Nanodiamond and its Polymeric Nanocomposites, A Review

Improving mechanical, thermal and abrasion resistance of different polymer nanocomposites with nanodiamond particles have been interested for researchers in recent years. This review article is focused on nanodiamond, its production and preparation from nature briefly, synthesis and preparation of its polymer nanocomposites. In most of these nanocomposites, thermal, mechanical and abrasion resistance properties were improved by use of nanodiamond in polymer matrix. As an example: tensile strength of poly vinyl alcohol based nanocomposite with 5% nanodiamond increased from 95 MPa to 124 MPa and its tensile modulus from 3.7GPa to 10.6GPa. The tensile strength is also increased by 20% in epoxy resin/nanodiamondnanocomposites. Thermal degradation temperature of polypropylene and ethylene-propylene dien monomer elastomeric blend was increased about 46˚C by using of 5% nanodiamond in their composition. Obvious increasing in mechanical,thermal and abrasion properties were also observed forpolyurethane elastomer and rubber compoundsby applying only 1% and 3%nanodiamond respectively.
