Fourier transform infrared spectroscopy (FTIR) (Nicolet Nexus 670, Thermo Fisher Scientific, Waltham, MA, USA) was performed for the 3D-printed PPS samples under different thermal conditions with a single-reflection attenuated total reflectance (ATR) accessory. ATR-FTIR spectra were collected at room temperature over a scanning range of 4000–600 cm−1 with a spectral resolution of 4 cm−1. The surface of FTIR test is the cross sections of 3D-printed samples under different thermal conditions.
