Current Research Interests

 

Our group focuses on both organic and inorganic materials, as well as functional organic and inorganic hybrids based on the unique assembly of multiple components. In most cases, the design and control of the structure are the keys to the high performance of these materials.

 

  • Multi-functional nanostructured materials via self-assembly/nano-macro fabrication/3D printing for structural, functional, environmental and energy related applications

Nanocoatings containing a high concentration of well-aligned inorganic nanosheets for barrier, mechanical, and dielectric applications. (Ding, et al. Science Advances 20173, e1701212)

 

Multi-layered stimuli-responsive dynamic wrinkling system for anti-counterfeiting, encryption, and light diffusing applications. (Zeng, et al. Advanced Materials 201729, 1700828)

 

Cobalt ferrite/polyaniline nanocomposites with a large negative giant magnetoresistance at room temperature. (Gu, et al. Polymer 2018, 43, 324)

 

  • Functional inorganic solids via solid state chemistry/physics for luminescent, dielectric, optoelectronic, electrochemical, mechanical, and barrier applications, with a focus on layered compounds (including but not limited to metal phosphates, silicates, layered double hydroxides, graphene/graphite, MXenes, perovskites, and their derivatives, etc.)

Quantum‐confined 2D CsPbBr3 nanosheets are employed to investigate their exciton dissociation behavior. Tunneling instead of resonant energy transfer as a dominant way of exciton dissociation contributes to a high charge transfer rate. (Yang, et al. Advanced Functional Materials 2018, 28, 1705908)

  • Wearable electronics and soft robotics

 

Mechanochromic thin films exhibit rapid and reversible changes in transparency, color, and patterns. (Zeng, et al. Nature Communications 2016, 7:11802)

 

Multi-color reversible photochromisms via tunable light dependent responses (Smith, et al. Matter 2020, 2, 680)
