摘　　要：以EVA-150和淀粉为原料,采用螺杆机挤出工艺,制备一种可生物降解的EVA-150/淀粉复合基材,用作除草剂咪草烟的控制释放。通过SEM、DSC和UV分析测试,研究了EVA-150/淀粉共混物的相容性、结晶度及其对咪草烟的释放性能。实验结果表明:EVA-150/淀粉基材具有明显的控制释放作用,在pH=4、7、9环境中,9d以后咪草烟的释放量都大于50%。The EVA-150 and starch were extruded by extruser and the bio-degradation composite material was prepared that used as the controlled-release matrix of imazethapyr. The compatibility and crystalhnity of EVA-150/starch blending were analyzed by SEM and DSC,and the controlled-released performance of imazethapyr in the matrix materials was also investigated by UV analysis. It was shown that EVA-150/ starch composite matrix has the obvious controlled-released function and the release rates of imazethapyr all exceed 50% in the environment of pH 4, pH 7,or pH 9 after 9 days.
