摘　　要：采用环氧氯丙烷法制备了新型生物基没食子环氧树脂、环氧基笼形倍半硅氧烷(E-POSS)、经甲基丙烯酸修饰的E-POSS(AE-POSS);利用浇注工艺制得新型杂化纳米生物基环氧树脂复合材料。考察了E-POSS,AE-POSS用量对新型杂化纳米环氧树脂复合材料的增韧效果、热稳定性、相容性的影响。结果表明:添加E-POSS,AE-POSS可提高复合材料的冲击强度及热稳定性;w(AE-POSS)为18%时,复合材料冲击强度较纯没食子环氧树脂提高了3.46 k J/m^2;w(E-POSS)为18%时,复合材料初始热降解温度较纯没食子环氧树脂提高了46.4℃。The novel bio-based gallic epoxy resin,polyhedral oligomeric silsesquioxane containing epoxy group(E-POSS),E-POSS modified by methyl acrylic(AE-POSS)were synthesized via chloropropylene oxide method.The novel bio-based hybrid nano epoxy resin was cured by casting process.The influence of E-POSS and AE-POSS content on toughening,thermal stability and compatibility of the nano epoxy resin were investigated.The results show that the impact strength and thermal stability of cured epoxy resin are enhanced by adding E-POSS or AE-POSS.The impact strength of the cured epoxy resin in which the mass fraction of AE-POSS is 18%is higher than that of pure gallic epoxy resin by 3.46 kJ/m2.The initial thermal degradation temperature of the cured epoxy resin is increased by 46.4℃than that of pure epoxy resin.
