“…Also it can be seen in Figure 2(b), that the presence of MMT helps to improve dispersion of CNTs into the HDPE matrix resulting in improved mechanical properties. For SC3 (nanocomposite with compatibilizer), tensile strength and young's modulus is enhanced by 32 % and 13 % respectively, compared to S1, similar results were also reported in literature [12]. This is due to the presence of compatibilizer further enhancing the adhesion between the fillers and polymer matrix [33].…”

“…The data presented are the average of three readings. When compared to neat polymer resin (S1), the tensile properties of S2 nanocomposite is shown to be improved by 12 % which could be attributed to the presence of CNTs that stiffen the polymer matrix resulting to significant increase in the elastic modulus of the nanocomposite [12]. Incorporation of MMT to CNT/HDPE nanocomposites (S3) further enhanced the tensile strength by 16 %.…”

“…In general, the mechanical properties of carbon nanotubes reinforced polymer do not improve significantly mainly due to the weak polymer-CNT interfacial adhesion that prevents the efficient stress transfer from the polymer matrix to CNT [6,7,10,11]. As a result, nanocomposite having properties much inferior to theoretical expectations is obtained [2,10,12]. Among the choice of polymer matrix, polyethylene is widely used due to its attractive properties.…”

“…Yang et al [20] enhanced the compatibility and dispersion of CNTs in polyethylene matrix by melt blending of amine-functionalized nanotubes with maleic anhydride modified high density polyethylene (PE-g-MA). Pollanen et al [12] enhanced the thermal and mechanical properties of HDPE by melt mixing it with CNT/PE-g-MA master batch.…”

“…low interfacial tension) between nanotubes and polymers, their compatibility has to be enhanced which can be done using different methods such as functionalizing the sidewalls of CNT [9,10,18], grafting technique [7,19] and also by addition of polymeric compatibilizer such as maleic anhydride grafted polymers [12,[20][21][22]. It is widely accepted that the polymer nanocomposites prepared with the incorporation of a compatibilizer performs better [12,22,23].…”

In this study, we have attempted to explain the influence of secondary filler on the dispersion of carbon nanotube (CNT) reinforced high density polyethylene (HDPE) nanocomposites (CNT/HDPE). In order to understand the mixed-fillers system, Montmorillonite (MMT) in addition with Maleic anhydride grafted high density polyethylene (PE-g-MA) was added to CNT/HDPE nanocomposites. It was followed by investigating their effect on the thermo-mechanical, rheological and morphological properties of the aforesaid nanocomposite. Incorporation of 3 wt% each of MMT and PE-g-MA into CNT/ HDPE nanocomposites resulted to the increased values for the tensile and flexural strength (32 % increase in both), as compared to the pure HDPE matrix. The thermal analysis result showed improved thermal stability of the formulated nanocomposites. The initial decomposition temperature (T i ) for such nanocomposite with 9 wt% of MMT and 3 wt% of PEg-MA reached to 296 o C from 265 o C (T i for neat HDPE matrix). Addition of MMT to CNT/HDPE nanocomposites also increased the rheological properties indicating a dominating elastic response. A significant increase in loss, storage modulus and complex viscosity was observed upon addition of PE-g-MA, whereas Tan δ was found to be reduced. This might be due to better interfacial adhesion between MMT and HDPE phases that attributes to the elastic dominance. Improvement in dispersion of CNT upon addition of MMT and PE-g-MA was further supported by the morphological analysis. Transmission electron microscopy (TEM) images revealed that larger aggregates of CNTs were disappeared upon addition of these two components leading to the enhancement of thermo-mechanical properties for such composites.

The effect of graphene nanoplatelets (GNPs) and titanate coupling agent on morphology and mechanical properties of high density polyethylene (HDPE) nanocomposites was investigated. The titanate has a tendency to link chemically with the two dissimilar species GNPs and HDPE via proton coordination to generate a complete continuous phase for stress/strain transfer via the elimination of air voids and hydrophobicity. The interaction of titanate with GNPs and HDPE was effective to improve the dispersion of GNPs in HDPE composites. At constant weight (1 wt %) of titanate treatment for 2 and 5 wt % HDPE composites, we clearly observed a significantly high value of tensile strength and elongation at break than untreated composites. Particularly, composite containing 2 wt % GNPs in HDPE with titanate showed 66.5% improvement of the ultimate tensile strength and an enormously high value of elongation at break. The effect of GNPs dispersion and orientation in HDPE for the mechanical reinforcement was also evaluated based on the experimental modulus data to theoretical predictions made using the Halpin‐Tsai model. © 2015 Wiley Periodicals, Inc.
