Surface Functionalization of Nylon 6 Nanofibers by Thermal Evaporated Silver Thin Films and Antibacterial Performance

摘要

Nylon 6 nanofibers were produced using the forcespinning® method and were collected as multilayer structures with different grams per square meters on square frames. A high vacuum thermal evaporation technique was used for surface functionalization of the nanofibers with silver thin films. The changes in surface composition, morphology and surface energy of native and metallic coated Nylon 6 nanofibers were examined by X-ray diffraction, scanning electron microscopy, scanning transmission electron microscopy and contact angle analysis. The behavior and antibacterial properties of native and silver coated Nylon 6 nanofibers were tested against Escherichia coli, Salmonella enterica serovar typhimurium, and Staphylococcus aureus.
