人物成就
生物高分子材料是李速明教授的研究领域。他通过对PLA、PGA、PCL及其共聚物等脂肪族聚酯的生物降解进行全面而系统的研究，发现了“内部自催化降解”这一新的降解机理，即聚酯材料在降解过程中，由于材料内部存在自催化现象，内部降解速度比表面更快。
他所发现的降解机理揭示了聚合物组成和构象结构、聚集态结构、分子量、尺寸、添加剂等一系列参数对聚合物材料降解行为的影响，以及这些参数在降解过程中的变化。这一发现对人类的健康极其有利。“内部自催化降解机理”及相关研究成果发表在一系列论文中，在国际学术界产生了广泛影响，被广泛引用。在1990年，这一发现被《人民日报》（海外版）称之为生物降解性高分子领域的“经典性论文”。
此外，他通过对PLA/PEG共聚物进一步深入研究，发明了新一代水凝胶，这种新型的产品可以有效的避免使用有机溶剂。这种水凝胶不仅具有优良的生物相容性、生物降解性、生物吸收性、可注射性，还具有热敏性，即水凝胶的性能随温度和时间变化，可以在体温下成胶。同时还具有合成简单，制备方便的优点。所以它们既是药物控释的理想载体，也可用作组织工程的骨架材料。
他通过参与科技部973计划“导向性纳米载药系统及其在脑部疾病治疗与诊断中的应用基础研究”，深入研究了PLA-PEG嵌段共聚物纳米胶束的制备、基本性质，以及胶束在药物控释领域的应用。提出了直接溶解法这一新型的纳米胶束制备方法，该方法避免了有毒的有机溶剂的使用，操作简单，在药物控释研究领域具有很好的发展前景；采用等摩尔的PLLA-PEG和PDLA-PEG制备得到了L/D混合型胶束溶液，利用PLLA和PDLA链段间较强的立体复合作用使得所得胶束结构更加致密；三是通过改变共聚物组成等方式控制胶束的包药能力及释药特性，实现了可控的药物缓释。PLA-PEG纳米胶束在药物控释领域，特别是疏水性抗癌药控释方面具有广阔的应用前景。
此外，他还对聚合物的酶降解进行了深入研究，初步揭示了酶降解机理，明确了聚合物结晶度、立体化学结构、共混等一系列参数对材料酶降解的影响。
