In this study, a film was prepared from polyvinyl alcohol (PVA) and zinc oxide (ZnO) nanoparticles (nano-ZnO) via the casting method. Nanoparticles were added to PVA biopolymer to create reinforced biocomposite films with different loading contents (2, 4, and 6 wt.%), and they were tested by performing the following assays: the FTIR test, the antib...

In this work, a polymeric blend of polypropylene (PP) and high-density polyethylene (HDPE) was prepared with different weight percentages. Zinc oxide nanoparticles (ZnO) were added to the 90/10 and 80/20 blends with different weight ratios (1%, 2%, and 3%) to study their effect on both the mechanical and thermal properties of the PP/HDPE blends. A...

Article history: Abstract: Received 20 th November 2023 The aim of this research is to study the effect of incorporating PVC and chopped glass fibers (CGF) on the mechanical properties of butyl rubber composites. In this study, PVC and CGF were employed as fillers in a rubber pastry formulation composed of 100% butyl rubber. To study the effect of...

The purpose of this studying is to investigation of the mechanical characteristics of the rubber tires before and after consumption. A new and old car tires were used and three samples from each tire were used to prepare the samples [tensile strength, hardness, and wear]. When the sample is examined, it's found that the tire before use had a tensil...

Received Nowadays it is difficult to imagine life without nano-technologies, more specific: nanomaterials. The purpose of this review article is to highlight the definition, types and the application of both nano-materials and nano-composites. Different types of nanocomposites materials with different application are exist based on their matrix and...

Slipping agents Polypropylene Beeswax Talc Stearamide FTIR DSC Rheological properties In the present work, the effect of three different types of slipping agents (beeswax, stearamide, and talc at the nanoscale) on the mechanical, tribological, and rheological properties of polypropylene PP has been investigated. An extruder with a twin screw was us...

In this research, four novel types of hyperbranched polyester polymers (HBPs) were used and blended with polypropylene polymer PP, virgin VPP and recycled rPP, using a twin-screw extrusion machine. Hyperbranched polyester was added in different weight ratios (5%, 10%, and 20%). The Fourier transform spectroscopy FTIR, the water contact angle CA, th...

Compared to linear analogs, hyperbranched polymers (HBPs) have gotten much attention in the last decade because of their intrinsic globular topologies and distinctive features like low viscosity, high solubility, and a high degree of functionality. In this work, four types of hyperbranched polyester polymer HBPs have been synthesized using the A2+B...

Shear thickening fluids STFs are a new kind of materials that consist of nano/micro particles that dispersed in another material such as polymer. In this review paper, the definition of this type of materials and the mechanism of its work are explained. In addition, the main factors that can effect on this behavior and their applications in differe...

In this work, a new hyperbranched polyester polymer (HBP) was prepared by using A2+B3 polycondensation polymerization methodology and blended with polypropylene PP. Both Nuclear magnetic resonance (NMR) and Fourier transform spectroscopy (FTIR) were used to characterize the HBP. The prepared HBP was blended with polypropylene (PP) in different weig...

The purpose of this review article is to highlight the various approaches for measuring polymer degradation. Different tests (mechanical, thermal, rheological) give good evidence about polymer properties. From these tests, the effect of varying degradation factors on the general properties of the polymer can be estimated. Change in weight, thermal...

Purpose: Low density polyethylene is commonly used polymer in the industry because of its unique structure and excellent overall performance. LDPE, is relatively low mechanical properties and thermal stability can sometimes limit its application in industry. Therefore, the development of particulate reinforced polymer composites is one of the highl...

Mixing two polymers usually results in an immiscible system, characterized by a coarse, easy to alter morphology, and poor adhesion between the phases. These blends have large size domains of dispersed phase and poor adhesion between them. Therefore, miscibility of polymer blend must be improved by using suitable additives such as compatibilizer. I...

Mixing two types of polymers usually results in an immiscible blend, especially when using polymers with different polarities; therefore, a compatibilization process using suitable compatibilizers to improve miscibility is required. In this work, a low-density polyethylene (LDPE)/poly vinyl alcohol (PVA) blend was improved by adding maleic acid as...

Natural rubber-graphite composites (0, 1, 2, 3, 4 pphr graphite) were prepared on a laboratory two-roll mill. Swelling measurements were used to evaluate the impacts of graphite on the properties of natural rubber. Swelling results showed that the volume fraction of natural rubber in the swollen gel, the interaction parameter, and the cross-link de...
