FTIRpolyethylene terephthalateHe~+ ionchemical damageThe degradation induced by MeV He+ ions onto polyethylene terephthalate (PET) is investigated as a function of fluence and electronic stopping power (dE/dx)e. Stack samples of four 3.6μm PET films are irradiated by 3.5MeV He+ under vacuum ...
Crystallinity is another important parameter to predict the extent of biodeterioration of the polymer, measured with the help of Differential Scanning Calorimetry (DSC) and FTIR analysis. Generally, the amorphous region is easily accessible and degraded by microorganisms, resulting in an initial increase ...
The experimental device used is the tubular kiln, coupled to an analyzer Fourier Transform Infrared (FTIR) and a Non Dispersive Infrared analyzer (NDIR). Temperatures are considered between 800 and 1000掳C. Local concentrations of oxygen during thermal degradation are 0%, 10% and 21%. On the ...
The FTIR spectra of BCD and active films in comparison with control are presented in Fig. 1. BCD showed the strong peaks in the band at 3399.94 to 3231.33 cm−1, which is related to the O–H stretch. The prominent peaks in the band at 1421.19 and 1282.07 cm−1 also related to O...
The total IR reflectance of the coated nanoporous Ag film was measured using a Fourier transform infrared spectrometer (FTIR) equipped with a diffuse gold integrating sphere (Fig. 2a). The coated nanoporous Ag film shows a high IR reflectivity of 98.5% (weighted over human body radiation), whic...

An integrated thermogravimetric/Fourier transform infrared (TGA/FTIR) system is used to detect the presence of a fatty acid in a commercial, photodegradable, polyethylene concentrate. This technique is simple, rapid, convenient, and requires minimal sample manipulation. It can be very useful for monit...

The amount of diphosphite on the surface of the film was determined by Fourier Transform Infra Red (FTIR) absorption. A peak at 835 am−1was used for the diphosphite sold under the trademark Doverphos 9228. The apparent rate of diffusion through different types of linear ethylene copolymer ...
