37.0 MPa), and impact strength (7.1 kJ m −2 ). From the aspect of thermal properties, it was found that with the addition of PANI, the thermal stability of the TPNR/PANI increased. Comparing to nonconductive TPNR sample, the incorporation of PANI promoted the electrical conductivity characteristic to PANI-filled TPNR blends which showing a magnitude order of 10 −9 S cm −1 . Scanning electron microscopy micrograph revealed the good distribution of PANI at the optimum content (3 wt % PANI) in the TPNR blends and the good interaction between TPNR and PANI. It can be concluded that the TPNR blends incorporated with a low loading of PANI could be a newly good conductive material.

“…A slight increase in the thermal stability of PANI-PVC over PVC might be due to the formation of barrier of PANI particles that decrease the permeability of volatile degradation products from the PVC films. 2,7 The enhanced stability of Ag.PANI-PVC (46% decomposition) composite film can also be attributed to the presence of thermally insulating Ag.PANI interface in the composite. Weight loss at 430 C is due to the decomposition of ethylene unit from PVC backbone.…”

“…[1][2][3] Blending of PVC with polyaniline (PANI) combines the excellent mechanical properties of PVC with electrical and chemical properties of PANI. [4][5][6][7] Apart from this, PANI possess high conductivity, good environmental stability, and catalytic and photocatalytic activity when doped with noble metals. [8][9][10] However, its low mechanical stability and insolubility in most of the solvents are the major problems to use PANI alone in desirable applications.…”

Silver-doped polyaniline–polyvinyl chloride (PVC) nanocomposite films (Ag.PANI–PVC) were synthesized by non-solvent-induced phase inversion method. The nanomaterials were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, ultraviolet, and field emission scanning electron microscopy analysis. Thermal stability and tensile strength of the Ag-doped and undoped PANI–PVC films were studied. The photocatalytic activity of the nanocomposites on methylene blue dye under visible light was evaluated at different initial concentrations of the dye. Silver-doped nanocomposites exhibited excellent photodegradation efficiency. The kinetics of photocatalysis fit well to the pseudo first-order model. Antibacterial performance of the samples was tested against Staphylococcus aureus and Escherichia coli bacteria by agar disc diffusion method. It was observed that Ag.PANI–PVC and Ag.PANI have antagonistic effects against the growth of gram-positive bacteria ( S. aureus) and gram-negative bacteria ( E. coli) with inhibition zones in the range of 10–35 mm.

The main aim of this study is to investigate the effect of silver-doped zinc oxide (Ag-ZnO) loading on the structural, morphological, thermal and electrical properties, and gas sensing behavior of polypyrrole (PPy)/phenothiazine (PTZ)-blend nanocomposites. The composites are characterized by FTIR, XRD, SEM, TEM, DSC, TGA, and impedance studies. FTIR spectra exhibit the presence of Ag-ZnO in the PPy/PTZ blend. XRD analysis shows that the semicrystalline behavior of the polymer blend is greatly enhanced by the addition of Ag-doped ZnO particles. Uniform dispersion of nanoparticles in the polymer is obtained from SEM analysis. The TEM images confirm the presence of spherically shaped nanoparticles in PPy/PTZ blend with a size of 10-25 nm. The DSC measurement indicates that the glass transition temperature of PPy/PTZ blend was significantly improved in the presence of Ag-doped ZnO nanoparticles. The thermal decomposition temperature of nanocomposite obtained from TGA shows an increase with increase in the content of Ag-ZnO particles. The incorporation of Ag-doped ZnO nanoparticles to PPy/PTZ blend exhibit increase in the AC conductivity and dielectric properties of the nanocomposite, due to the pilling of charges at the extended interface of the composite system. The DC conductivity of the nanocomposite increases with the loading of nanoparticles. The ammonia gas sensing performance of PPy/PTZ/Ag-ZnO nanocomposite is analyzed, and the result shows that the fabricated blend composite can be used as a promising candidate for the easy access of gas molecules.
