Research Experience

Research Assistant, Rational Design of Advanced Polymer Dielectric Films,

MURI September 2011-present

Advisor: Dr. Gregory A. Sotzing Polymer Program, UConn, Storrs, CT

. Develop next generation dielectric materials for high energy density

capacitors in a multidisciplinary university research initiative (MURI)

project (http://faculty.ims.uconn.edu/MURI/index.htm). Collaborate with

researchers in seven groups and universities with different background

from modeling (DFT, molecular dynamics, chemoinformatics), to polymer

processing and electrical engineering.

. Develop new organic dielectrics including polyimides, polyureas,

polyurethanes and polythioureas through rationally designed synthesis and

thin film processing. Conduct systematic research on structure-property

relationships, achieving enhanced dielectric properties---high dielectric

constant, high breakdown strength, low dielectric loss and better thermal

durability. Optimize the process for large scale synthesis and polymer

film processing.

. Synthesis of organometallic polymers as dielectric material. Explore

chemical space of Group IV element-based hybrid polymers, especially

organotin polymers. Confirm intra- and inter-chain complex structures

through Infrared spectroscopy and X-ray diffraction. Achieve controlled

crystallization by polymer blending and layer-by-layer film processing.

. Collect and analyze data for polymer dielectric database combining

theoretical and experimental study; Establish figure of merit for polymer

dielectric material.
