“…Both the surface and the interior of PS fibers could have porous structures by determining a suitable solvent ratio of THF/DMF [ 75 ]. H 2 O has also been employed as a nonsolvent to create porous structures in a PAN/DMF system [ 76 , 77 , 78 ]. Ji et al [ 79 ] constructed porous CA fibers in a highly volatile binary solvent system of DCM/DMAC.…”

Electrospun porous nanofibers have gained a lot of interest recently in various fields because of their adjustable porous structure, high specific surface area, and large number of active sites, which can further enhance the performance of materials. This paper provides an overview of the common polymers, preparation, and applications of electrospun porous nanofibers. Firstly, the polymers commonly used to construct porous structures and the main pore-forming methods in porous nanofibers by electrospinning, namely the template method and phase separation method, are introduced. Secondly, recent applications of electrospun porous nanofibers in air purification, water treatment, energy storage, biomedicine, food packaging, sensor, sound and wave absorption, flame retardant, and heat insulation are reviewed. Finally, the challenges and possible research directions for the future study of electrospun porous nanofibers are discussed.

This article reports the production, morphological analyzes, and application of electrospun self‐same nanocomposites with milled carbon fibers (MCFs). The new hybridized structure was also incorporated into conventional fiber reinforced epoxy composites with improved properties. The MCF‐hybridized polymeric nonwoven mats were formed with the simultaneous dual electrospinning of a soften‐able (m‐phase) and a crosslink‐able (x‐phase) variants of poly(styrene‐co‐glycidyl methacrylate). The morphology of the hybrid material was investigated using scanning electron microscopy (SEM). The results showed that electrospinning can successfully deposit reinforcing particles of giant size (MCFs are 7 μm in diameter, 50 μm to 3 mm in length) compared to the diameter of the carrier nanofibers (nanometers). The new hybrid structure preserved the fibrous morphology of the polymer phases up to 250°C. The overall morphology of the hybrid composite was tunable by changing the fractions of the two polymeric phases. The particle‐polymer hybrid structures created morphologies that might find applications in various areas such as the interlayer toughening of laminated composites. It was shown that m‐phase/MCF@x‐phase nonwoven integrated into epoxy matrix composite laminates as interlayer, increased the strain at failure and ultimate strength under tensile loading by 11% and 9%, respectively.

“…PAN nanofibrous membranes were produced in one step by electrospinning of the ternary system of PAN/DMF/H2O with phase separation mechanism, leading to fibers with an average diameter of 700-800 nm [142]. This separator membrane shows a higher air permeability value than the Celgard PP separators, leading also to hihgler porosity, interconnected pores and ionic conductivity [142].…”

Efficient energy storage systems are increasingly needed due to advances in portable electronics and transport vehicles, lithium-ion batteries standing out among the most suitable energy storage systems for a large variety of applications. In lithium-ion batteries, the porous separator membrane plays a relevant role as it is placed between the electrodes and serves as a charge transfer medium and affects the cycle behavior. Typically, porous separators membranes are comprised of a synthetic polymeric matrix embedded in the electrolyte solution.The present chapter focus on recent advances in synthetic polymers for porous separation membranes, as well as on the techniques for membrane preparation and physicochemical characterization. The main challenges to improve synthetic polymer performance for battery separator membrane applications are also discussed.
