“…PP presented the highest results when compared to the UTS among all the compositions, whereas EVA presented the lowest result. As expected for the immiscible blend system, the blends had intermediate properties between both polymers depending on their compositions, and better properties with an addictive behavior were observed to CB in comparison with B [32,35]. The incorporation of GC to the CB did not significantly change the material's UTS.…”

Polypropylene (PP)/ethylene-vinyl acetate (EVA) (60/40) blends-based glassy carbon (GC) composites with different contents of GC (0.1 to 5 wt%) were melting processed in a twin-screw extruder and the thermal, mechanical, electrical and morphological properties were evaluated to verify the effectiveness of the addition of GC as filler. Moreover, the effect of the addition of maleic anhydride grafted polypropylene (PP-g-MA) as a compatibilizer agent was also verified. The composites presented dispersed phase morphology with preferential localization of GC on interfacial regions and into the EVA phase. The mechanical properties were improved with the addition of PP-g-MA as a compatibilizer agent for the blend and the addition of GC had little influence on these properties. The results obtained from thermal properties revealed that the GC contributes to the increase in the degree of crystallinity and thermal stability of the composites. The addition of 0.1 wt% of GC increased the elastic modulus and the ultimate tensile strength without loss in the impact strength when compared to the compatibilized blend. The addition of GC increases a decade of magnitude in the electrical conductivity of the PP/EVA blends.

“…1,[6][7][8] For immiscible polymeric blends, such as PC/ABS, it is crucial to comprehend the polymeric phases interactions to understand the blend behavior, and the role of the addition of a compatibilizer agent for this system. 9,10 According to Callaghan et al, 11 the chemical compatibility between the polymeric chains of PC and styrene acrylonitrile (SAN) (from the ABS matrix) confers excellent properties to PC/ABS blends even without the addition of compatibilizer agent. 11 Nevertheless, the use of a compatibilizer agent such as maleic anhydride (MAH) grafted ABS (ABS-g-MAH), might promote thinner morphology, [12][13][14][15] higher interfacial strength, and improved interactions between the polymeric matrix and reinforcing fillers as montmorillonite 2,16 and graphene oxide (GO).…”

Polymeric blends based on polycarbonate (PC) and acrylonitrile-styrenebutadiene copolymer (ABS) are applied mainly in the electronic and automotive industries. Studies to improve the properties of PC/ABS blend have led to graphene nanoplates (GNP) addition, a carbon nanofiller derived from graphite that presents some of the promising properties of graphene. In this work, the effect of the addition of GNP (3 and 5 wt%) and maleic anhydride grafted ABS (ABS-g-MAH) were evaluated on the thermal, mechanical, rheological, and electromagnetic properties of PC/ABS blends (85/15), a different blend ratio of previous studies. It was verified that the GNP addition significantly increased the thermal stability of the blends. Furthermore, the mechanical tests showed that ABS-g-MAH acted as an efficient compatibilizer for the PC/ABS blends, and the GNP addition improved the Shore D hardness, the elastic modulus, and the maximum tensile strength of all compositions.Besides, it was observed an overlapping effect of the GNP and ABS-g-MAH addition on the mechanical properties of the blend. The addition of 3 wt% GNP to the PC/ABS (85/15) blend also doubled the elongation at break of the material. Furthermore, these contents resulted in a slight increase of the electromagnetic waves attenuation of 1-2 dB associated to electromagnetic waves reflection.

Rotational Molding is a plastic manufacturing process mainly implemented to produce stress free hollow products. Linear Low Density Polyethylene (LLDPE) is widely preferred as base resin for molding roto molded product, but it displays moderate value in some critical applications where strength is the major criteria. Additives can fill the gap in sustaining the necessary strength needed. In the present work, an attempt has been made to analyze the optimum percentage of coir reinforced with LLDPE for rotational molding technique to provide requisite processability for rotational molding process. Coir in its powder form is mixed at concentrations varying in the range of 3% to 20% with respect to LLDPE. In order to justify the prerequisite of processability for rotational molding, various experiments namely FTIR, MFI, rheology and thermal analysis were conducted. FTIR suggested the range of 5% to 15% wherein the significance of LLDPE and coir peaks can be observed. MFI test supported FTIR result which ended in considering 3% to 12% by weight ratio suitable in terms of flow ability. Rheological and thermal analysis subjecting to shear and heat parameter respectively, confirmed the range of 10 weight percentage of coir or below is suitable in terms of material processability. From the experimental results, it is concluded that 10% or less concentration of coir fiber in LLDPE as an optimum range of blend yielding better processability for rotational molding process.
