摘要: 为改善聚酯的血液相容性,以聚酯织物为基材,通过等离子体技术和化学接枝相结合在其表面接枝丙烯酸。探讨丙烯酸单体浓度、助剂浓度、反应温度等因素对改善聚酯织物血液相容性的影响,并确定了优化实验条件。实验结果表明:将聚酯织物置于功率为100 W、真空度为50 Pa的Ar气氛等离子体作用3 min后,采用质量分数为0.4%的联苯、质量分数为0.3%的亚甲基二萘磺酸钠在反应温度为85℃条件下,以过氧化苯甲酰为引发剂接枝丙烯酸于等离子体处理过的聚酯织物,改性后的聚酯织物具有较好的接枝效果和血液相容性。

Abstract: Acrylic acid was grafted onto the surface of polyester textiles by exposing the textiles to the plasma,followed by the chemical reaction.The influencing factors such as the concentration of the acrylic acid and auxiliary as well as reaction temperature on the blood compatibility was studied and the optimized treatment conditions were suggested.Firstly,the polyester textile was treated by plasma in which the vacuum degree was(50 Pa),the power was(100 W,) and argon was used for(3 min.) Then,acrylic acid was grafted onto the surface of plasma treated polyester textiles by chemical reaction in which the concentration of DP was(0.4%,) NNO was(0.3%,) reaction temperature was(85 ℃) and initiator was benzoyl peroxide(BPO).The results showed that the blood compatibility of the polyester textiles thus treated was good.
