摘　　要：以没食子酸、环氧大豆油和蓖麻油为原料,通过简单绿色的工艺制备了一系列可UV固化活性单体(GAM、SOM、COT),并将所制备的单体进行巯基-烯UV固化,制得一系列可再生碳含量较高的UV固化涂膜。通过核磁(~1H NMR)、热重分析仪(TGA)、差示扫描量热仪(DSC)、动态机械分析仪(DMA)对单体结构和膜的性能进行了表征分析,并研究了不同单体含量对涂膜机械性能、玻璃化转变温度(T_g)以及热性能的影响。结果表明:随着没食子酸基单体含量增加,UV固化涂膜的铅笔硬度和T_g有所提升,涂膜整体具有较好的热稳定性。A series of UV curable monomers （GAM, SOM and COT） were prepared by simple green process using gallic acid, epoxidized soybean oil and castor oil as raw materials. Those monomers were then used to prepare a series UV curing coating via thiol-ene UV curing process. The structure of the monomers and the properties of films were characterized by nuclear magnetic resonance （ NMR）, thermogravimetric analyzer （ TGA）, differential scanning calorimetry （DSC） and dynamic mechanical analyzer （DMA）. The effect of different monomer content on coating mechanical properties and thermal properties was studied. The results showed that the pencil hardness and glass transition temperature of the UV curing coating had been improved with the increase of the content of GAM, and all of the bio-based coating had good thermal stability.
