“…CB particles could also be used as nanofillers to enhance polymer nanocomposites' properties. Incorporation of CB nanofillers into virgin PP matrix improves thermal stability (78,79), flammability (80), mechanical strength (81), electric conductivity (82) and rheological behavior (83) of resulting CB/PP nanocomposite.…”

Recycling process seems to be the most efficient way to reduce ecological impacts of used polymers. Nevertheless, the properties of the recycled PP polymer are proved to be insufficient during its reuse, particularly with regard to its thermo-mechanical and rheological behaviors. The incorporation of nanoparticles as fillers into polymer matrix seems to be one of the most successful solutions to upgrade recycled PP polymer. This paper presents an overview on the application of different nanofillers such as clay, calcium carbonate (CaCO 3), Silica (SiO 2), Zinc Oxide (ZnO), carbon black (CB), carbon nanotubes (CNT), antioxidizers and others into recycled PP matrix. Literature works on the effects of nanofillers on obtained nanocomposites are extensively studied. The first section deals with PP recycling and its impact on thermal, mechanical and rheological properties of the polymer. Then, the second part summarizes recent studies on the effects of nanoparticles incorporation on thermo-mechanical and rheological properties of recycled PP. Finally, recyclability of PP-based nanocomposites is discussed.

Hexaphenoxycyclotriphosphazene (HPCTP) and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) were used to flame retard N,N,N′,N′-tetraglycidyl-4,4′-diaminodiphenylmethane epoxy resins. The curing behaviors and glass transition temperature were investigated by differential scanning calorimetry. The limiting oxygen index (LOI), UL-94 vertical burning, and cone calorimetry tests were used to assess the flame retardancy of the cured epoxy resins. The increase in LOI value and UL-94 rating was strongly dependent on the phosphorus content. The reduction in peak of heat release rate and total heat release showed that the incorporation of flame retardants could improve the flame retardancy of epoxy resin. The higher smoke release and CO yield of the flame-retardant epoxy resins indicated that both DOPO and HPCTP showed a gas phase flame retardancy action. Thermogravimetric analysis of the flame-retardant epoxy resins indicated that the incorporation of the flame retardants reduced the initial decomposition temperature of epoxy resin.

“…1a, with the increase in CB content, the thermal decomposition curves shifted significantly to a higher temperature range, indicating an improvement on thermal stability. According to the data listed in Table 2, both T 5mass% and T 10mass% (corresponding to 5 and 10 mass% mass loss, respectively) of PP gradually increased with the addition of CB content, which was attributed to the trap peroxyl radicals effect of CB on inhibiting the decomposition of PP matrix on onset stage [25,27,28].…”

Nanosized carbon black (CB) was introduced into polypropylene/maleic anhydride-grafted polyolefin elastomer/intumescent flame retardant (PP/POE-MA/IFR) system to investigate the effect of nanofiller as synergist on thermal, electrical and mechanical properties of polymer composites. With 5 mass% CB into PP/POE-MA/IFR system (POFC5), the T max (corresponded to the temperature at the maximum mass loss rate) under air was increased by 122.4°C; its limited oxygen index was as high as 31.4%; its vertical burning rating (UL-94) reached V0, and the peak value of heat release rate was decreased to only 19% of neat PP in cone calorimeter testing. Moreover, PP composites exhibited good electrical conductivity with more than 1.6 mass% CB, which is a low loading level to reach the critical percolation concentration. In addition, a good balance on stiffness and toughness of PP composites was achieved; especially, Young's moduli and impact strength of POFC5 were increased to 1.26 and 2.5 times in comparison with that of neat PP, respectively. These results indicated that CB was an effective synergist in multi-component PP composites to simultaneously improve thermal, electrical and mechanical properties.
