Nylon 6 nanofibre membranes were prepared by electrospinning of nylon 6 solutions with various volume ratios of trifluoroethyl alcohol (TFE) and formic acid (FA). The effect of the solvent type on the morphology of nylon 6 nanofibre membranes was investigated. Results showed that all membranes studied showed uniform, defect-free structures with very thin nanofibre diameters. The addition of formic acid led to a significant decrease in average fibre diameters. The average fibre diameters were 660, 186, 87, 62 and 30 nm for nylon 6 nonofibre prepared using the binary solution system and trifluoroethyl alcohol/formic acid (100:0), (75:25), (50:50), (25:75) & (0:100) respectively. In addition, the nylon 6 nanofibre membranes prepared using formic acid showed the highest strength with the highest porosity and the lowest average fibre diameters.

Membrany z nanowłókien Nylon 6 przygotowano przez elektroprzędzenie roztworów Nylonu 6 o różnych stosunkach objętości alkoholu trifluoroetylowego (TFE) i kwasu mrówkowego (FA). W pracy zbadano wpływ rodzaju rozpuszczalnika na morfologię membran z nanowłókien Nylon 6. Wyniki wykazały, że wszystkie badane membrany były jednolite, pozbawione wad struktury o bardzo cienkich średnicach nanowłókien. Dodatek kwasu mrówkowego doprowadził do znacznego zmniejszenia średnic włókien. Średnice nanowłókien wyniosły 660, 186, 87, 62 i 30 nm. Nanowłókna przygotowano z zastosowaniem roztworu alkoholu trifluoroetylowego i kwasu mrówkowego: 100:0; 75:25; 50:50; 25:75 i 0:100. Ponadto przygotowane przy użyciu kwasu mrówkowego membrany z nanowłókien wykazały najwyższą wytrzymałość przy największej porowatości i najniższych średnicach włókien.
