本研究评价了含氟单体甲基丙烯酸2，2，2-三氟乙酯（TFEMA）对自聚合硬式直接义齿衬料树脂性能的影响。甲基丙烯酸异丁酯（i-BMA）和含有30重量%TFEMA的甲基丙烯酸2-羟乙酯（2-HEMA）用作单体，而聚（甲基丙烯酸乙酯）用作粉末。通过使用振荡流变仪、动态粘弹仪和接触角计测定凝固特性、动态机械性能和随时间的变化以及润湿性。还根据ISO规范测量吸水性和溶解度。基于i-BMA的衬里树脂具有更大的弹性和刚度性能，而基于2-HEMA的衬里树脂随着时间的推移显示出较少的动态力学性能变化。此外，吸水率和溶解度趋于降低，接触角增加。这项研究的结果表明，随着时间的推移，TFEMA提高了衬里树脂的机械性能和耐久性。
This study evaluated the effects of the fluorinated monomer of 2,2,2-trifluoroethyl methacrylate (TFEMA) on the properties of autopolymerized hard direct denture reline resins. Iso-butyl methacrylate (i-BMA) and 2-hydroxyethyl methacrylate (2-HEMA) containing 30% TFEMA by weight were used as monomers, while poly(ethyl methacrylate) was used as a powder. Setting characteristics, dynamic mechanical properties, and changes over time, as well as wettability were determined by use of an oscillating rheometer, dynamic viscoelastometer, and contact angle meter. Water absorption and solubility were also measured according to ISO specifications. The reline resin based on i-BMA had greater elasticity and stiffness properties, while that based on 2-HEMA showed fewer dynamic mechanical property changes over time with the addition of TFEMA. Furthermore, water absorption and solubility tended to be reduced and contact angle increased. The results of this study suggest that TFEMA improves mechanical properties and durability of reline resins over time.
