“…On the other hand, it is possible to produce fibrous polypropylene materials from the melt by electrospinning [ 2 , 3 , 4 , 5 , 7 , 8 , 9 , 12 , 13 , 14 ], melt-blowing [ 1 , 15 ], centrifugal spinning [ 16 ] or by combining several of these methods [ 17 ]. Moreover, nonwovens can be produced, not only from polypropylene homopolymers, but also from its copolymers [ 18 ] and blends with other polymers [ 19 , 20 , 21 ].…”

Nowadays, polypropylene-based nonwovens are used in many areas, from filtration to medicine. One of the methods for obtaining such materials is melt electrospinning. In some cases, it is especially interesting to produce composite fibers with a high degree of filling. In this work, the influence of the filling degree of isotactic polypropylene with calcium carbonate on the structure and properties of nonwoven materials obtained by melt electrospinning was studied. It was shown that electrospinning is possible, even at a filler content of 50%, while the average diameter of the fibers increases with the growth in the content of calcium carbonate. The addition of sodium stearate significantly reduces the diameter of the fibers (from 10–65 to 2–10 microns) due to reducing viscosity and increasing the electrical conductivity of the melt. Wide-angle X-ray diffraction analysis and IR spectroscopy reveal that the initial polymer and composites are characterized by the presence of stable α-form crystals, while nonwovens show a predominance of smectic mesophase. The addition of calcium carbonate leads to an increase in the hydrophobicity of the composite films, the addition of sodium stearate results in a decrease of hydrophobicity, while all nonwovens demonstrate superhydrophobic properties.

“…As the strain increased (0–100% ε), the randomly arranged nanofibers started to deform and orientate along the loading direction. More importantly, neighboring fibers constituted interconnective nets via bonding points, and the net-like structure could transfer and dissipate the loaded force effectively, contributing to the high tensile strength. , A further increment of tensile strain (200% ε) would stretch the aligned nanofibers into thinner fibers. Consequently, the very thin fibers between bonding points in the network structure started to fracture, while some unbonded fibers slipped apart, resulting in the breakage of nanofiber membranes, as schematically demonstrated in Figure e.…”

Seawater desalination is a promising and sustainable solution to alleviate freshwater scarcity; however, most existing desalination membranes suffer from poor channel interconnectivity and toxic solvent processing and encounter a tradeoff dilemma of salt rejection and water flux. Herein, we report a unique and facile one-step green solvent/nonsolvent spinning methodology to assemble environmentally friendly polyamide nanofiber membranes with a precisely designed interconnective/stable channel structure and surface anti-wettability for seawater desalination. Direct electrospinning without any post-treatments via in situ introduction of fluorinated chemicals enables highly interconnective amphiphobic channels within polyamide membranes, and the incorporation of nonsolvent (diacetone alcohol) into polyamide/solvent (ethanol) spinning solutions endows the green alcohol-based polyamide membranes with a stable bonding structure and small pore size. The resultant green solvent/nonsolvent-spun polyamide nanofiber membranes show impressive liquid entry pressure (120.5 kPa) and vapor permeation (12.5 kg m–2 d–1), achieving robust seawater desalination performance with a salt rejection of 99.97% and permeate flux of 47.4 kg m–2 h–1. The facile one-step solvent/nonsolvent spinning strategy, highly interconnective amphiphobic channels, and green solvent-based environmental friendliness in this work can open opportunities for future polyamide membranes for practical applications in water purification.

“…Liquid protection is another essential aspect of barrier clothing for everyone, not just employees. Jinhao et al [ 143 ] fabricated a novel melted polyvinyl butyral (PVB) bonded PP composite fibrous mat, where PVB and PP were mixed at different percentages to increase the structural stability and mechanical properties of a pristine PP fibrous mat system. The mechanical properties, including tensile stress, and tearing strength of composite fibrous mats were improved significantly due to the bonding between PVB and PP molecules in the fiber.…”

Polyolefins are a widely accepted commodity polymer made from olefinic monomer consisting of carbon and hydrogen. This thermoplastic polymeric material is formed through reactive double bonds of olefins by the addition polymerization technique and it possesses a diverse range of unique features for a large variety of applications. Among the various types, polyethylene and polypropylene are the prominent classes of polyolefins that can be crafted and manipulated into diversified products for numerous applications. Research on polyolefins has boomed tremendously in recent times owing to the abundance of raw materials, low cost, lightweight, high chemical resistance, diverse functionalities, and outstanding physical characteristics. Polyolefins have also evidenced their potentiality as a fiber in micro to nanoscale and emerged as a fascinating material for widespread high-performance use. This review aims to provide an elucidation of the breakthroughs in polyolefins, namely as fibers, filaments, and yarns, and their applications in many domains such as medicine, body armor, and load-bearing industries. Moreover, the development of electrospun polyolefin nanofibers employing cutting-edge techniques and their prospective utilization in filtration, biomedical engineering, protective textiles, and lithium-ion batteries has been illustrated meticulously. Besides, this review delineates the challenges associated with the formation of polyolefin nanofiber using different techniques and critically analyzes overcoming the difficulties in forming functional nanofibers for the innovative field of applications.
