Research Interests

Ferroelectric Polymers for Memories and Energy Utilization

"Ferroelectric polymer free-standing nanodot arrays with ultrahigh data storage density are reported by Qun-Dong Shen and co-workers on page 3124. The arrays are fabricated using nano-imprinting and the preferred orientation of the copolymer chains is favorable for polarization switching of single nanodots. Nanometer electronic features can be written directly in two dimensions using piezoresponse force microscopy probe based technology." Adv. Funct. Mater. 2013, 23, 3019

Rock engravings, cuneiform script, and woodblock printing are the earliest ways of recording and conveying information by making use of mechanical force. With proliferation of electronic data, traditional time-consuming ways become obsolete. We demonstrate flexible nonvolatile memory with storage density of tens to hundreds Gbit/in2 through manipulating electric polarization state of ferroelectric polymer by tiny force (less than 100nN).

Conjugated Polymers for Biological Applications

Water-soluble conjugated polymers are highly efficient at harvesting and emitting light energy. They can be used as bright fluorescent labels for imaging of biological cells and tissues. Based on the fluorescence signal modulation of the polymers in response to the analytes, it has driven interest in high-sensitive and rapid-response fluorescence biosensors.
