摘　　要：研究了影响生物可降解多功能医用膜气雾剂的成膜的因素以及所得膜的性能以及气雾膜的止血效果。分别制得不同的气雾剂,观察包括成膜时间、膜均一性、膜粒径大小及膜厚度等成膜性。以材料:丙酮:氟利昂=0.5g∶0.5g∶4g制备的气雾剂成膜快,膜均一好。使用拉伸法测定所得膜的杨氏模量与断裂伸长率,所得膜的杨氏模量约为0.0373 GPa,断裂伸长率为0.89%。结果显示生物可降解多功能医用膜气雾剂成膜性良好,止血效果极好。The aerosol of biodegradable multi-function film were prepared, whose properties, affective factors and hemostasis effect were studied. Film formation properties were investigated in different lots of aerosols, including film formation time, uniformity, film particle size and film thickness. Young＇s modulus was about 0. 0373GPa, and elongation at break was 0. 89% by means of tensile method. It is proved that the aerosol of biodegradable multi-function film is easy to form films and its hemostasis effect is well.
