“…Figure 2E is a scheme in which the technique is carried out without a capillary tube but using an electrically charged rotatory cylinder and a solution reservoir. In this case, the rotating cylinder is partially submerged in the solution, and the formed fibers are deposited in the static but grounded collector [14].…”

The air is a fundamental element for the life on Earth. Rapid urbanization and industrialization release large amounts of pollutants (harmful gases, microorganisms, and particulate matter, among others) into the atmosphere, leading to health hazards. Air filtration is still the most used and promising technique for protecting air against pollutants. The quality and efficiency of filtering process are dependent of material used for the filter and other filter’s properties. Several methods can be used for manufacturing filters, one of them uses fibrous membranes obtained through electrospinning from polymeric solutions. Electrospinning is a technique that combines the application of an electrostatic field to a moving fluid which results in the fibers formation. Electrospun membranes are constituted by fibers that the sizes spread on submicro and or nanometric scales. This review focuses on fiber membranes obtained by electrospinning for filtration of particulate matter. It is addressed the effect of solution, processing and ambient parameters on the morphology and dimensional characteristics of fiber membranes. The basic principles of air filtration and test and characterization of filter performance are presented. The research progress on electrospun nanofibers as air filters in recent years is summarized and examined. Finally, conclusion and future perspectives in electrospun fibers for air filtration are provided and discussed.

“…The electrospinning technique has been increasingly exploited, especially in the last two decades, in order to produce continuous, uniform polymer fibers with a high area/volume ratio and diameters at the micro-and nanometric scales [1]. This technique presents a relatively simple and inexpensive yet highly versatile experimental apparatus.…”

Comparative analysis of electrospun PNIPAAm blends with some biodegradable polymers

In this work, electrospun fibers of poly(butylene adipate-co-terephthalate)/poly(N-isopropylacrylamide), PBAT /PNIPAAm, and ecovio ® /PNIPAAm blends were obtained. These blends presented a thermoresponsive behavior including a sudden response to temperature variation between 32 and 35 ºC. The addition of PNIPAAm to PBAT and ecovio ® solutions significantly improved the electrospinability of both solutions as blends, allowing them to form rounded fibers without defects and with diameters varying between 1000 and 1700 nm. The analysis of attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) spectra for PBAT/PNIPAAm and ecovio ® /PNIPAAm electrospun fibers revealed that the electrospinning process does not lead to the formation of strong intermolecular interactions, such as hydrogen bonds, between the constituents of the studied blends' electrospun fibers. Significant drop water contact angle variation as a function of temperature was observed for both PBAT/PNIPAAm and ecovio ® /PNIPAAm electrospun fibers; both presented PNIPAAm's hydrophilic-hydrophobic transition in the range between 32 and 35 ºC. Comparing PBAT/PNIPAAm and ecovio ® /PNIPAAm electrospun fibers, the former was revealed to be more temperature-sensitive than the latter, regarding changes in wettability as the former presented larger gaps in drop water contact angle values compared to the latter. With these results, these blends in the form of electrospun fibers may have a potential application in the field of cell adhesion/detachment.

The air is a fundamental element for the life on Earth. Rapid urbanization and industrialization release large amounts of pollutants (harmful gases, microorganisms, and particulate matter, among others) into the atmosphere, leading to health hazards. Air filtration is still the most used and promising technique for protecting air against pollutants.

Several methods can be used for manufacturing filters, one of them uses fibrous membranes obtained mainly through electrospinning from polymeric solutions. Electrospinning is a technique that combines the application of an electrostatic field to a polymer solution that induces the fluid to move and, due to the solvent evaporation, results in the fibers formation. Electrospun membranes are constituted by fibers that the sizes spread on submicro and or nanometric scales.

It is addressed the effect of solution, processing, and ambient parameters on the morphology and dimensional characteristics of fiber membranes.
