Description
Summary:[Display omitted] ► No need of pre or post electrospinning treatment for the reduction of AgNO 3 solution into Ag NPs. ► Electrospinning solvents is used as a reducing agent for the conversion of AgNO 3 into Ag NPs during the solution preparation. ► Ag NPs size could be controlled by regulating the standing time duration of electrospinning solution. A facile one-step approach to fabricate nylon-6 nanofibers decorated with silver nanoparticles by electrospinning has been reported. The method did not need post-treatments and could be carried out at ambient room condition. It employed the electrospinning solvents [formic acid and methoxy poly(ethylene glycol)] as a reducing agent for the conversion of AgNO 3 into Ag NPs during the solution preparation for electrospinning. The resultant Ag/nylon-6 hybrid nanofibers showed a smooth fibrous structure, with controlled size of Ag NPs uniformly dispersed throughout the nylon-6 matrix. The size of Ag NPs could be controlled by regulating the standing time duration of electrospinning solution. These hybrid nylon-6 composite nanofibers exhibited antibacterial activity against both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus. Therefore, the obtained nylon-6 nanofibrous mats loaded with Ag NPs can be used in different areas such as wound dressing, water filters etc.
