ATR-FT-IR spectra of different fillers

ATR-FT-IR spectra were recorded using a Thermo Scientific Nicolet 6700 FT-IR spectrometer with a “Smart Orbit” diamond micro-ATR accessory in mid-IR and far-IR regions: 4000-225 cm-1 (with DLaTGS detector and CsI beamsplitter) and 500-80 cm-1 (with DTGS detector with PE window and Solid Substrate far-IR beamsplitter).
