C properties, it truly is evident that the nanofibrous structure of supplies reduces the relative permittivity. Pure PDVF had about two instances higher relative MCC950 Protocol permittivity than mixed PVDF/PA6 material. The presence of atmospheric air in between the fibers in the DNQX disodium salt Protocol material also contributed to lowering the relative permittivity on the material. The loss of the d33 coefficient on the PVDF/PA6 mix was also confirmed. Its worth was up to 3 occasions less than pure PVDF. Variation of PVDF and PA6 makes it possible for the material to obtain very demanded structural (phase composition, crystallinity) and functional (mechanical, electrical) properties. On the other hand, mixing reduced the relative permittivity and in all probability decreased the -phase content material. On the other hand, the material nonetheless retained an general higher content material of and -phase, making it suitable for triboelectric and piezoelectric applications. The material requires to be additional optimized and studied for future sensible applications. The described results may perhaps bring new possibilities for the use of mixed PVDF/PA6 as an very easily modifiable, cheap and accessible material for textile applications and nanogenerators.Author Contributions: Conceptualization, P.C. and T.P.; methodology, N.P.; application, N.P.; valida tion, D.S., J.K. and P.S.; formal analysis, K.C.; investigation, P.C. and T.P.; resources, K.C. and P.S.; information curation, N.P. and D.S.; writing–original draft preparation, P.C., T.P., N.P. and R.M.; writing–review and editing, T.P.; visualization, N.P. and P.C; supervision, D.S.; project administration, S.T.; funding acquisition, S.T.
