Mechanical properties and apatite forming ability of TiO2 nanoparticles/high density polyethylene composite: Effect of filler content

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.

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 Youngs 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.

This article discusses the possibilities of using radiation cross-linked high density polyethylene (HDPEx) acting as a filler in the original high density polyethylene (HDPE) matrix. The newly created composite is one of the possible answers to questions relating to the processing of radiation cross-linked thermoplastics. Radiation cross-linked networking is—nowadays, a commonly used technology that can significantly modify the properties of many types of thermoplastics. This paper describes the influence of the concentration of filler, in the form of grit or powder obtained by the grinding/milling of products/industrial waste from radiation cross-linked high density polyethylene (rHDPEx) on the mechanical and processing properties and the composite structure. It was determined that, by varying the concentration of the filler, it is possible to influence the mechanical behaviour of the composite. The mechanical properties of the new composite—measured at room temperature, are generally comparable or better than the same properties of the original thermoplastic. This creates very good assumptions for the effective and economically acceptable, processing of high density polyethylene (rHDPEx) waste. Its processability however, is limited; it can be processed by injection moulding up to 60 wt %.

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.
