研究领域

1、以流变学和核磁共振为基础的多尺度表征技术高分子具有复杂的聚集态结构及独特的物理化学性能，对其结构与性能之间关系的研究是我们认识高分子本质的基础，对开发新型高分子材料及发展高分子物理理论具有重要意义。从合成高分子样品到高分子的加工成型，人们对高分子的理解和认识包含了从微观的化学键、链间弱相互作用及链段分子运动到宏观性能等多尺度的过程。为了获得对高分子在这些不同尺度下结构与性能的深入理解，各种实验表征技术已经被广泛地应用到高分子材料的研究中。而在众多表征手段中，核磁共振波谱学和流变学这两种独特技术的检测范围都有着显著的多尺度特征，并且两者对应的检测特征尺度互为补充，因此两者的有机结合将成为人们认识高分子本质和理解高分子结构设计到加工成型的新桥梁。本课题组尝试将多尺度的固体NMR检测技术和流变学技术有机的结合起来，在高分子物理理论指导下来理解高分子及其复合材料的结构和动力学，进而揭示高分子复杂聚集态结构的形成和演化机理及不同层次结构与宏观性能间的关系，为新型高分子材料的设计与制备提供理论依据，并从新材料研究所呈现的实验新现象中进一步发展高分子物理理论。 2、高性能高分子复合材料的合成及其独特性能的微观机理高性能高分子复合材料是当前高分子领域的研究热点之一，不论是超强超韧的材料，还是有特殊响应性的材料，在很多情况下，他们的独特性能都是多尺度上不同相互作用协同的结果。比如有机粘土和液体橡胶的复合物凝胶体系就包含着界面上的有机-无机相互作用（0.5-1nm）、靠近界面的强链段吸附作用（1-10 nm）、以及在更大一些的尺度上（>10 nm）的弱链段吸附作用。分别对应着空间尺度的还有从十几微秒到秒量级的时间尺度的不均匀性。我们试图通过这些时间与空间的多尺度性信息，揭示不同高分子复合物体系独特性能的根源。 3.受限态高分子非线性流变学行为的分子机理高分子流体在受限空间中的流变行为不同于本体，界面相互作用、受限维度、高分子拓扑结构等因素，都关系到高分子链的动力学行为，也直接影响到形变过程中高分子的链结构和缠结行为，以及最终高分子/受限界面的综合性能。通过制备不同缠结程度、具有不同拓扑结构和处于不同受限环境的高分子，借助非线性流变学、固体核磁共振（NMR）、无辐射能量转移荧光光谱、介电、力学谱、电镜等方法研究高分子链在受限空间中的运动、分布的规律，阐明受限态高分子非线性流变行为的分子机理。进而运用这些受限态下的微观规律，制备得到强韧的有机/无机复合材料界面。对受限态高分子非线性流变学行为的这些理解，为5G通讯PCB板为代表的先进制造领域提供高性能界面提供了新的解决思路。
