In this study, physico-mechanical, thermal, and morphological properties of wood polymer nanocomposites (WPNCs) of styrene-co-ethylene glycol dimethacrylate with clay (ST-co-EGDMA-clay) and styrene with clay (ST-clay) wood polymer composite (WPC) of styrene-co-ethylene glycol dimethacrylate (ST-co-EGDMA) and styrene (ST) were investigated. The WPNC was characterized by Fourier Transform Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), 3-point bending and free-free vibration testing, and thermogravimatric analysis (TGA). The FT-IR results showed that the absorbance at 1730 cm−1 increased for ST-co-EGDMA-clay-WPNC and ST-co-EGDMA-WPC compared to other composites and the raw wood. The XRD result revealed that the d-spacing of ST-clay-WPNC, ST-co-EGDMA-WPC, ST-WPC, and ST-co-EGDMA-clay-WPNC was higher than the raw wood. The SEM results showed that ST-co-EGDMA-clay-WPNC and ST-clay-WPNC had a smoother surface compared to the other composites and raw wood. The modulus of elasticity (MOE), modulus of rupture (MOR), and dynamic Young’s moduli (E d) of ST-co-EGDMA-clay-WPNC were higher than those of ST-co-EGDMA-WPC, ST-clay-WPNC, ST-WPCs, and raw wood, respectively. The raw wood exhibited a higher water uptake (WU) compared to WPNCs and WPCs. ST-co-EGDMA-WPC was more thermally stable, compared to other composites and raw wood.
