Antimicrobial PVDF nanofiber composites with the ZnO - vermiculite - chlorhexidine based nanoparticles and their tensile properties
Original language description
The PVDF nanofiber materials with antimicrobial zinc oxide (ZnO), zinc oxide/vermiculite (ZnO/V), zinc oxide/vermiculite-chlorhexidine (ZnO/V_CH) and vermiculite-chlorhexidine (V_CH) nanofillers were electrospun via one-step electrospinning process. The PVDF nanofiber diameters and their orientation were investigated using scanning electron microscope (SEM). The ZnO/V_CH and V/CH nanofillers with positive Zeta - potential values were incorporated into PVDF nanofibers with an average diameter of 108 nm for PVDF_ZnO/V_CH and 100 nm for PVDF_V_CH samples. In contrast, ZnO and ZnO/V nanofillers with negative Zeta - potential values reacted intensively with PVDF polymer. The hydrophobic character was demonstrated by water contact angle from 100o. The chemical interactions were evaluated by the Fourier transform infrared spectroscopy (FTIR). The presence of the -phase in the original PVDF and the small traces of the alfa-phase in PVD_ZnO and PVDF_ZnO/V samples was confirmed. In the PVDF_ZnO/V_CH and PVDF_V/CH samples where the specific interaction of PVDF chains with CH a rapid decrease in the beta-phase fraction was evaluated. The mechanical properties based on the Young's modulus (E) and tensile strength (Rm) values were evaluated from the tensil test curves. Antimicrobial activity (longer than 48 hours) against S. aureus and E. coli for PVDF_ZnO/V_CH and PVDF_V/CH samples was obtained.
