| Summary: | In this study, the physical, mechanical, and morphological properties of clay dispersed styrene-co-3-trimethoxy silyl propyl methacrylate
(ST-co-MSPM) impregnated wood polymer nanocomposite (WPNC) were investigated. The WPNC was characterized by Fourier
transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), 3-point bending and free-vibration testing. The FT-IR
results showed that the absorbance at 698 cm−1 was increased for ST-co-MSPM-clay-WPNC and ST-Clay-WPNC compared with other
composites and raw wood. Besides, the hydroxyl group (-OH) was significantly reduced as the strong covalent bond was formed
between the –OH groups of wood and the silyl propyl group of 3-trimethoxy silyl propyl methacrylate. The SEM results showed that
ST-co-MSPM -clay-WPNC had a smoother surface compared to other nanocomposites and raw wood. The introduction of clay in the
WPNC filled the void spaces of the wood and improved the intercalation between the wood and the polymer matrix. The modulus of
elasticity (MOE), modulus of rupture (MOR), and dynamic Young’s moduli (Ed) of WPNCs were considerably increased compare to
wood polymer composites (WPCs) and raw wood. The raw wood exhibited a higher water uptake (WU) than WPNCs and WPCs. |
