Polymer composites filled with metal derivatives have been widely used in recent years, particularly as flame retardants, due to their superior characteristics, including high thermal behavior, low environmental degradation, and good fire resistance. The hybridization of metal and polymer composites produces various favorable properties, making them ideal materials for various advanced applications. The fire resistance performance of polymer composites can be enhanced by increasing the combustion capability of composite materials through the inclusion of metallic fireproof materials to protect the composites. The final properties of the metal-filled thermoplastic composites depend on several factors, including pore shape and distribution and morphology of metal particles. For example, fire safety equipment uses polyester thermoplastic and antimony sources with halogenated additives. The use of metals as additives in composites has captured the attention of researchers worldwide due to safety concern in consideration of people’s life and public properties. This review establishes the state-of-art flame resistance properties of metals/polymer composites for numerous industrial applications.

Polymer Composites Filled with Metal Derivatives: A Review of Flame Retardants.

Investigation of the effect of water absorption on thermomechanical and viscoelastic properties of flax-hemp-reinforced hybrid composite

The development of antimicrobial packaging has been growing rapidly due to an increase in awareness and demands for sustainable active packaging that could preserve the quality and prolong the shelf life of foods and products. The addition of highly efficient antibacterial nanoparticles, antifungals, and antioxidants to biodegradable and environmentally friendly green polymers has become a significant advancement trend for the packaging evolution. Impregnation of antimicrobial agents into the packaging film is essential for impeding or destroying the pathogenic microorganisms causing food illness and deterioration. Higher safety and quality as well as an extended shelf life of sustainable active packaging desired by the industry are further enhanced by applying the different types of antimicrobial packaging systems. Antimicrobial packaging not only can offer a wide range of advantages, but also preserves the environment through usage of renewable and biodegradable polymers instead of common synthetic polymers, thus reducing plastic pollution generated by humankind. This review intended to provide a summary of current trends and applications of antimicrobial, biodegradable films in the packaging industry as well as the innovation of nanotechnology to increase efficiency of novel, bio-based packaging systems.

The research work has focused on identifying the influence of pulsed gas metal arc welding (PGMAW) parameters on the austenitic stainless steel (ASS) weld bead on high-strength low-alloy (HSLA) steel plate. The effect of pulse parameters such as dimensionless factor (ϕ), mean current (Im), and heat input (Ω) has been analyzed on the thermal behavior of weld, weld pool geometry, and the weld bead microstructure. The influence of ϕ on the thermal and metal transfer behaviors has been also examined to produce the desired weld bead quality. The optimized pulse parameters such as Im (160–230 A), Ω (6.5–11.2 kJ/cm), ϕ (0.05–0.25), and welding speed (S) (15–25 cm/min) have been considered to perform the experiment. The microstructural evaluation of the weld bead was carried out by an optical microscope. The enhanced Im from 160 A to 230 A considerably increased the amount of temperature received by the weld pool (QT) from 4525 to 6525 J/S. The results also depicted that the increase of ϕ from 0.05 to 0.25 predominantly reduced the width of the weld bead (Wb) from 15 to 13.5 mm, depth of penetration (Pd) from 3.5 to 2.5 mm, and area of fusion (Af) from 40 to 30 mm2, respectively. It is also found that the formation of fine-grain microstructure in the weld deposit primarily happened due to the effect of thermal behaviors such as QT, transfer of heat content from filler to weld pool (Qf), and characteristics of filler metal transfer to the weld deposition.
