“…The solely conducting polymer faces the difficulty of processing due to its thermosetting nature such as poor thermal stability and solubility . Therefore, blending of PANI with other conventional polymers has been commonly applied for the obtention of processable conducting material . The study of Kazimi showed an increase in thermal stability and electrical conductivity properties when the PANI was incorporated in functionalized LDPE blend.…”

“…Nevertheless, most of the research related to PANI/polyolefin blend was conducted using solution blending method because of the need of solvent as a third component to improve the miscibility between polar PANI and nonpolar polyolefin. In which miscibility is a critical factor to affect the resultant blend or composite features . Annala and Lofgren .…”

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.

“…1 Techniques employed to synthesize such composites include in situ chemical polymerization, 3-10 electrochemical polymerization, 11,12 grafting, [13][14][15][16] and polymer blending. [17][18][19][20] Among the commonly used ICPs and their derivatives, polyaniline (PANI) is one of the most studied due to its good environmental stability, higher electrical conductivity, and lower materials and synthesis costs. 1 Among the various techniques employed for PANI composite membranes synthesis, chemical oxidative polymerization of aniline has gained special interest due to its simplicity and low cost.…”

Polyaniline (PANI) can be deposited either on the surface or in the bulk of a microporous membrane by various chemical oxidative polymerization techniques. Each technique has distinctive effects on the PANI site and extent of deposition on the base membrane. In the present study, mixed cellulose ester (ME) membranes with tortuous pore morphology were used as base membranes. The chemical oxidative polymerization techniques employed, included polymerization using an in-house-built two-compartment permeation cell. The resultant composite membranes have been characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR-ATR), and electrical conductivity measurements. The results showed that PANI was layered on the pore walls of the membrane using two-compartment permeation cell. Vapor-phase polymerization yielded a surface layer of PANI with little deposition in the bulk. A distorted PANI surface layer was achieved by solution-phase (dip) polymerization. Moreover, asymmetric PANI deposition within the membrane bulk was evidenced using two-compartment permeation cell. Composite membranes synthesized using two-compartment cell showed highest levels of conductivity (approximately 10(-2) S/cm) as compared to the membranes modified by single-step solution-phase polymerization. FTIR-ATR results indicated the extent of PANI coating and its oxidation state which was identified as doped emeraldine PANI, from all the employed techniques. Asymmetric deposition and extent have been explained in terms of the physical and chemical reaction steps involved in the heterogeneous aniline polymerization reactions in the two-compartment cell technique.

“…The earliest and most widely used conducting polymeric systems were composites in which an insulating polymer matrix was filled with particulate or fibrous conductive filler, such as a carbon or metal, to impart high conductivity, however conducting polymers such as polyaniline and polypyrrole now offer excellent electrical and mechanical properties [1]. In recent year preparation of composites polyolefin with intrinsically conducting polymers (ICP) especially polyaniline has received great attention because of their unique properties and applications in various electrical devices [2]- [4].…”

Nano composite based on polyaniline (PANI) nano fibers filler and chromic acid functionalized low density polyethylene (LDPE) matrix with biocompatibility and low percolation threshold value was prepared via twin screw extrusion process. Density measurement, Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Electron Microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDX), X-ray crystallography (XRD), Brunauer, Emmett and Teller analysis (BET), Thermo Gravimetric (TGA), Differential Scanning Calorimetery (DSC) and Four-Probe Conductivity measurements are reported. As low density polyethylene functionalization renders LDPE more biocompatible, it also facilitates conductivity due to carbon carbon double bonds, sulfonic, and carbonyl group moieties. PANI nano fibers also assist in charge transfer mechanism of resultant composite. Overall results indicate the formation of highly stable nanocomposite materials, with good physiochemical properties and conductivity. The resultant blend may prove beneficial as a low cost biocompatible and electrically simulated nerve tissue repair scaffolds.
