The present work focuses on investigating the effect of short chain alkylsilane treatment on the surface characteristic of date palm (Phoenix dactylifera) fiber. Raw date palm fiber was treated with octylsilane and surface properties of treated fiber was investigated using thermogravimetric analysis (TGA), fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), contact angle analysis and X-ray diffraction (XRD) on configuring the thermal stability, chemical structures and surface properties (morphology, hydrophobicity and crystallinity). Thermal properties, hydrophobicity and crystallinity increased with introducing octylsilane compared to raw date palm fiber. The SEM and XRD experimental results showed that the alkylsilane treatment can effectively remove non-crystalline cellulosic materials. Thermal stability, hydrophobicity and crystallinity of the fibers were found to increase on alkylsilane-treatment. The results indicated that alkylsilane-treated DPFs were a suitable reinforcing substitute for hydrophobic polymer composite. |
