“…Bottcher’s model predicts fairly well the k values until 20 wt% of LGNa particles. Bottcher’s model as also Bruggeman’s model assumes that the interactions among the particles can occur according to the increase in the volume fraction of one component, which can directly influence the material thermal conductivity [ 31 , 32 ].…”

Lignosulfonate is a cheap material available in large quantities obtained as a byproduct of paper and cellulose. In this work, blends of polypropylene (PP) and sodium lignosulfonate (LGNa) were developed to evaluate the potential use of lignosulfonate as a lightweight, thermal insulation and flame retardant material. The blends were obtained by mixing in a torque rheometer and molded after compression. The blend proprieties were evaluated by physical, morphological, thermal, thermal conductivity, and flammability tests. The measured values were compared with theoretical models. The results indicated that a heterogeneous blend with a higher number of separated domains is formed when the LGNa content increases from 10 to 40 wt%. In addition, the density and thermal conductivity coefficient of the blends studied are not affected by the addition of LGNa. However, when the LGNa content in the blend exceeds 20 wt% the thermal stability and flame retardant proprieties are considerably reduced. The theoretical models based on the rule of mixtures showed a good agreement with the experimental values obtained from blend density, thermal conductivity, and thermal stability. In general, lignosulfonate tested in this work shows potential to be used as a reactive component in polymer blends.

“…Liu et al [164] adopted the same strategy and fabricated HDPE composites containing graphite-based fillers of different particle sizes. In these composites, large fillers were acting like backbones, whereas the smaller fillers represented the branches (Figure 24 potential reuse of waste in suitable applications [165].

“…Red mud mainly consists of a mixture of oxide of different metals such as iron, aluminum, silicon, titanium, and calcium with κ f of 11.7 W/(m·K). The composites with 50% volume fraction exhibited κ c of 1.4 W/(m·K), which was almost 5 times higher than pure PP, showing potential reuse of waste in suitable applications [ 165 ].

The low thermal conductivity of polymers is a barrier to their use in applications requiring high thermal conductivity such as electronic packaging, heat exchangers, and thermal management devices. Polyolefins represent about 55 percent of global thermoplastic production, and therefore improving their thermal conductivity is essential for many applications. This review analyzes the advances in enhancing the thermal conductivity of polyolefin composites. First, the mechanisms of thermal transport in polyolefin composites and the key parameters that govern conductive heat transfer through the interface between the matrix and the filler are discussed. Then the advantage with different thermally conductive fillers are reviewed and analyzed. Finally, the key challenges and future directions for developing thermally enhanced polyolefin composites are outlined.

“…102 Kucukdogan et al performed theoretical and experimental investigation on RM-filled polymer composites for thermal conductivity coefficient (TCC) evaluation and reported that for up to 50 wt% of RM addition, the TCC value increases for polymer composites. 103 The influence of RM surface treatment on PMMA-RM composite and PVC-RM composite are analyzed in terms of improvement in thermal stability. The TGA and TMA results concluded that acid-treated PMMA-RM composite has better CTE than untreated and basic treated composites due to better improvements of dispersion properties resulting from an increase in the specific surface area.…”

Industrial wastes such as marble dust, fly ash, and red mud have progressed as an environmental hazard that needs to be disposed or utilized for minimizing the ecological pollution problems and manufacturing costs. Over the years, there is an increasing interest among researchers in utilizing these industrial wastes as reinforcement for developing economic and lightweight monolithic or hybrid composites. In the same context, this paper presents a comprehensive review on the aspects of tribology and thermal performance of industrial waste such as marble dust, fly ash, and red mud as reinforcement for different monolithic and hybrid composites. The review also describes different applications for industrial waste material reinforced composites. Finally, the paper concludes with authors’ perspective of the review, conclusion summary, and future potential of industrial waste filled composites in different industries for obtaining a sustainable and cleaner environment.
