Influence of hematite nanorods on the mechanical properties of epoxy resin

Popis výsledku v původním jazyce

Mechanical properties of nanocomposites, obtained by incorporation of fairly uniform hematite nanorods (.alpha.-Fe2O3 NRs) into epoxy resin, were stu-died as a function of the content of inorganic phase. Thorough microstructural characterization of .alpha.-Fe2O3 NRs and nanocomposites was performed using transmission electron microscopy (TEM) and atomic force microscopy (AFM). TEM measurements revealed rod-like morphology of nano-filler with uniform size distribution (8.5 nm×170 nm, diameter×length). High-magnification TEM and AFM measurements indicated agglomeration of .alpha.-Fe2O3 NRs embedded in epoxy resin. Stress at break, strain at break, elastic modulus and tensile tough-ness of nanocomposites, were compared with the data obtained for pure epoxy resin. Significant influence of nano-filler on the mechanical properties of epoxy resin, as well as on the glass transition temperature can be noticed for samples with low content of inorganic phase (up to 1 wt. %).
