| 中文摘要 | organically modified montmorillonites (ommts) by octadecylammonium chloride with two adsorption levels were dispersed in polyamide 12 (pa12) matrices with two molecular weights for different melt mixing times in order to investigate morphology evolutions and factors influencing fabrication of pa12 nanocomposites. different adsorption levels of the modifier in the ommts provide different environments for diffusion of polymer chains and different attractions between mmt layers. wide-angle x-ray diffraction (waxd), transmission electron microscope (tem) and gas permeability were used to characterize morphologies of the nanocomposites. both ommts can be exfoliated in the pa12 matrix with higher molecular weight, but only ommt with lower adsorption level can be exfoliated in the pa12 matrix with lower molecular weight. it was attributed to the differences in the levels of shear stress and molecular diffusion in the nanocomposites. the exfoliation of ommt platelets results from a combination of molecular diffusion and shear. after intercalation of pa12 into interlayer of ommt in the initial period of mixing, further dispersion of ommts in pa12 matrices is controlled by a slippage process of mmt layers during fabricating pa12 nanocomposites with exfoliated structure. |
