The purpose of the paper is to obtain and examine the structure and properties obtained in the electrostatic field of micro- and nanofibers PCL. Design/methodology/approach: The main problem of the study is to examine the impact of properties of the polymer solutions PCL obtained from the mixture of formic acid and acetic acid in a ratio of 70:30, tetrahydrofuran and dimethylsulfoxide in a ratio of 70:30, and chloroform and methanol in a ratio of 70:30 on the structure and and surface properties of polymer micro and nanofibers PCL. Findings: On the basis of out carried researches the impact of the polymer solutions applied to researches on the diameter and the properties of obtained polymer micro- and nanofibers have been shown. It comes out that from the our carried researches of specific surface area of fibers the highest specific surface area BET was obtained for fibers formed from a mixture of acetic acid and formic acid and it is equalled 8.9 m2/g. Significantly smaller surface area was obtained from a mixture of tetrahydrofuran and dimethyl sulfoxide 3.1 m2/g. However, the lowest surface area for fibers obtained from a mixture of chloroform and methanol, which is 0.9 m2/g, in spite of the observation of the porous surface of fibers. Practical implications: Mixture of formic acid and acetic acid may be an alternative solution for preparing nanofibers PCL. Originality/value: The results confirm the possibility of receiving nanofibers PCL from a mixture of non-toxic solvents.
