SUMMARY OF MY RELEVANT RESEARCH AREAS:
Polymer Nanocomposites; Bioelastomer; Polymer Processing; Rubber Science and Technology
聚合物纳米复合材料;生物弹性体;聚合物加工;橡胶材料科学与工程
Primary Research interests:
1. With the goal of developing the biomaterials applications such as drug delivery matrix
materials, tissue engineering scaffolds materials and organ-repairing materials, the
research focuses on preparation of novel polymer materials with high elasticity and
various biofunctionality. Main research fields are molecular design, synthesis method,
structure and property of novel bioelastomer materials, nano-reinforcement and
nano-modification of bioelastomer materials, the preparation methods of
biodegradable porous scaffolds. Attention is also paid to the time-dependent and
environment-dependent properties of the structure and biofunctionality on the
bioelastomers as well as cooperation with the hospital on animal experiments and
clinical application of bioelastomer materials, etc.
2. Based on the requirement of nation development strategy, such as resource,
environment, energy, and so on, we study on the recycling science & technology of
the cross-linked rubber, preparation science & technology of energy-saving/
environment friendly/recyclable thermoplastic elastomer, preparation science &
technology of advanced material aiming at oil-saving tire. Among these, we emphasize on: science of rubber
dynamic vulcanization, science of the crosslink and de-crosslink of rubber, and science of the viscoelasticity and
hysteresis of rubber at broad vibration frequency range, and effect of interface on poly-phase, multi-component
rubber compounds, and so on.
3. Study on filled elastomer matrix with both high-elastic performance and specific
functions such as sound property, luminescence property, electrical conductivity,
magnetic property. Focus on the design and development of filler structure and
interface structure, the relationship of filler structure and functional response, the
relationship of functions and stress, strain, temperature, and other outside fields, and its
evolution with time. Develop functional elastomer composites with low-cost and high-performance, develop
relevant whole set of product processing technology.
4. Focus on describing and characterizing multi-level and multi-scale structures of nano-dispersion reinforced
rubber composites, developing methods of forming random or ordered nano-dispersed structures in rubber
matrix, investigating thermodynamics and kinetics of nano dispersion and aggregation using statistical
mechanics and molecular simulation methods, mechanism of nano-reinforcement (e.g. modulus, stress, strain,
strength), relationship between the complex structure and performance of the nanocomposites, developing
industrial low-cost and high- performance nano reinforcement technology and nano-composites.
