| Summary, etc. |
The depletion of fossil fuels and the increasing demand for sustainable materials have driven research into renewable alternatives, leading to the development of biopolyurethane foams from methacrylated lignin and acrylated epoxidized palm oil (AEPO). Synthesized with isophorone diisocyanate (IPDI) and characterized through Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and mechanical testing, the results indicated that incorporating methacrylated lignin improved mechanical strength and thermal stability, while AEPO enhanced crosslinking, rigidity, and high-temperature stability. Optimal AEPO-lignin ratios yielded foams with superior stiffness, structural integrity, and thermal resistance; however, excessive lignin reduced density, increased brittleness, and limited water absorption due to decreased porosity. Water uptake analysis demonstrated a balance between hydrophilicity and crosslinking, with some compositions exceeding 280% saturation, while mechanical testing revealed that balanced formulations provided better load-bearing capacities compared to those with high lignin content, which compromised performance. Overall, the study highlights the potential of lignin and AEPO-based polyurethane foams as promising sustainable alternatives with tailored properties for various industrial applications. |
