“…No chemical reaction occurred between LDPE and PBS due to the absence of any new peak. The results were consistent with the HDPE/PBS/HDPE–g–MA blends according to El-Rafey et al [ 29 ].…”

“…This might be attributed to strong interfacial adhesion as well as improved dispersion of PBS particles with the incorporation of PE–g–MA, resulting in better stress transfer among the matrix and the dispersed phase of the studied system [ 38 ]. The same effect was observed for HDPE/PBS blends with the incorporation of PE–g–MA [ 29 ]. They further explained that the increased TS was related to the physical interaction between MA groups on PE–g–MA and with hydroxyl and carboxyl groups of PBS and that physical entanglement exists among the PE chains in the PE–g–MA and LDPE matrix chains.…”

“…The primary drawback of combining LDPE with PBS is the poor of miscibility, since PBS is a polar polymer, which has oxygen-based groups and ester groups in its structure, whereas LDPE is a non-polar polymer. As a result, the poor interfacial adhesion among them causes inferior mechanical properties [ 29 ]. In fact, incompatibility in polymer blends leads to unstable morphology and weak mechanical properties, whereas compatibility in polymer blends demonstrates good properties [ 30 ].…”

Blending of Low-Density Polyethylene and Poly(Butylene Succinate) (LDPE/PBS) with Polyethylene–Graft–Maleic Anhydride (PE–g–MA) as a Compatibilizer on the Phase Morphology, Mechanical and Thermal Properties

It is of significant concern that the buildup of non-biodegradable plastic waste in the environment may result in long-term issues with the environment, the economy and waste management. In this study, low-density polyethylene (LDPE) was compounded with different contents of poly(butylene succinate) (PBS) at 10–50 wt.%, to evaluate the potential of replacing commercial plastics with a biodegradable renewable polymer, PBS for packaging applications. The morphological, mechanical and thermal properties of the LDPE/PBS blends were examined in relation to the effect of polyethylene–graft–maleic anhydride (PE–g–MA) as a compatibilizer. LDPE/PBS/PE–g–MA blends were fabricated via the melt blending method using an internal mixer and then were compression molded into test samples. The presence of LDPE, PBS and PE–g–MA individually in the matrix for each blend presented physical interaction between the constituents, as shown by Fourier-transform infrared spectroscopy (FTIR). The morphology of LDPE/PBS/PE–g–MA blends showed improved compatibility and homogeneity between the LDPE matrix and PBS phase. Compatibilized LDPE/PBS blends showed an improvement in the tensile strength, with 5 phr of compatibilizer providing the optimal content. The thermal stability of LDPE/PBS blends decreased with higher PBS content and the thermal stability of compatibilized blends was higher in contrast to the uncompatibilized blends. Therefore, our research demonstrated that the partial substitution of LDPE with a biodegradable PBS and the incorporation of the PE–g–MA compatibilizer could develop an innovative blend with improved structural, mechanical and thermal properties.

Poly(vinyl chloride) (PVC) nanocomposites with different contents of copper alumina (Cu-Al 2 O 3 ) nanoparticles were prepared by the solution casting method.The effects of the nanoparticles on structural, thermal, electrical, contact angle and mechanical properties were thoroughly examined. The presence of Cu-Al 2 O 3 in the macromolecular chain was confirmed through Fourier transform infrared (FTIR) spectroscopy. The X-ray diffraction (XRD) analysis of PVC nanocomposites showed the systematic arrangement of Cu-Al 2 O 3 nanoparticles within the polymer, which indicated the higher crystallinity of the nanocomposites. The surface morphology of PVC was changed into hemispherical shaped particles by the inclusion of nanofiller was analyzed from SEM images. The glass transition temperature of the nanocomposites obtained from differential scanning calorimetry (DSC) was found to be increased with an increase in loading of nanoparticles in the polymer. The AC conductivity and dielectric studies revealed that the inclusion of nanofiller increases the electrical properties of the material and the composite with 7 wt.% sample showed the maximum conductivity and dielectric constant. The mechanical properties such as modulus, tensile strength, hardness, and impact properties of the PVC nanocomposites were significantly enhanced by the reinforcement of nanoparticles into the PVC matrix. The reinforcing mechanism behind the increase in tensile strength with the addition of nanoparticles was correlated with different theoretical models. The highest mechanical and electrical properties were observed for 7 wt.% Cu-Al 2 O 3 loaded nanocomposite. Contact angle measurements of PVC with various loadings of Cu-Al 2 O 3 nanofillers demonstrated that the nanoparticle attachment increased the hydrophobicity of the polymer matrix.conductivity, contact angle, copper alumina, dielectric properties, mechanical properties, nanocomposites, PVC Polyvinyl chloride (PVC) is one of the high-strength thermoplastic polymers with paramount chemical stability, durability, formulating versatility, corrosion resistance, and cost-effectiveness that make them potent candidates for automotive, construction and electronic applications such as flooring, bottles, pipes, indwelling catheters, fittings, and food packing.

“…Polymers are used in day-to-day life, namely, rubber, plastic, and resins and are labeled in accordance to their origin, such as natural rubber and silk, starch, semisynthetic modified polymers, cellulosic compounds, and synthetic ones (polyolefins, polystyrene, polyesters, polyethers, and PVC). − PVC is used in pipes, electric powered wires, window profiles, etc. It has proper mechanical properties, fire and fungus opposing and lengthy lifetime. − PVC produced by cracking from petroleum or natural gas bears a randomly disbursed molecular weight with a degree of viscosity with some additives that govern its physical, thermal, and mechanical characters and improve cost, processability, durability, weather resistance, color, and electrical performance. − Heat stabilizers like tribasic PbSO 4 and lead compounds increase thermal degradation concerning PVC, discoloration, and decay of both mechanical and chemical properties. Processing aids like methyl methacrylate (MMA) encourage the melt flow during manufacturing and improve the transparent look.…”

As a filler to be inserted into poly(vinyl chloride) (PVC), low-cost olive pits flour (OPF) and precipitated bio-calcium carbonate (PBCC)-produced PVC/OPF/PBCC composites have been used with high stability and rigidity compared to PVC. Hydrogen bonding is generated between OH cellulose in OPF and H in PVC. Composite tensile modulus increased in PVC grid in the presence of PBCC and OPF, possibly because of a filler restriction effect on the polymer chains. The hardness also increased as both OPF and PBCC increased. The mechanical tendency of the PVC/ OPF composite was improved by adding a low content of PBCC particles with the PVC network, resulting in a smart distribution in the range of 10% by weight, and it was reduced by adding more than that percentage. The successful distribution of PBCC in PVC/OPF composite strengthened the mechanical path. The morphology and possible interface adhesion of components in the composite were demonstrated by scanning electron microscopy (SEM). The PVC SEM images showed a homogeneous, smart, and consistent surface, while the PVC/60 wt % OPF SEM images showed a large number of voids that suggested weak PVC/OPF interactions. The SEM images showed outstanding PBCC distribution in the PVC/OPF matrix for the PVC/50 wt % OPF/10 wt % PBCC composite. Due to the accumulation of PBCC particles producing cavities, the distribution of particles became nonhomogeneous at percentages above 10 wt %. At a low filler material, better spread of PBCC particles in the PVC grid was achieved. Owing to the polarity of OPF, the H 2 O absorption and thickness swelling of PVC/OPF/PBCC composites showed higher amounts than PVC. PBCC improved the thermal stabilization and the neutralization of Cl − negative ions as an acid acceptor of secondary PVC stabilization.
