Mechanical and Thermal Properties of Polyoxymethylene Nanocomposites Filled with Different Nanofillers

The effect of the different nanofiller on properties of polyoxymethylene (POM) nanocomposites was investigated. The nanofiller containing CaCO3, Al2O3 and modified clay was used added in POM. The results showed that the Young's modulus of the nanocomposites increased after adding the nanofiller. The tensile strength and stress at break of the nanocomposites increased by adding CaCO3 nanoparticles in a range of 1-2wt.%. The addition of CaCO3 enhanced the thermal stability of the POM matrix. The microstructure of neat POM and POM nanocomposites was found that the dispersion of nanofiller particles was relatively good in a low content.
