Effects of (conductive polypyrrole)‐modified tire dust on the mechanical, electrical, and morphology properties of (low‐density polyethylene)/(tire dust) composites

Abstract

The effects of conductive polypyrrole (PPy) as a coupling agent on the mechanical properties, morphology, electrical properties, and thermal degradation of (low‐density polyethylene)/(tire dust) (LDPE/TD) composites were studied. LDPE/TD composites with different TD loadings and added PPy were prepared with a Brabender Plasticorder. The LDPE/TDT (treated with PPy) composites showed higher values of tensile strength, modulus of elasticity, electrical conductivity, thermal stability, and swelling resistance than LDPE/TD composites. Scanning electron microscopy morphology revealed that the interfacial adhesion between the TD and LDPE phases was improved by the addition of conductive PPy. J. VINYL ADDIT.

Effect of type of conductive fillers and poly (ethylene glycol) diglycidyl ether on the electrical conductivity and morphology properties of poly (vinyl chloride)/poly (ethylene oxide) conductive films

“…The electrical measurements were obtained using Keithley Model 4200 Semiconductor Characterization System made in England. The samples were measured with voltage varying from 0 to 10 V. The conductivity was calculated using its relationship with resistivity [9]. The resistivity can be calculated using the Eq.…”

“…Among them, all‐organic dielectric polymer composites obtained by using organic polymers as fillers is a very effective and promising strategy. [ 19–21 ] There are two advantages by using organic polymer as fillers: (1) their electrical conductivity can be adjusted over a wide range; (2) the interaction between fillers and matrix is better than inorganic filler/organic polymer‐based composites, which leads to better mechanical properties. [ 5 ] For example, using organic polymers such as copper phthalocyanine, polypyrrole, polyaniline, etc., as fillers to fill the polymer matrix can well maintain the flexibility of the matrix.…”
