Pages: 49-53
Year: Issue:  1
Journal: Journal of Southwest University for Nationalities(Natrual Science Edition)

Keyword:  水性聚氨酯羟基磷灰石复合材料;
Abstract: 以聚乙二醇、聚己内酯二元醇为软缎,赖氨酸为扩链剂,和异佛尔酮二异氰酸酯采用丙酮法合成了固含量为10%的水性聚氨酯(WPU)乳液.并采用物理共混法,与纳米羟基磷灰石(nHA)物理混合,制备了WPU/nHA复合材料.通过X射线衍射(XRD),拉伸测试,接触角和吸水率测试,对复合材料薄膜的结构和性能做了表征和讨论.
