Abstract
The present study showed the potential of PVA (polyvinyl alcohol)/starch reinforced with date palm leaf (DPL) fiber-based hybrid composite for packaging applications. The surface modification of date palm fiber is carried out with Potassium hydroxide (KOH). The effect of the chemical treatment is examined by Scanning electron microscopy (SEM) and tensile test. KOH treated date palm leaf (DPL) fiber proves to be the best reinforcement material for composite and increases the compatibility between fiber and matrix. A completely new hybrid composite is prepared by taking Corn starch along with PVA reinforced with KOH treated DPL fiber. The effect of different fiber content was studied from tensile, flexural, and impact properties of the composite. The composite with 30 wt% of fiber exhibits better results. The thermal behavior of the composite was studied using thermogravimetric analysis (TGA). Composite proved to be more thermal stable than a neat PVA. The water absorptivity and bio-degradation properties of the composite are evaluated. The incorporation of DPL fiber into the composite reduced the biodegradation rate of the hybrid composite.
