成就

生物高分子材料是李速明教授的研究領域。他通過對PLA、PGA、PCL及其共聚物等脂肪族聚酯的生物降解進行全面而系統的研究,發現了“內部自催化降解”這一新的降解機理,即聚酯材料在降解過程中,由於材料內部存在自催化現象,內部降解速度比表面更快。
他所發現的降解機理揭示了聚合物組成和構象結構、聚集態結構、分子量、尺寸、添加劑等一系列參數對聚合物材料降解行為的影響,以及這些參數在降解過程中的變化。這一發現對人類的健康極其有利。“內部自催化降解機理”及相關研究成果發表在一系列論文中,在國際學術界產生了廣泛影響,被廣泛引用。在1990年,這一發現被《人民日報》(海外版)稱之為生物降解性高分子領域的“經典性論文”。
此外,他通過對PLA/PEG共聚物進一步深入研究,發明了新一代水凝膠,這種新型的產品可以有效的避免使用有機溶劑。這種水凝膠不僅具有優良的生物相容性、生物降解性、生物吸收性、可注射性,還具有熱敏性,即水凝膠的性能隨溫度和時間變化,可以在體溫下成膠。同時還具有合成簡單,製備方便的優點。所以它們既是藥物控釋的理想載體,也可用作組織工程的骨架材料。
他通過參與科技部973計畫“導向性納米載藥系統及其在腦部疾病治療與診斷中的套用基礎研究”,深入研究了PLA-PEG嵌段共聚物納米膠束的製備、基本性質,以及膠束在藥物控釋領域的套用。提出了直接溶解法這一新型的納米膠束製備方法,該方法避免了有毒的有機溶劑的使用,操作簡單,在藥物控釋研究領域具有很好的發展前景;採用等摩爾的PLLA-PEG和PDLA-PEG製備得到了L/D混合型膠束溶液,利用PLLA和PDLA鏈段間較強的立體複合作用使得所得膠束結構更加緻密;三是通過改變共聚物組成等方式控制膠束的包藥能力及釋藥特性,實現了可控的藥物緩釋。PLA-PEG納米膠束在藥物控釋領域,特別是疏水性抗癌藥控釋方面具有廣闊的套用前景。
此外,他還對聚合物的酶降解進行了深入研究,初步揭示了酶降解機理,明確了聚合物結晶度、立體化學結構、共混等一系列參數對材料酶降解的影響。
