双层结构纳米羟基磷灰石/硅橡胶复合材料的制备及性能

Preparation and characterization of nano-hydroxyapatite/silicone rubber composite with double layers

纳米羟基磷灰石/硅橡胶与硅橡胶在同时硫化的条件下制备出了双层结构的纳米羟基磷灰石/硅橡胶复合材料,利用XRD、SEM、MTT和力学性能测试等手段对复合材料进行表征。结果表明,两层材料的界面结合紧密,材料的细胞相容性好,力学性能与硅橡胶的力学性能相近,能够达到医用植入硅橡胶材料的要求。

Nano-hydroxyapatite/silicone rubber with double layers was prepared by curing both mixtures of nanohydroxyapatite/silicone rubber and silicone rubber simultaneously. XRD,SEM,MTT and mechanical tests were employed to characterize the composite. The results indicate that the composite has a combining close interface, good cell compatibility and mechanical properties similar to silicone rubber. It can meet the requirement of silicone rubber as a medical implant material.
