IR spectrum of MFTIR - fibrous material - polyethylene terephthalate - triacetateWe investigated the influence exerted by the conditions of preparation of specimens of fibrous materials made of polyethylene terephthalate and triacetate threads and fabrics and the conditions of recording IR spectra of ...
Spectra of the four plastics were obtained with a resolution of 4 cm-1averaging five scans with a total acquisition time of approximately 15 seconds for each spectrum. The biodegradable bag sample was identified (using the spectral library) as high-density polyethylene (HDPE) with a 94% match,...
Effect of surface pretreatment of TiO2 films on interfacial processes leading to bacterial inactivation in the dark and under light irradiation Evidence is presented for radio-frequency plasma pretreatment enhancing the amount and adhesion of TiO2 sputtered on polyester (PES) and on polyethylene (P......
The fine-structure of the 720/730 cm -1 doublet of FTIR spectra has been evaluated by derivative spectroscopy as function of temperature on low-density poly(ethylene-co-1-octene). The pseudo-hexagonal mesophase in polyethylene, obtained at atmospheric pressure, is a non-equilibrium phase which ...
