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 flame retardancy of the composites was evidently improved, as shown in the nanocomposites with the synthesized Fe-OMT (organically modified Fe-MMT, where Al 3+ inside the crystal lattice of montmorillonite is replaced by Fe 3+ have been adopted. [50,51] Generally, the improvements of the flame retardant properties are due to both the strong interactions between the silicate layers and the polymeric chains, and the presence of Fe 3+ could catalyze the formation of char layers, which has been confirmed by our previous work. During thermal degradation, Fe 3+ could promote the vulcanization of polymers and increase the char formation.…”

The review on the fire safety of polymer/layered compounds nanocomposites are summarized and discussed. Emphasis on flammable performance of polymer nanocomposites containing layered compounds, mainly montmorillonite, layered double hydroxides, layered metal phosphate, layered carbon materials and the compounds combined with conventional flame retardant additives, are also introduced based on the open literatures. Derived from those research, the combination of multiple methods and technologies including the catalyzing effect metal ion and the barrier effect of the layered compounds, are predicted to have a high probability to enhance char formation, restrain the release of combustible gases and improve the flame retardancy of polymeric materials.

A novel pentaerythritol stearate ester‐based zinc alkoxide (PSE‐Zn) was synthesized through a two‐step method. Zinc ethoxide was first prepared from zinc acetate and ethanol, and then with ethanol as the solvent, the obtained zinc ethoxide ester was heated together with pentaerythritol stearate to produce PSE‐Zn. PSE‐Zn could be used as a promising poly(vinyl chloride) (PVC) thermal stabilizer. Conductivity tests, thermal aging tests, and UV‐visible spectroscopy were used to study the thermal stabilization performance of the thermal stabilizers of PSE‐Zn on PVC. The results showed that, with a lower melting point and a good compatibility with PVC, PSE‐Zn presented a significant improvement in maintaining the initial color of PVC. However, the color of PVC stabilized with pure PSE‐Zn began to degrade when the sample was heated at 180°C for 60 min indicating the unsatisfactory long‐term thermal stability presented by PSE‐Zn on PVC. So, some commercial thermal stabilizers, for example, calcium stearate (CaSt2), zinc stearate (ZnSt2), or CaSt2/ZnSt2 were employed along with PSE‐Zn to further improve the stabilizing performance. The results showed that there was a synergistic effect that was between 2 phr PSE‐Zn and 2 phr CaSt2 and made the stabilized PVC possess the best thermal stability. Because of the presence of free hydroxyl in PSE‐Zn, which could chelate ZnCl2, PSE‐Zn can then restrain “zinc‐burning” phenomenon when PSE‐Zn and ZnSt2 were used together. It was also found that PVC stabilized with 3 phr PSE‐Zn and 1 phr CaSt2/ZnSt2 had the best color stability. The mechanism of thermal stability of PSE‐Zn was also discussed. As a metal alkoxide, PSE‐Zn is readily to neutralize HCl. In addition, PSE‐Zn is able to replace the allyl chloride to terminate the dehydrochlorination of PVC. Moreover, because of the stearate radicals, PSE‐Zn had a very low melting point, a better compatibility with PVC, and a lubrication action. With these excellent properties, PSE‐Zn would be able to make PVC achieve an excellent initial color and a long‐term stability. J. VINYL ADDIT.
