A novel benzoxazine monomer, using polydatin as phenol source and furfurylamine as amine source (PDA-fa) was successfully synthesized. 1H nuclear magnetic resonance spectroscopy (1H NMR) and Fourier transform infrared spectroscopy (FT-IR) were carried out to confirm the structure of PDA-fa. The curing behaviors were investigated by differential scanning calorimetry (DSC) and in situ FT-I. PDA-fa exhibits an endothermic peak at 183 ℃. The C=C bond and furan structure can be crosslinked during the ring-opening polymerization of oxazine ring. Additionally, the thermal property of poly(PDA-fa) and the surface property of benzoxazine membrane were further investigated. The glass transfer temperature of poly(PDA-fa) is 230℃(DSC) and 231 ℃(TMA). The value of Td5 and Td10 are 306 and 338 ℃, respectively, and a char yield at 800 ℃ is as high as 61%. The surface free energy of the completely cured benzoxazine membrane is calculated to be 43.6 mJ/m2.
