Tensile and thermal properties of elateriospermum tapos seed shells filled recycled polypropylene eco-composites
The effects of elateriospermum tapos seed shell (ETSS) and its chemical modification on tensile properties, morphology and thermal properties of recycled polypropylene (rPP) eco-composites were investigated. The rPP/ETSS eco-composites were prepared using Brabender EC-PLUS at 180°C temperature an...

| description |
The effects of elateriospermum tapos seed shell (ETSS) and its chemical modification
on tensile properties, morphology and thermal properties of recycled polypropylene
(rPP) eco-composites were investigated. The rPP/ETSS eco-composites were prepared
using Brabender EC-PLUS at 180°C temperature and rotor speed 50 rpm. Three types
of chemical modification were used; maleic acid (MA), polydimethylsiloxane (PDMS)
and organosolv lignin (OSL). It was found that the addition of ETSS in rPP ecocomposites
have decreased the tensile strength, elongation at break and degree of
crystallinity of the eco-composites. The modulus of elasticity and thermal stability of
eco-composites increased with increasing of ETSS content but the elongation at break
was significantly dropped. Morphology study of eco-composites showed the poor
interaction between ETSS filler and rPP matrix. The chemical modification of ETSS has
increased the tensile and thermal properties of eco-composites. The tensile strength and
modulus of elasticity of rPP/ETSS eco-composites with MA, PDMS and OSL were
higher than unmodified eco-composites. The degree of crystallinity and thermal stability
of modified eco-composites was also higher than unmodified eco-composites. The
better interfacial interaction between modified ETSS and rPP has been proven by
scanning electron microscope (SEM) studied. Spectra FTIR analysis has proven the
changes of functional group of modified ETSS. The modified eco-composites with MA
showed the highest tensile strength and thermal stability compared to the other modified
eco-composites. However, the modified eco-composites with PDMS indicated highest
modulus of elasticity and degree of crystallinity followed by modification with OSL and
MA eco-composites. |
