Description
Summary:In this work, oxidized carbon nitride (O-C 3 N 4 ) nanoparticles were obtained by oxidizing the graphitized carbon nitride (C 3 N 4 ) nanoparticles, which were used to improve the mechanical properties and thermal stability of epoxy resin. The crystal structure, morphology and chemical structure of C 3 N 4 and O-C 3 N 4 were characterized by X-ray diffraction, scanning electron microscopy and Fourier infrared spectroscopy, respectively. Which ensures that they were prepared successfully. In order to compare the reinforcing effect of C 3 N 4 and O-C 3 N 4 , they were dispersed in epoxy resin as fillers, respectively. The results show that the optimum content of C 3 N 4 and O-C 3 N 4 was 0.3 Phr and 0.5 Phr, respectively. The tensile strength of the composites was increased by 17% and 24% compare to the pure epoxy, respectively. Meanwhile, the impact toughness was increased by 63% and 180%, respectively.
