dc.description.abstract |
Polypropylene - micro crystalline cellulose-based composites have shown great potential in
various applications as a modern composite material. Microcrystalline cellulose has gained great
interest in composite fabrication as a reinforcing material, with the advantages of higher physical
and mechanical properties, which comes with its peculiar micrometric dimensions. In this study,
microcrystalline cellulose was incorporated into polypropylene based composites to improve the
electrical properties of Polypropylene based polymer composites.
Hydrophilic Microcrystalline cellulose creates a weak interface with hydrophobic polypropylene
resulting poor compatibility in two materials. Therefore, sunflower oil ethyl esters were used as
the surface modifier to improve the compatibility with hydrophobic polypropylene. Sunflower oil
ethyl esters were trans esterified onto microcrystalline cellulose surface using ultrasonication
technology to enhance the surface hydrophobicity of microcrystalline cellulose. Modified
microcrystalline cellulose was characterized by FTIR, SEM and wettability analysis. The electrical
properties such as dielectric loss, dielectric constant and AC electrical conductivity of the
developed composites were experimentally determined in this study. Experimental results
indicated that the variation of dielectric constant and dielectric loss characteristics values of
Polypropylene-microcrystalline cellulose composites at different microcrystalline cellulose
loadings over the frequency range of 50 Hz – 5MHz. |
