Article Title: Electroless Deposition for Robust and Uniform Copper Nanoparticles on Electrospun Polyacrylonitrile (PAN) Microfiltration Membranes

doi: 10.3390/membranes14090198

Figure Lengend Snippet: FTIR spectra of the electrospun PAN mats after electroless deposition with fiber sizes of ( top ) 232 nm, ( middle ) 727 nm, and ( lower ) 1017 nm. The intense peak at 1609 cm −1 observed for all metallized fibers is indicative of the cyclization of the nitrile functional groups, a feature linked to enhanced adhesion between metallic nanoparticles and PAN fibers.

Article Snippet: Polymer chemistry was investigated using Fourier transform infrared spectroscopy (FTIR) (ARCoptix, Neuchatel, Switzerland), performed using Perkin Elmer IR 100 spectrometer (Perkin Elmer, Shelton, CT, USA) operated in transmittance mode and spanning wavenumbers from 4000 to 500 cm −1 at room conditions.
