“…There are four spectrum sections in the mid-infrared region: the fingerprint region (400-1500 cm -1 ), the double bond region (1500-2000 cm -1 ), the triple bond region (2000-2500 cm -1 ), and the X-H stretching region (2500-4000 cm -1 ). The FTIR operator uses the signals that emerge in these to identify most molecular structures, functional groups, and organic bonds by comparing them to the infrared correlation chart [15,16].…”

Polyester based particle reinforced composites were developed using varying weight fractions (ranging from 0 to 30 wt%, at 5 wt% interval) of microcrystalline wood charcoal powder (75µm). Quantitative, qualitative and functional characterization of developed wood charcoal (WC) particles reinforced polyester matrix composites was carried out successfully using energy dispersive x-ray spectrophotometer (EDXRF), Fourier transform infrared spectrometer (FTIR) and scanning electron microscope (SEM) enhanced with ancillary EDS for elemental identification capability. The primary elements and oxides identified in wood charcoal by EDXRF include iron, copper, zinc, calcium and CaO, Fe2O3, CuO, ZnO respectively. These elements and oxides were noted to induce improvement on the properties of reinforced polymer composites. EDS elemental mapping also confirmed the major elements identified by EDXRF analysis. Composites reinforced with microcrystalline wood charcoal exhibited strong interfacial bonding and interlocking due to even dispersion of the filler particles as revealed by SEM images. Interactions of the microcrystalline wood charcoal fillers with the polyester matrix molecules were revealed by FTIR functional characterization as minor shifts in the frequency bands of functional groups normally present in unsaturated polyester resin.
