“…Other than that, GO has a vast amount of oxygen functional groups where the exothermal energy from the decomposition of GO enhances the decomposition temperature of the ABS matrix. Similar observations have been reported by [32,33]. Ref.…”

In this study, acrylonitrile butadiene styrene (ABS)/talc/graphene oxide/SEBS-g-MAH (ABS/Talc/GO/SEBS-g-MAH) and acrylonitrile butadiene styrene/graphene oxide/SEBS-g-MAH (ABS/GO/SEBS-g-MAH) composites were isolated with varying graphene oxide (0.5 to 2.0 phr) as a filler and SEBS-g-MAH as a compatibilizer (4 to 8 phr), with an ABS:talc ratio of 90:10 by percentage. The influences of graphene oxide and SEBS-g-MAH loading in ABS/talc composites were determined on the mechanical and thermal properties of the composites. It was found that the incorporation of talc reduces the stiffness of composites. The analyses of mechanical and thermal properties of composites revealed that the inclusion of graphene oxide as a filler and SEBS-g-MAH as a compatibilizer in the ABS polymer matrix significantly improved the mechanical and thermal properties. ABS/talc was prepared through melt mixing to study the fusion characteristic. The mechanical properties showed an increase of 30%, 15%, and 90% in tensile strength (TS), flexural strength (FS), and flexural modulus (FM), respectively. The impact strength (IS) resulted in comparable properties to ABS, and it was better than the ABS/talc composite due to the influence of talc in the composite that stiffens and reduces the extensibility of plastic. The incorporation of GO and SEBS-g-MA also shows a relatively higher thermal stability in both composites with and without talc. The finding of the present study reveals that the graphene oxide and SEBS-g-MAH could be utilized as a filler and a compatibilizer in ABS/talc composites to enhance the thermo-mechanical stability because of the superior interfacial adhesion between the matrix and filler.

“…Ref. [33] quoted that the increase in thermal stability was attributed to the inhibition of polymer segment mobility at the interphase of the matrix and filler. This inhibition occurs because of the strong interaction between the polymer and the matrix.…”

“…The surface activity, particle size, surface area, and surface functional groups of talc can influence its performance. [23] Talc has been used as a reinforcing filler in PP at high concentrations and has been shown to be highly dependent on the PP matrix composition and talc surface treatment. [24] 30 wt% talc in the composite did not exhibit a considerable increase on tensile strength (7% increase compared to neat PP Y).…”

Hybrid cellulose‐inorganic reinforcement polypropylene composites: Lightweight materials for automotive applications

et al. 2019

Cellulose fibers are attracting considerable attention within the transportation industry as a class of reinforcing agents for polymer composites owing to their low cost, low density, high mechanical properties, and considerable environmental benefits. The objective of this study was to develop hybrid composites combining cellulose fiber with long glass fiber (LGF), short glass fiber (SGF), or talc in a polypropylene (PP) matrix to optimize the overall composite properties. Tensile, flexural, and notched Izod impact tests revealed that in general the mechanical properties decreased with increasing cellulose content, however, adding an optimum concentration of the cellulose fiber is a promising alternative to reduce or replace the utilization of inorganic fibers. Hybrid composites with 15 wt% LGF and 15 wt% Cellulose A exhibited an increase of 86% and 252% in tensile stress and Young's modulus, respectively, compared to neat PP X. Regarding the impact strength and the temperature at the maximum rate of decomposition, hybrid composites with 15 wt% SGF and 15 wt% Cellulose B exhibited 23% and 17% increase, respectively, compared to neat PP Z. The crystallization temperature (Tc) of all the composites increased compared to neat PP, revealing the fibers ability to act as nucleating agents and speed rate of part production which will result in lowering the manufacturing cost. For applications in automotive “under‐the‐hood” and body interior components, the hybrid cellulose‐inorganic reinforcement composite approach not only leads to superior weight and cost savings, but also environment benefits over the inorganic reinforced composites.

“…Talc is another commonly used inorganic filler. At high loadings (10-40 wt%), talc acts as rigid particles to increase the stiffness and Young's modulus of the plastic, but causes a reduction in the elongation at break and impact strength [212]. This was observed by Wang et al [213], who injection moulded PP with talc at 10 and 20 wt% loading.…”

Polyolefins and Polyethylene Terephthalate Package Wastes: Recycling and Use in Composites

et al. 2021

View full text Add to dashboard Cite

Plastics are versatile materials used in a variety of sectors that have seen a rapid increase in their global production. Millions of tonnes of plastic wastes are generated each year, which puts pressure on plastic waste management methods to prevent their accumulation within the environment. Recycling is an attractive disposal method and aids the initiative of a circular plastic economy, but recycling still has challenges to overcome. This review starts with an overview of the current European recycling strategies for solid plastic waste and the challenges faced. Emphasis lies on the recycling of polyolefins (POs) and polyethylene terephthalate (PET) which are found in plastic packaging, as packaging contributes a signification proportion to solid plastic wastes. Both sections, the recycling of POs and PET, discuss the sources of wastes, chemical and mechanical recycling, effects of recycling on the material properties, strategies to improve the performance of recycled POs and PET, and finally the applications of recycled POs and PET. The review concludes with a discussion of the future potential and opportunities of recycled POs and PET.
