In-situ preparation of novel nanocomposites of PMMA and ordered mesoporous carbon (FDU-15)

Ordered mesoporous carbons have recently been in significant attention because of their unique hexagonal structure, tunable large pore volumes, high thermal stability, and surface-to-volume ratio. In this research paper, for achieving the maximum compatibility between FDU-15 poly(methyl methacrylate) (PMMA), 3-aminopropyltriethoxysilane (KH-550) was used as a modifying coupling agent to facilitate bond formations carbon PMMA with help ultrasonic irradiation. Nanocomposite (NC) films were produced via in-situ polymerization method aligned various amounts modified FDU-15. Sample characterizations done by field-emission scanning electron microscopy (FE-SEM), low angle X-ray diffraction (LXRD), Fourier transform infrared spectroscopy, transmission (TEM), thermogravimetric analysis (TGA). The LXRD pattern proved that structure preserved NCs, however, intensities reflexes long range order decreased. PMMA-m-FDU 2 wt% showed existence some pores on its surface according FE-SEM. TEM images NC depicted well-ordered arrays matrix perpendicular axis confirmed 2D mesopores. TGA data also m-FDU-15 increases into matrix, higher stability will achieve. Also, Td increase temperatures. highest resistant among other studied NCs.
