“…Inorganic polymer nanocomposites have become of major interest over the past few decades owing to their numerous applications and their low cost. In general, the insertion of inorganic fillers, including metallic oxides, metal powders, ceramics, nonmetal oxides and natural fillers, into polymeric matrices results in the enhancement of the thermal, mechanical, electrical, and rheological properties of the generated composites . The choice of inorganic filler depends on the desired and/or required properties.…”

This research discusses the mechanical behavior and the microstructure of high‐density polyethylene (HDPE)‐based composites, manufactured using the melt‐mixing and thermal‐pressing techniques, where HDPE is mixed with various percentages of either bulk lead monoxide (bulk PbO) or PbO nanoparticles (PbO‐NPs) acting as fillers. The scanning electron microscope and the field emission transmission electron microscope were utilized to identify the morphology of polymeric composites. Both showed the proper dispersion of PbO in the HDPE matrix without substantial agglomerations. The effect of PbO on the thermal behavior of the HDPE was studied using the thermogravimetric analysis. Tensile tests were implemented to find out how the mechanical characteristics of the composites were affected. Yield stress, % elongation at break, stiffness, tensile energy (toughness), ultimate tensile strength, and ultimate tensile strain were elucidated in this work. The values of stiffness, ultimate tensile strength, and yield stress increased by increasing either the bulk PbO or PbO‐NPs' loading up to 40.0 wt % with reference to the hosting matrix. The values of ultimate tensile strain, tensile energy, and % elongation at break of the assembled composites diminished dramatically by increasing the filler's content from 10.0 to 50.0 wt %. Besides, composites with PbO‐NPs as a filler were identified as having higher mechanical characteristics than those with bulk PbO for the same wt %. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

“…The smooth transfer of electrons responsible for conductivity throughout the matrix takes place only if the filler particles are geometrically connected to each other, establishing an intricate network. The improved electrical behaviour of Cu–Al 2 O 3 /PVC might be associated with the formation of a conducting pathway that facilitated smooth electron transfer throughout the matrix …”

The commencement of the industrial revolution paved the way for the fabrication of flexible polymers with high-strength metalloceramics as novel materials of all kinds. Fabricating metal-ceramic/polymer conductive composites is one such dimension followed for the present research work making use of the properties of the three components. Electroless deposition, for permanent metallic coating, was performed to coat Al 2 O 3 with metallic Cu followed by the inclusion of the Cu-Al 2 O 3 filler into a poly(vinyl chloride) (PVC) matrix. X-ray diffraction and energy-dispersive X-ray studies predicted a prominent growth of metallic Cu crystallites onto Al 2 O 3 with an increased average size and variation in elemental composition, respectively, when compared to pristine Al 2 O 3 . Morphological behaviour via scanning electron microscopy also envisioned uniform Cu coating onto Al 2 O 3 and a homogeneous dispersion throughout the polymer matrix. When incorporated into PVC, electrical conductivity analysis highlighted a distinct variation in composite phases from insulating (7.14 × 10 −16 S cm −1 ) to semiconducting behaviour (8.33 × 10 −5 S cm −1 ) as a function of Cu-Al 2 O 3 filler. Mechanical behaviour (tensile strength, Young's modulus and elongation at break) and thermal properties of the prepared composites also indicated a substantial improvement in material strength with Cu-Al 2 O 3 incorporation. The enhanced electrical conductivity along with improved thermomechanical status with significant filler-matrix interaction permits the potential usage of such novel composites in a range of state-of-the-art semiconducting electronic devices.

“…The electron transfer responsible for conductivity throughout the Cu–Al 2 O 3 /PS- b -(PE- r -B)- b -PS- g -MA matrix takes place when interaction zones between filler and matrix find connections ( Figure 7 ), establishing a web [ 38 , 39 , 40 , 41 ]. Cu–Al 2 O 3 /PS- b -(PE- r -B)- b -PS- g -MA composites are cost-effective materials, as they showed enhanced electrical conductivity and they are easy to prepare compared to previously cited literature [ 42 ].…”

Technological advancements and development of new materials may lead to the manufacture of sustainable energy-conducting devices used in the energy sector. This research attempts to fabricate novel electroconductive and mechanically stable nanocomposites via an electroless deposition (ELD) technique using electrically insulating materials. Metallic Cu is coated onto Al2O3 by ELD, and the prepared filler is then integrated (2–14 wt %) into a matrix of polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene-graft-maleic anhydride (PS-b-(PE-r-B)-b-PS-g-MA). Considerable variations in composite phases with filler inclusion exist. The Cu crystallite growth onto Al2O3 was evaluated by X-ray diffraction (XRD) analysis and energy dispersive spectrometry (EDS). Scanning electron microscopy (SEM) depicts a uniform Cu coating on Al2O3, while homogeneous filler dispersion is exhibited in the case of composites. The electrical behavior of composites is enhanced drastically (7.7 × 10−5 S/cm) upon incorporation of Cu–Al2O3 into an insulating polymer matrix (4.4 × 10−16 S/cm). Moreover, mechanical (Young’s modulus, tensile strength and % elongation at break) and thermal (thermogravimetric analysis (TGA), derivative thermogravimetry (DTG), and differential scanning calorimetry (DSC)) properties of the nanocomposites also improve substantially. These composites are likely to meet the demands of modern high-strength electroconductive devices.
