Free download of FTIR spectra of basic polymer types (page bottom) The FTIR polymer spectra are available as pictures. The FTIR Spectra of following polymers were collected in transmission, range 4000-400 cm-1. Polystyrene Polyethylene Polypropylene Polyvinylchloride Teflon Poly(vinyl acetate) Poly(vi...
Use of FTIR in polymeric thin filmsFeichen YangFTIR(Fourier transform infrared spectroscopy) is a technique that uses Fourier transform to convert the raw data of infrared absorption or transmission into a infrared spectrum. Essentially, it measures the energies that are correspondent to the vibration...
FTIR(Fourier transform infrared spectroscopy) is a technique that uses Fourier transform to convert the raw data of infrared absorption or transmission into a infrared spectrum. Essentially, it measures the energies that are correspondent to the vibration of atoms in molecules or macro-molecules. The...

A background reference spectrum was first recorded, using identical parameters to the particles undergoing analysis. A blank area of the Anodisc filter was chosen as the site for background collection before immediate analysis of the sample particles. μFTIR parameters were; spectral range of 4000–...
FTIR-ATR spectra of wood samples with low (L), medium (M) and high (H) lignin contents in the finger-print region. Each spectrum is the mean of three replicate samples. ATR-FTIR spectra were converted to transmission spectra by automatic correction for the wavenumber-dependent influence on ...
Approximately 4 g of neutralized and dried polyol was weighed and placed in a polypropylene container on a stable surface. The measured isocyanate was added to the polyol in a cylindrical container with a dimension of 60 mm × 120 mm (diameter × height) using a syringe. The surfactant was ...
polypropylene (MAgPP) to fabricate the composite samples with 25% (weight percentage). MA content was optimized to 9 wt.% as recommended by the manufacturer (Merck, Germany). The notation of raw and treated jute fibers with their chemical concentrations (wt.%) in the reinforced polymeric ...
The IR spectrum of polypropylene polymer confirmed the total destruction of isotactic arrangements of the polymer. The destruction of the polypropylene polymer lead to the formation of alcoholic and ketonic groups. For polyacetate polymer, elimination of carbon dioxide took place due to destruction o...
