Due to the demand from society for the consumption of ecological
polymeric materials, one of the polymers that have satisfied this request is
the poly (lactic acid) (PLA). This polymer
is derived from renewable resources, it is recyclable and biodegradable. It
presents a good understanding between the promising properties and the cost.
However, a route to increase the mechanical properties and reduce the
cost of PLA is the elaboration of PLA based biocomposites by using fillers from
natural waste. In this work, The effect of Typha content on the morphological, rheological, thermal and mechanical properties of
PLA matrix was studied. Four formulations were produced with different mass
concentrations. The results showed an increase in the viscoelastic properties,
as a function of the Typha stem powder concentration.
The DSC analysis showed an increase in the crystallinity rate of the various
composites confirming the nucleating effect provided by the filler. TGA
analysis indicated a decrease in the decomposition temperature of the
composites. Mechanical tensile tests have shown a significant improvement in
the mechanical properties mainly for the samples containing 45% (w/w) of Typha powder.
