Degradable Mg-Ca/Mg-Cu composite barrier membrane and preparation method and application thereof

The invention discloses a degradable Mg-Ca/Mg-Cu composite barrier film, and particularly relates to an Mg-Ca/Mg-Cu composite barrier film and a preparation method thereof, and the Mg-Ca/Mg-Cu composite barrier film comprises the following components in percentage by weight: 0.3 to 1.0 percent of Mg-Ca alloy of Ca, 0.1 to 0.5 percent of Mg-Cu alloy of Cu, and the balance of Mg and inevitable impurities. The preparation method comprises the steps that the surfaces of the two plates are polished through abrasive paper, the two plates are put under a roller to be subjected to ply rolling, and finally the Mg-Ca/Mg-Cu composite barrier film is prepared. The barrier film has good antibacterial performance on the gingival side and good osteogenesis promoting performance on the alveolar bone side. 本发明公开了一种可降解Mg-Ca/Mg-Cu复合屏障膜，具体涉及一种Mg-Ca/Mg-Cu复合屏障膜及其制备方法，所述Mg-Ca/Mg-Cu复合屏障膜按重量百分比计算包括如下组分：0.3~1.0%的Ca的Mg-Ca合金，0.1~0.5%的Cu的Mg-Cu合金，余量为Mg和不可避免的杂质。制备方法为：将两种板材的表面用砂纸打磨光亮，放在轧辊下叠轧，最终制得Mg-Ca/Mg-Cu复合屏障膜。满足屏障膜在牙龈侧具备良好的抗菌性能，牙槽骨侧具有良好的
