With the people’s awareness of the “3Rs” in recent years, using recycled high-density polyethylene (HDPE) and random copolymer polypropylene (PPR) as the base materials for piping fabrication has become a mainstream in scholastic path and industrial engineering. In this study, the modified maleic anhydride-grafted polyethylene (POE-g-MAH) compatibilizer was fabricated to increase the interfacial adhesion and dispersion. With the surface modification of calcium carbonate, a POE-g-MAH/CaCO3/HDPE polymer composite has been prepared. Such modified polymer composites can further reinforce the processing performance and mechanical properties of recycled HDPE and PPR materials. The results indicated that with the introduction of the polymer composite, significant enhancement of the recycled materials in the aspects of processability, tensile strength, flexural performance, and impact force could be obtained, and the POE-g-MAH/CaCO3/HDPE polymer composite would contribute to the impressive balance between high rigidity and toughness. In addition, the feasibility and mechanical properties of the recycled HDPE-PPR-POE-g-MAH/CaCO3/HDPE blended system were also studied: with the help of a composite microcapsule, the gap of mechanical capacity between recycled and non-recycled materials was further reduced, and such a blended system was capable of being commercialized in the piping industry.

The present study explains the preparation of high-density polyethylene (HDPE)-based nanocomposites containing different amounts of montmorillonite (MMT) nanoclay (1–10 wt%). These nanocomposites were obtained by melt blending in a co-rotating twin screw extruder in absence and presence of a compatibiliser (HDPE-g-MA). The melt rheological behaviour of HDPE/MMT nanocomposites has been investigated by using capillary rheometer at 190°C, 200°C and 210°C over the shear rate range of 50–1000 s−1. The melt viscosity of HDPE increased marginally at 10 wt% filler loading while addition of compatibiliser to HDPE/MMT composites did not show any significant effect on viscosity. All nanocomposites showed shear thinning and non-Newtonian flow behaviour. The power law index reduced with increase in MMT concentration and increased with increase in temperature while opposite trend was observed for the consistency index. The activation energy was highest for the nanocomposites containing 10 wt% MMT and decreased upon addition of coupling agent.

Influence of clay nanofillers on properties of ethylene‐octene copolymers

The article deals with preparation, properties and usage of ethylene-octene copolymers/clay films. Different properties of two types of ethylene-octene copolymers (Engage 8540 and Engage 8842) with 17 and 45 wt% of octene (EOC-17 and EOC-45) were compared in nanocomposites with two types of clays-Cloisite 93A and Dellite 67. The aim was to evaluate the influence of (nano)filler type on ethylene-octene nanocomposites properties. Mechanical and thermal properties, morphology, and UV radiation degradation were observed. Furthermore, permeability of three different gasses was determined. EOC nanocomposites perform a higher elongation at break, especially EOC-45. Dynamic Mechanical Analysis (DMA) showed an increase of E 0 modulus of all nanocomposites in a wide range of temperatures compared to pure EOC. Intercalation of nanofillers was studied by transmission electron microscopy (TEM) and X-ray diffraction (XRD). It has been proved that EOC-45 has a better dispersion EOC-17. DSC analysis showed a shift in a crystallization temperature for EOC-17, where the nanofiller acted as a nucleation agent due to the worse dispersion. Barrier properties were improved by almost 100% by addition of organoclay for all measured gasses; they were best for EOC-17 nanocomposites due to a higher crystallinity. XRD together with transmission electron microscopy (TEM) showed much better dispersion for EOC-45 nanocomposites. Fourier transform infrared spectroscopy (FTIR) and accelerated UV aging showed C@O peaks for EOC nanocomposites. POLYM. COMPOS., 00:000-000, FIG. 3. DMA graphs temperature dependencies: EOC-17 (Engage 8540) with 5% Cloisite 93 and Dellite 67, EOC-45 (Engage 8842) with 5% Cloisite 93 and Dellite 67: (a) E 0 modulus, (b) tan d.
