一种可降解脂肪族聚碳酸酯薄膜及其制备方法
摘要：
本发明公开了一种可降解脂肪族聚碳酸酯薄膜及其制备方法。所述薄膜的孔径为3～20μm，开孔率为5%～80%，厚度为1～100μm。本发明所提供的薄膜的制备方法，包括如下步骤：将所述脂肪族聚碳酸酯溶于溶剂中得到铸膜液；将所述铸膜液倾倒于铸膜板上并进行铺展，然后依次经静置和干燥至恒重的步骤即得产品。本发明所提供的上述可降解脂肪族聚碳酸酯薄膜具有多孔性的特性，在生物、医药、化工、环境等领域有着广泛的应用前景；本发明所提供的多孔可降解脂肪族聚碳酸酯薄膜的制备方法工艺简单，操作简便、容易实现、对设备依赖性低且用料少。
摘要（英）：

The invention discloses a degradable aliphatic polycarbonate film and a preparation method thereof. The film has a bore diameter of 3 mu m-20 mu m, an aperture ratio of 5%-80% and a thickness of 1 mu m-100 mu m. The preparation method of the film comprises the following steps of dissolving aliphatic polycarbonate in a solvent to obtain film casting liquor; and pouring the film casting liquor on a film casting plate and spreading, and stewing and drying to constant weight in sequence to obtain a product. The degradable aliphatic polycarbonate film provided by the invention has porosity characteristic and wide application prospect in the fields of biology, medicine, chemicals, environment and the like. The preparation method of the degradable aliphatic polycarbonate film is simple in process, simple and convenient to operate, easy to realize, low in device dependency and fewer in materials.
