Procedures of preparation homogeneous nanofiber structures of the desired morphology1 and properties by electrospinning process and consequent exploitations in air and liquid filtration2 are presented.

Nanostructures applied in air filtration possess excellent filtration efficiency first of all in separation of ultrafine particles. Presented and compared have been the filtration properties of electrospun materials with homogenous structure in the whole manufactured width 140 cm. The minimum pressure drops of these materials varied from 6 to 8 Pa only. Values of filtration efficiency are measured in accordance with requests of EN 1822 for elimination of ultrafine particles in sizes 20 through 400 nm

To evaluate the influence of chemical composition of nanofibers on filtration efficiency in MPPS (maximum penetrating particle size), the nanostructure based on polyvinylidene fluoride, polyurethane, polylactide acid and polyamide 6 have been compared...
