Layer-by-Layer Assembled, Amphiphilic and Antibacterial Hybrid Electrospun Mat Made from Polypropylene and Chitosan Fibers

In this study, hybrid fiber mat (HFPP-CS) consisting of both chlorinated polypropylene and chitosan fibers (FPP-Cl FCS) is obtained by assembling layer-by-layer for the first time using electrospinning process. Morphological, wettability, structural thermal properties HFPP-CS are investigated in detail Scanning electron microscopy (SEM), water contact angle (WCA) measurement, fourier transform infrared spectroscopy, thermogravimetric analysis differential scanning calorimetry analyses, respectively, comparing with FPP-Cl FCS. Furthermore, antibacterial activity all samples was evaluated against to gram positive Staphylococcus aureus (S. aureus) negative Escherichia coli (E. coli) bacteria. SEM proves has a circular smooth morphology also comprises microscale nanoscale FCS layers within range 2.1–2.7 μm 175–475 nm, respectively.
