烯酸羟乙酯以不同质量比热固化构筑体系材料。利用 FTIR、 HNMR 对 PPF 进行了表征,通过 TG-DSC、全自
动视频接触角测试仪、拉伸试验机测试了体系材料的热稳定性、润湿性能、力学强度,评价了体系材料的体外
细胞毒性及降解性能。结果表明,体系材料具有较好的热稳定性、亲水性及力学强度,其水接触角为
(53.28°±2.36°)~(76.17°±0.81°),拉伸剪 切 强度、拉 伸 粘接强度 、 最大抗压 强 度、三点 弯 曲强度分 别为
(1.33±0.08)~(1.63±0.54) MPa 、 (1.86±0.07)~(3.18±0.29) MPa 、 (60.47±3.47)~(88.15±7.09) MPa 、
(18.77±1.12)~(20.63±1.48) MPa。体外降解实验结果表明,随着浸泡时间的延长,体系溶液 pH 呈下降趋势,pH
变化值为 0.093~0.628。当 PPF 和丙烯酸羟乙酯质量比为 3∶1 时,试样 3 的失重率和吸水率最高,分别可达 11.20%
和 38.27%,降解速率较为缓慢。此外,体系材料对 MC3T3-E1 小鼠颅顶前骨细胞的毒性轻微。

Abstract: Poly(propylene fumarate) (PPF) was successfully synthesized from diethyl fumarate and
1
1,2-propanediol via two-step reaction and characterized by FTIR and HNMR. And then a series of
thermally cured system materials were obtained by mixing PPF and hydroxyethyl acrylate in different mass
ratios. The thermal stability, wetting properties and mechanical strength of system materials were measured
by TG-DSC, automatic video contact angle and tensile machine, followed by in vitro cytotoxicity and
degradation evaluation. The results showed that the system materials exhibited good thermal stability,
hydrophilicity with water contact angles ranging from (53.28°±2.36°) to (76.17°±0.81°), and mechanical
strength, with tensile shear strength, tensile bonding strength, maximum compressive strength and
three-point bending strength of (1.33±0.08)~(1.63±0.54) MPa, (1.86±0.07)~(3.18±0.29) MPa,
(60.47±3.47)~(88.15±7.09) MPa and (18.77±1.12)~(20.63±1.48) MPa, respectively. In vitro degradation
analysis indicated the system pH displayed a decrease trend with soaking time. The pH variation value was
0.093~0.628. Meanwhile, system material with a mass ratio of PPF to hydroxyethyl acrylate of 3∶1
showed maximum mass loss rate and water absorption rate, which were 11.20% and 38.27%, respectively,
indicating a relatively slow degradation rate. Moreover, in vitro cytotoxicity analysis on murine cell line
