Abstract:

The paper presents electrospinning technology used for the production of polymer nanofi- brous mats. Surface properties of polymer nanofibrous mats electrospun from poly (vinylidene fluoride) (PVDF) and poly (vinyl chloride) (PVC), and modified in dielectric barrier discharge (DBD) are presented. The contact angle of the polymer mats un-modified and modified in DBD generated plasma were compared. The plasma modification decreased the contact angle for water from 134° to 40°, for PVDF, and close to zero in the case of PVC. It was also observed that the contact angle decreased with an increase in the discharge power and discharge time, leading to an improvement of adhesion properties of the mat.
