| Summary: | Pineapple leaf is a residue mainly from pineapple food industry which is causing
environmental problems by its lack of proper waste disposal method. Therefore, it
can be utilized as filler for the reinforcement of PLA which is brittle in nature. Treated
fiber from pineapple leaf fiber (PALF) was derived through acid hydrolysis method.
The morphological properties and chemical structure of treated PALF were
determined using scanning electron microscopy (SEM) and Fourier-transform infrared
spectroscopy (FTIR). Plasticized PLA/treated PALF was prepared by solvent casting
method at 1wt%, 3wt%, 5wt% and 7wt% loading rates of acid hydrolysis treated
PALF. Mechanical properties of composite were characterized through tensile test.
FTIR analysis shows significant changes in the chemical properties of the raw PALF
and treated PALF. SEM image reveals that acid hydrolysis treated PALF displays a rod
like structure and smooth surface as the effect of hemicellulose removal. The findings
of this research is expected to decrease the amount of waste accumulated in the
environment due to non-degradable materials and the pineapple industry residues. |
