Dissertation note: Final Year Report (Bachelor Degree of Applied Science on Material Technology) -- Universiti Malaysia Pahang Al-Sultan Abdullah - 2025 Abstract: Benzoxazine resins have gained attention in materials research due to their impressive mechanical strength, chemical resistance, flame retardancy, and thermal stability. This research addresses environmental concerns associated with petroleum-based products by synthesising bio-based benzoxazine monomers using renewable resources, such as coumaric acid, ferulic acid, and 2-(4-hydroxyphenyl) acetic acid, chosen for their distinct structural characteristics. The synthesis process employed a solvent-based method, and the monomers' chemical structures were confirmed using Fouriertransform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopy. Thermal stability and curing behaviour of the resultant polybenzoxazine materials were evaluated using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Results demonstrated that bio-based polybenzoxazines exhibited improved dimensional stability and thermal properties, with FEA-Bz showing the lowest polymerisation temperature due to the presence of methoxy groups. This study promotes sustainable material development, advancing applications in electronics, aerospace, and biomedical engineering

Benzoxazine resins have gained attention in materials research due to their impressive mechanical strength, chemical resistance, flame retardancy, and thermal stability. This research addresses environmental concerns associated with petroleum-based products by synthesising bio-based benzoxazine monomers using renewable resources, such as coumaric acid, ferulic acid, and 2-(4-hydroxyphenyl) acetic acid, chosen for their distinct structural characteristics. The synthesis process employed a solvent-based method, and the monomers' chemical structures were confirmed using Fouriertransform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopy. Thermal stability and curing behaviour of the resultant polybenzoxazine materials were evaluated using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Results demonstrated that bio-based polybenzoxazines exhibited improved dimensional stability and thermal properties, with FEA-Bz showing the lowest polymerisation temperature due to the presence of methoxy groups.
