摘要：使用虎杖苷作为酚源，糠胺作为胺源合成了全生物基苯并嗪单体（PDA-fa），采用 HNMR 和 FTIR 表
征了单体的结构。以 DSC 和原位红外（In situ FTIR）研究了 PDA-fa 的固化行为，采用热机械分析（TMA）仪、
TG 和接触角测量仪测试了虎杖苷-糠胺基聚苯并嗪〔Poly(PDA-fa)〕膜的热性能及表面性能。结果表明，PDA-fa
的固化峰值温度为 183.4 ℃。Poly(PDA-fa)的玻璃化转变温度达到 230 ℃（DSC）/231 ℃（TMA），5%和 10%热
2
失重温度分别为 306 和 338 ℃，800 ℃残炭率高达 61%。其膜的表面能为 43.6 mJ/m 。PDA-fa 具有一定水溶性，
其热聚合为经典的嗪环阳离子开环聚合，呋喃结构和连接单元中双键也可产生额外交联作用，有助于形成三
维网络结构，并具备形成涂层膜的能力。随着固化程度提高，Poly(PDA-fa)膜表面更亲水。

Abstract: A fully bio-based benzoxazine monomer (PDA-fa) was synthesized by using polydatin as phenol
1
source and furfurylamine as amine source and characterized by HNMR and FTIR. The curing behaviors of
PDA-fa were investigated by DSC and in situ FTIR. Thermal and surface properties of polydatin-
furfurylamine based polybenzoxazine [Poly(PDA-fa)] films were measured by thermomechanical analysis
(TMA), TGA and contact angle meter. The results showed that PDA-fa exhibited an endothermic peak at
183.4 ℃. The glass transfer temperature of Poly(PDA-fa) was 230 ℃ (DSC)/231 ℃ (TMA). The 5% and
10% mass loss temperatures were 306 and 338 ℃, respectively. The char yield at 800 ℃ was as high as
2
61%. The surface energy of film was 43.6 mJ/m . PDA-fa had a certain water solubility, and its thermal
polymerization is the classical cationic ring-opening polymerization of oxazine ring. The furan structure and
the double bond in the connecting unit could produce extra crosslinks, which contributed to the formation of
three-dimensional network and had the ability to form a coating film. With the improvement of curing
degree, the surface of Poly(PDA-fa) film became more hydrophilic.
