Zinc oxide nanoparticle kenaf polyester composite (ZnONPs/kenaf/polyester)
containing 1, 2, 3 and 4 layers of kenaf fibre treated with 40nm 2% (w/w) and 5 % (w/w ) of
ZnONPs were prepared and characterised to evaluate the mechanical and thermal properties.
The composites were prepared based on 4 kenaf layers and 2%, 5% (w/w) ZnONPs
concentrations, all the samples were compared with control systems containing zero kenaf fibre
and untreated with ZnONPs to save as references. The composites were fabricated using cold
mixed blend via compression sandwich mould technique. The composites with 1 layer 5%
(w/w) ZnONPs treated had the lower tensile strength and lower modulus suggesting it higher
flexibility compared with those systems containing high number of layers, similar trend were
seen in 2% (w/w) treated ZnONPs concentrations. The mechanical properties of composites
containing 5% (w/w) ZnONPs demonstrated that the addition of fibre layers to the
ZnONPs[kenaf/polyester was affected more than the 2% (w/w). While thermogravimetric
analysis of 5% (w/w) and 2% kenaf composites incorporated with 1 and 4 layers were equally
compared. The (5%) ZnONPs/kenaf/polyester treated revealed no significant changes in the
decomposition temperature and showed no thermal transitions, this suggesting that it is nonbiodegradable. Both results of the mechanical and thermal properties test suggest that the 1%
(w/w) provide the based mechanical and thermal stable composite with novel biodegradability.
