Elucidation of mechanism of nonlinear viscoelasticity in polymer condensed systemIn polymer condensed system, intermolecular entanglements are formed due to topological interaction. Nonlinear viscoelasticity in polymer condensed system has been found to be due to disentanglement in chain equilibration process and irreversible change in entanglement network.2.Elucidation of mechanism of nonlinear viscoelasticity in nanofiller/organic compositesWe have found that nonlinear viscoelasticity in nanofiller/organic composites is based on rupture and recovery in nanofiller network from the concurrent measurements of stress relaxation and electric conductivity.3.Evaluation of modulus of bound rubber in nanofiller/organic compositesWe have developed a novel method for evaluation of modulus of bound rubber in nanofiller/organic composites using acoustic techniques, scanning acoustic microscopy and longitudinal wave velocitometry.

聚合物凝聚体系中非线性粘弹性机理的阐释在聚合物凝聚体系中，分子间的缠结是由拓扑相互作用形成的。聚合物凝聚体系的非线性粘弹性是由于链平衡过程中的解缠结和缠结网络的不可逆变化造成的。纳米填料/有机复合材料的非线性粘弹性机理研究通过对纳米填料网络的应力松弛和电导率的同时测量发现，纳米填料/有机复合材料的非线性粘弹性是建立在纳米填料网络破裂和恢复的基础上的。纳米填料/有机复合材料中粘结橡胶模量的评价我们开发了一种利用声学技术、扫描声学显微镜和纵波测速法来评价纳米填料/有机复合材料中粘结橡胶模量的新方法。
