Fourier Transform Infrared Spectroscopy : Low Density Polyethylene, High Density Polyethylene, Polypropylene and Polystyrene Eman Mousa Alhajji North Carolina State University Department of Materials Science and Engineering MSE 255 Lab Report 203. A. Patrick Snyder 3/13/2016. Abstract The objectives of this experiment are to analyze the vibrational properties and Fourier Transform Infrared Spectroscopy (FTIR) measurements of four polymers assigned to unknown spectra, examine how different bonds and functional groups give rise to different FTIR signatures and estimate % crystallinity in LDPE and HDPE as semi-crystalline polymers. FTIR spectrum of sample A was identified to relate to PP molecular structure with two functional groups: methyl and methylene. The FTIR spectrum of sample A was identified to relate to PS molecular structure with two functional groups, methylene and Phenyl.
Mar 13, 2016 · Fourier transform infrared spectroscopy (FTIR) is a method used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high spectral resolution data over a wide spectral range. 1 Figure 1 shows the typical arrangement of FTIR.
