摘要: High modulus and thermal stability of polyimide (PI)/reactive halloysite nanotubes (HNTs) nanocomposites were prepared by in situ polymerization. The pristine HNTs firstly handled with the tetraethoxysilane (TEOS) secondly grafted silane agent. fourier transform infrared spectroscopy (FTIR) approved that TEOS was beneficial for agent to modify HNTs. Scanning electron microscopy (SEM) showed differences morphology between reactive PI/reactive exhibited lower moisture absorption than pure polyimide. reduced transmittance nanocomposites. Significant improvements glass transition temperature (Tg) achieved addition only a small amount It noteworthy both tensile strength Young' significantly enhanced. A 62.8 % increase 63.7 3 wt.% achieved. Finally, preparation mechanism obtain proposed.
