Improved Strength and Heat Distortion Temperature of Emi-Aromatic Polyamide 10T-co-1012 (PA10T/1012)/GO Composites via In Situ Polymerization

Abstract: In this paper, an effective method for preparing poly (p-phenylene terephthalamide) -co- poly (dodecanedioyl) decylamine (PA10T/1012)/graphene oxide (GO) composites by pre-dispersion and one-step in situ polymerization was proposed for the first time. During the process of polycondensation, the condensation between the terminal amino groups of PA10T/1012 chains and the oxygen-containing functional groups of GO allowed nylon to be grafted onto graphene sheets. The effects of polymer grafting on the thermal and … Show more

“…Additionally, the peaks observed at 1291 cm −1 are assigned to the CN stretching vibration (amide III), which is present in all samples. Furthermore, the out‐of‐plane vibrations of CH on the benzene ring are detected at 866 and 721 cm −1 in both PA10T and PA10T‐FM composites 22 . Therefore, these FT‐IR characteristic peaks of amide bonds can be observed in the FT‐IR spectra of all samples, demonstrating the successful synthesis of polyamide.…”

“…Furthermore, the out-of-plane vibrations of C H on the benzene ring are detected at 866 and 721 cm À1 in both PA10T and PA10T-FM composites. 22 Therefore, these FT-IR characteristic peaks of amide bonds can be observed in the FT-IR spectra of all samples, demonstrating the successful synthesis of polyamide. Moreover, these results confirm that the PA10T and PA10T-FM composites have been effectively created, and neither MoS 2 nor PFA has an influence on the chemical bonding structure of PA10T.…”

“…It can be seen that the HDT of the POM/TPU/MLGN composites increase with the increase of MLGN mass fraction, increasing by 4.1 ℃ at 2% MLGN mass fraction, and 6.1 ℃ at 4% MLGN mass fraction. The reason may be that there is a strong interface interaction between MLGN and polymer, which limits the thermal motion of POM chain segment, thus improving the heat resistance [8,9]. Figure 5 shows the influence of MLGN content on the dielectric constant (ε r ) of POM/TPU/MLGN composites.…”
