By integrating the design of high-performance material with solid structural design, flexible pavement performance can be increased and the service life extended. In the context of creating highways the topic of asphalt polymer modification and the incorporation of polymers in asphalt material by mechanical mixing or chemical reaction, has received substantial scholarly coverage. A wide range of polymers types are used in the method of changing asphalt material and subsequently enhancing hot mixed asphalt. The main objective of this paper is to review prior research on employing polymer materials to develop the qualities of asphalt cement and hot mixed asphalt. This study reviews three different types of polymers. These polymers are Styrene-butadiene-styrene (SBS), polytetrafluoroethylene (PTFE), and polyvinyl chloride polymers (PVC). According to earlier studies in this area, these polymers are elastomers and plastomers that are utilized to enhance the mechanical properties of hot-mix asphalt while also increasing the stability, elasticity, and stiffness of asphalt binders. The overall performance of asphalt pavement can be achieved by reducing the possibility of rutting in the summer and cracking in the winter.

High-performance commodity polymers are in demand due to low cost, durability, easy productivity, and recycling ability. This article comprises a survey on the performance properties of polytetrafluoroethylene (PTFE) fluoropolymer. It is a well-known choice for coatings, insulation, thermal sealing, lubrication, bearings, and clinical applications. PTFE was engineered in many forms as a function of loading nano and micro fillers for different purposes and the improved properties and performance were addressed by the researchers. Hence, we disclosed the various casting routes of PTFE which is feasible for reliable processing to serve in domestic and industrial applications.

The Development of New Nanocomposite Polytetrafluoroethylene/Fe2O3 NPs to Prevent Bacterial Contamination in Meat Industry

et al. 2022

The bacterial contamination of cutting boards and other equipment in the meat processing industry is one of the key reasons for reducing the shelf life and consumer properties of products. There are two ways to solve this problem. The first option is to create coatings with increased strength in order to prevent the formation of micro damages that are favorable for bacterial growth. The second possibility is to create materials with antimicrobial properties. The use of polytetrafluoroethylene (PTFE) coatings with the addition of metal oxide nanoparticles will allow to the achieving of both strength and bacteriostatic effects at the same time. In the present study, a new coating based on PTFE and Fe2O3 nanoparticles was developed. Fe2O3 nanoparticles were synthesized by laser ablation in water and transferred into acetone using the developed procedures. An acetone-based colloidal solution was mixed with a PTFE-based varnish. Composites with concentrations of Fe2O3 nanoparticles from 0.001–0.1% were synthesized. We studied the effect of the obtained material on the generation of ROS (hydrogen peroxide and hydroxyl radicals), 8-oxoguanine, and long-lived active forms of proteins. It was found that PTFE did not affect the generation of all the studied compounds, and the addition of Fe2O3 nanoparticles increased the generation of H2O2 and hydroxyl radicals by up to 6 and 7 times, respectively. The generation of 8-oxoguanine and long-lived reactive protein species in the presence of PTFE/Fe2O3 NPs at 0.1% increased by 2 and 3 times, respectively. The bacteriostatic and cytotoxic effects of the developed material were studied. PTFE with the addition of Fe2O3 nanoparticles, at a concentration of 0.001% or more, inhibited the growth of E. coli by 2–5 times compared to the control or PTFE without NPs. At the same time, PTFE, even with the addition of 0.1% Fe2O3 nanoparticles, did not significantly impact the survival of eukaryotic cells. It was assumed that the resulting composite material could be used to cover cutting boards and other polymeric surfaces in the meat processing industry.
