Popis: New types of HDPE/LLDPE/OMMT nanocomposites, which were used as packaging materials, were prepared by direct injection moulding without any compatibiliser. This method was similar to the film forming technology. TEM observation revealed that the OMMT layers were homogeneously dispersed throughout the matrix at the nano-scale. The results of mechanical properties measurement showed that the tensile strength, tensile modulus, flexural strength and flexural modulus were improved remarkably with small amounts of OMMT, whose contents were below 6.0 wt.%. For example, the yield strength of the nanocomposite with 4.0 wt.% OMMT was 32.8 MPa, which increased 27.6% compared with that of the neat sample. Meanwhile, the heat deflection temperature values and TGA results showed that the thermal stability also improved.
