Air pollution is one of the major global problems causing around 7 million dead per year. In fact, a connection between infectious disease transmission, including COVID‐19, and air pollution has been proved: COVID‐19 consequences on human health are found to be more severe in areas characterized by high levels of particulate matter (PM). Therefore, after the COVID‐19 pandemic, the production of air filtration devices with high filtration efficiency has gained more and more attention. Herein, a review of the post‐COVID‐19 pandemic progress in nanofibrous polymeric membranes for air filtration is provided. First, a brief discussion on the different types of filtration mechanism and the key parameters of air filtration is proposed. The materials recently used for the production of nanofibrous filter membranes are presented, distinguishing between non‐biodegradable polymeric materials and biodegradable ones. Subsequently, production technique proposed for the fabrication of nanofibrous membranes, i.e., electrospinning and solution blow spinning, are presented aiming to analyze and compare filtration efficiency, pressure drop, reusability and durability of the different polymeric system processed with different techniques. Finally, present challenges and future perspectives of nanofibrous polymeric membranes for air filtration are discussed with a particular emphasis on strategies to produce greener and more performant devices.

“…The possibility of using food waste biomass as a filler in polymer composites is gaining interest due to a number of interesting properties such as, e.g., biodegradability, high toughness, strength, thermal stability, low density, low cost, nonabrasive to processing equipment, CO 2 neutrality when burned, and higher water resistance. − Incorporating waste or biomass fillers into a polymer matrix reduces the amount of polymer required in the composite, reducing the material cost, especially when bio-based polymers are replaced, since they are significantly more expensive than fossil-based polymers. , These materials are also abundantly available since, even though some waste and byproducts are used as raw materials for value-added bioprocessing, the great majority is currently landfilled. − The use of food waste biomass fillers in sodium alginate packaging films, to the author’s best knowledge, has yet to be investigated, and the primary bio-based filler used in alginate film composites is cellulose. ,,, …”

This paper reports the formulation of novel thermoprocessable alginate biopolymer composites filled with algae biomass or biomass waste side streams from the food industry. Plasticized alginates have classically been prepared by solvent casting from an aqueous solution. In the formulation that we report, substantially lower amounts of water are used to plasticize the alginate and make it temporarily thermoprocessable, while a permanent plasticizer (glycerol) is employed to control the final properties of the biopolymer composites after processing. Different bio-based wastes from food production were exploited as fillers (seagrass, apple pomace, and lignocellulosic side stream from different steps of the brewery process). The materials, the matrix, and its composites are processed by extrusion. Extrusion with a low water content results in a stiff material with Young′s modulus of 4 GPa and a tensile strength of 103 MPa, surpassing some of the currently used thermoprocessable bio-based and petroleum-based plastics. The addition of lignocellulosic biomass fillers brought a reduction of 28% in shrinkage and 7% in density, without significantly compromising the high stiffness of the alginate matrix. Further emphasizing the sustainable potentials, the developed materials showed to be recyclable up to 4 times without affecting the mechanical properties when the temporary plasticizer was reintroduced in the formulation.

Thermoplastic composites are broadly used in many industries. Excellent mechanical characteristics are frequently required to achieve the appropriate properties for the applications. Therefore, the objectives of this study were (1) presenting an in‐depth analysis of the effects of styrene butadiene styrene (SBS) and halloysite nanotubes (HNTs) on the tensile and fracture properties of the thermoplastic composites based on acrylonitrile butadiene styrene (ABS), and (2) examining the relationship between the microstructure of the thermoplastic composites and their mechanical behavior. For these purposes, HNTs were utilized with four levels (0, 1, 3, and 5 wt%) and SBS was used with two levels (15 and 30 wt%). The tensile strength and modulus were reduced by adding SBS to 30 wt%; however, the elongation at break was increased by 30%. Furthermore, tensile strength and modulus, and elongation at break were improved by increasing HNTs up to 3 wt%. The results indicated the elastic work (we) and plastic work (βwp) rose by 29% and 10%, respectively, when 30 wt% of SBS was added to ABS. Furthermore, we and βwp rose by the addition of HNTs up to 3 wt%. To examine fracture mechanisms, field emission scanning electron microscope (FESEM) images of the fracture surface of the essential work of fracture (EWF) specimens were taken. Several voids are present in the compounds containing SBS, activating the plastic deformation mechanism. Based on the optimization process, the best strength, stiffness, and toughness balance was attained for the compound consisting of 15 wt% SBS and 1 wt% HNTs.Highlights The effects of HNTs and SBS on the fracture properties of polymer composites. The addition of SBS increased we, βwp, and the elongation at break. HNTs had a positive effect on the tensile strength and modulus, we, and βwp. The important mechanisms include plastic deformation and cavitation.
