| 总结: | In this research, pineapple leaf fiber (PALF) reinforced polyester composites
were developed and enhanced with nanofiller bamboo particles. Characterization of
bamboo nanofiller such as surface morphologies, elemental composition and
functional groups were evaluated by using Scanning Electron Microscopy equipped
with Energy Dispersive X-ray Analysis (SEM with EDX) and Fourier Transform
Infrared Spectroscopy (FT-IR) respectively. The SEM-EDX images revealed that
bamboo nanofiller produced consisted of crushed and irregular shape structures with
presence of carbon and oxygen as a major elements composition. Besides,
Transmission Electron Microscope (TEM), X-ray Diffraction (XRD) and
Thermogravimetric Analysis (TGA) were used to characterize particle size,
crystallinity index and thermal properties of bamboo nanofiller respectively. The
TEM micrograph revealed that bamboo particles size ranged between 10 to 30 nm
indicates their nanometric nature. Percentage crystallinity of bamboo nanofiller by
XRD analysis comes out to be 42.90%, show its lower degree of crystallinity index.
Effect of different filler loading (O, l, 3, and 5 wt %) of bamboo nanofiller into
pineapple leaf fiber (PALF) reinforced polyester composites were studied. The
physical, mechanical, morphological and thermal properties of the composites were
studied. It was observed that with incorporation of bamboo nanofiller into the
composites increased its physical properties such as the density, void content and
water absorption as filler loading increases.
