In order to effect organic bonding in the organic functional groups in OSP, pellet-mode Fourier transform infrared (FT-IR) spectrometry was utilized for samples with 90 wt% KBr and 10 wt% OSP. In order to determine the thermal mass loss of OSP, thermogravimetric (TG) analysis/derivative thermogravimetric analysis (dTG) curves were recorded within the 60–1000 ◦C temperature range at a rate of 10 ◦C/min by a TG analyzer (TGA; Shinco, TGA-N1000, USA).
