研究成果

方向一、新型水凝胶材料的设计合成及在水环境净化方面的应用
水凝胶凭借亲水的三维网络特征、可控调节的网络形貌和可剪裁的功能基团,对水体中的氮磷、重金属、染料、稀土、放射性物质以及盐湖资源中的高值稀散元素铷铯锶等均具有良好的去除、分离和富集效果,因而成为具有潜在应用开发价值的一类新型水环境净化材料。
i) 从工艺上通过水溶液分散聚合实现了一步法使水凝胶材料的制备从常规胶体状到粒状产品的突破。在此过程中,解决了材料的均匀性和成粒性等关键科学问题。ii) 从技术上利用Fenton试剂解决了水凝胶材料的制备从高温惰性气氛向室温空气氛的转化。创新性地实现了室温和空气氛条件下粒状水凝胶材料的完美制备,为水凝胶材料的大规模生产及应用提供了一条绿色的、经济的通道。iii) 从结构上介入具有不同精细结构和维数的无机黏土,揭示了不同类型无机黏土对水凝胶的增强机理。研究了微观上呈层状、层链状、管状等不同精细结构的无机黏土对水凝胶材料所构筑的微观结构以及宏观性能的影响,为延伸无机黏土产业链及实现无机黏土资源的高值化开辟了新的途径。iv) 从功能上,以水凝胶的三维网络作为尺寸限域的微纳反应器,成功获得金属纳米粒子封装的异相催化材料。将水凝胶尺寸限域的微纳反应器特征与金属纳米粒子的表面效应结合,为水凝胶材料在环境催化领域的应用提供了数据支撑和可能的应用拓展。v) 从应用上通过分子设计提高了水凝胶材料对不同污染物的选择性吸附,为稀贵金属的富集回收提供了有益借鉴。从分子设计出发,在形态上,先后发展了胶体状、粒状以及柱状多孔水凝胶材料;在组成上,先后发展了有机聚合物水凝胶、有机-无机复合水凝胶、生物可降解水凝胶。
方向二、天然植物纤维的功能化改性及在污染物治理方面的应用
天然植物纤维是自然界中储量丰富的可再生生物质资源,具有良好的生物相容性和可降解性。从利用材料的本体结构性能出发和微纳结构设计入手,对木棉纤维和牛角瓜纤维进行了深入而系统的科学研究,并形成新颖而独特的研究视角。
i) 利用木棉纤维结构导向的生物模板作用,得到新型的水环境净化材料。构筑了具有吸附和催化双功能的水环境净化材料,对水体中的特定有机污染物表现出良好的催化转化能力。ii) 结合木棉纤维的中空形态结构和优良的疏水亲油性能,拓展进行了木棉纤维作为新型吸油材料方面的研究工作。实现了对木棉纤维表面的可控设计与调控,为研发高油水分离性能的新型可生物降解吸油材料奠定了实验和理论基础。iii) 从利用牛角瓜纤维的本体结构性能出发,报道了牛角瓜纤维作为新型可生物降解吸油材料的可行性。揭示了纤维的本体结构与高效吸油性能之间的关系,为设计和开发其他类型的吸油材料提供了借鉴。
方向三、多功能保水节水材料的研制及在生态修复中的应用
作为一种新型的水环境净化材料,水凝胶不仅可对水环境中的污染物具有高效富集效果,还可通过其组成调控得到新型的多功能保水节水材料。通过材料与技术集成,多功能保水节水材料在生态修复方面展现出不可估量的应用潜力。

i) 引入具有良好化学活性和生物活性的腐植酸,开展了具有缓释肥料功能多功能保水节水材料的研究工作。在科技部863项目的联合资助下,先后开展了单纯有机聚合物、有机-无机复合以及新一代可生物降解的多功能保水节水材料的研制工作。ii) 多功能保水节水材料在生态修复中的应用示范。多功能保水节水材料经放大生产后,试用于甘肃周边地区马铃薯等农作物种植,取得了良好的社会和经济效益。
