Scientific Research

 I Research interests

(1) High energy-storage dielectrics: High-energy storage dielectrics for high-power capacitors are widely used in UHV, rail transit, aerospace detection, pulsed power equipment and other fields. Through the design and synthesis of the main/side chain structure of organic macromolecules, the adjustment of the phase state and surface characteristics of inorganic particles, different intermolecular forces (van der Waals force/hydrogen bond/covalent bond) are constructed between heterogeneous phases. Revealing the coupling law and electrical characteristics between different phases and clarify the structure-performance relationship of high energy storage dielectrics.

(2) Flexible piezoelectric sensorsStudy the structure-performance relationship of materials in the process of mechanical-electricity, thermal-electricity conversion, reveal the polarization behavior, response mechanism and energy conversion principle of materials, design and preparation of flexible sensor devices which can be used for intelligent sensing, pressure evaluation, etc.  

(3) High-performance packaging materials: Polymers and composite materials with advanced electrical functions are widely used in military and civilian fields such as aerospace, power electronics and chip manufacturing. The characteristics of ultra-low loss, thermal conductivity, high temperature resistance, and low stress will be investigated for the basic principles and application basis of packaging materials.
