主要成就
研究方向为天然大分子修饰改性和功能化及环境友好材料的制备技术和应用开发研究。主持并完成部、委级科研项目12项，在科技成果转化为生产力方面作了大量的工作，并取得显著成绩。其中如以淀粉为原料经氧化成双醛淀粉再经表面微囊化覆醛和稳定化处理后，使其具有治疗氮质血症和尿毒症的尿素氮吸附药“包醛氧淀粉”获国家颁发的新药证书，被列为国家级新药，并获国家教委科技进步二等奖、国家科技进步三等奖。在此基础上引入固定化酶的技术研究开发的新一代产品“吸附尿素氮的胶囊口服剂”获国家发明专利授权。国家“八五”攻关项目“淀粉型光生物可控降解地膜的研究开发”在完成年产两千吨的规模化生产经天津市经委鉴定验收后，获国家计委批准进行万吨级的产业化实施工程。其核心技术堆肥环境自降解塑料的制备方法获发明专利授权。热塑性淀粉塑料是一类可完全降解的塑性材料。作为一种材料尚有许多基础问题要解决，如材料的机械性能、耐水性、淀粉的回晶等问题。近期在应用基础研究方面进行了探索性的研究，也取得一些初步成果。已公开发表研究论文100余篇，其中有40余篇 被SCI、EI收录。获授权发明专利二项。已培养出博士研究生6名、硕士研究生18名。目前有9名博士生、5名硕士生在学。
