In this paper, the effect of unmodified halloysite nanotubes (HNTs) content on the chemical structure and the thermal and mechanical properties of blends based on starch-grafted-polyethylene (SgP) and high density polyethylene (HDPE) (70/30 w/w) nanocomposites was investigated at various filler content ratios, i.e. 1.5, 3 and 5 wt.%. The study showed the occurrence of chemical interactions between the polymer matrix and HNTs through OH bonding. Further, the addition of HNTs to the polymer blend led to an increase in the crystallization temperature of the nanocomposite samples, in particular at higher filler contents i.e. 3 and 5 wt.%, while the melting temperature remained almost unchanged. Tensile and flexural properties of the nanocomposite samples were however improved compared to the virgin blend with respect to the HNTs content ratio.

In this study, recycled coffee gunny (RCG) was used to reinforce high density polyethylene (HDPE). Maleic anhydride grafted polyethylene (MAPE) was added as a compatibilizer. Moreover, the RCG was chemically treated to enhance the compatibility between fiber and HDPE matrix. A series of RCG reinforced composites were prepared and the effects of MAPE and chemical modification of RCG on the mechanical and thermal properties of HDPE were investigated. The results of thermal and mechanical properties of composites revealed that the increments of heat deflection temperature, tensile strength, and impact strength of HDPE were 16[Formula: see text]C, 19.64% and 43.63% by the addition of modified coffee gunny, respectively. It reveals that the HDPE was reinforced with the coffee gunny, and thus can effectively reuse the discarded resources.

Organic filler like carbon black (CB) and inorganic filler like talc (T) with 0, 0.5, 1.0, 10, 20 and 40 wt% were separately loaded in high density polyethylene (HDPE) by the extrusion moulding method at 160oC. Then, different sets of filler loaded HDPE composites were prepared using the compression moulding technique, and their structures and mechanical properties were characterized. The pure HDPE sample, as examined by the X-ray diffraction (XRD) technique, showed orthorhombic structure, which did not change either with filler types or with their concentration. The only variations found in the structure are the changes of crystallinity and crystallized size that depend on both types of fillers and their concentrations. Incorporation of CB in HDPE emphasizes the crystallinity and crystallized size more than that of T. The tensile strength of the composite decreases with the increase of both types of fillers, and this decrease is explained on the basis of Nielson model, which basically describes a poor interaction between filler and HDPE matrix. An increase of Young’s modulus of 350% is observed with the increasing CB and T contents, representing an increase of the stiffness in the materials. Flexural strength increased with the increase of CB content but decreased with the increase of talc content. Although the microhardness was observed to increase with both types of fillers, the hardness value was 80% higher for CB loaded-composites than that of T at 40 wt% filler content. These findings strongly indicate that the compatibility of HDPE is better with organic filler than with inorganic one.

The effects of compatibilizer (maleic anhydride-graft-polyethylene) on the mechanical properties of pineapple leaf powder (PALP) filled high density polyethylene (HDPE) composites were studied. HDPE and PALP composites in the presence, or absence of the compatibilizer, maleic anhydride -graft- polyethylene (MA-g-PE) were prepared by injection moulding technique. The filler (PALP) contents investigated were 2, 4, 6, 8, and 10 wt%, while the MA-g-PE content was 3 wt% of the filler content for each formulation. The result of the mechanical tests carried out on the HDPE/PALP composites showed that the tensile strength, tensile modulus, abrasion resistance, and hardness of the composites increased as the filler content increases both in the presence, or absence of the compatibilizer (MA-g-PE) for all the filler contents investigated, while the elongation at break (EB) for PALP/HDPE composites was found to decrease as the filler content increases both in the presence, or absence of MA-g-PE for all the filler contents investigated. It was also observed that PALP/HDPE composites in the presence of MA-g-PE exhibited better mechanical properties than that of PALP/HDPE composites in the absence of MA-g-PE for all the filler contents investigated. The present study has proved that the mechanical properties of PALP/HDPE composites can be enhanced by incorporating a compatibilizer (MA-g-PE) into their formulations. This is so because the chemical composition of the compatibilizer (MA-g-PE) allows it to react with the fibre surface, thereby forming a bridge of chemical bonds between the fibre and matrix.
