英文摘要 | The silane coupling agent (KH550) was applied to modify the surface of MCM-41 and then the nitrogen absorption-desorption, Fourier transform infrared spectroscopy (FTIR) and small angel X-ray diffraction (XRD) were used to investigate the MCM-41 before and after modification. The results show that the KH550 molecules were introduced into the rianopores of MCM-41, and the -NH2 group was grafted on the nanopore surface of MCM-41 particles. Besides, the gel permeation chromatography (GPC) was used to measure the epoxy relative molecular mass. The in situ method was used to cure epoxy composite with different KH550 modified MCM-41 contents. After that, the MCM-41/EP composite was measured by different tests, including positron annihilation lifetime spectroscopy (PALS) which was applied to measure the composite free volume, and the TEM, dynamic mechanical analysis (DMA) and alternate current (AC) breakdown test were used to indicate the composite macroscopic propertes. The TEM result shows that MCM-41 could be dispersed well in epoxy at contents lower than 1. 5% while agglomerate at 2. 5% content. The PALS results show that the epoxy molecules were introduced into and partly occupied the mesoporous channels by the applied force and functional effect of KH550. Then, an organic-inorganic interpenetrating network nanocomposite system could be formed. Therefore the glass transition temperature (15. 1% up arrow) and breakdown strength (22. 6% up arrow) of the composites were improved at low MCM-41 contents. |
