Research Summary

WE ARE BROADLY INTERESTED IN DEVELOPING new chemical, physical, engineering, and biological applications related to self-assembled nanostructured materials. Our current research is focused on the following four topics:

SELF-ASSEMBLED PHOTONIC & PLASMONIC CRYSTALS Photonic crystals and plasmonic crystals offer unprecedented opportunities for the realization of all-optical integrated circuits and high-speed optical computation. Our group is developing a number of scalable colloidal self-assembly technologies to control, manipulate, and amplify light on the sub-wavelength scale. We are also involved in the fabrication, characterization, and modeling of a large variety of functional nanooptical and plasmonic devices enabled by the bottom-up approaches.

BIOMIMETIC BROADBAND ANTIREFLECTION COATINGS By mimicking the nanostructured antireflection layer on the cornea of a moth and the water-shedding coating on the wings of a cicada, we are developing self-cleaning broadband antireflection coatings for a wide spectrum of applications ranging from highly efficient solar cells and light emitting diodes to high-sensitivity spectroscopy for space exploration. Once again, we are interested in scalable nanomanufacturing technologies that can be inexpensively applied to large areas.

NOVEL STIMULI-RESPONSIVE SHAPE MEMORY POLYMERS By integrating scientific principles drawn from two disparate fields—the fast-growing photonic crystal and shape memory polymer (SMP) technologies, we have developed a new type of shape memory polymer (SMP) that enables unusual “cold” programming and instantaneous shape recovery triggered by applying a large variety of unconventional stimuli (e.g., static pressure, vapors, and shear stress) at ambient conditions. These new stimuli-responsive SMPs differ greatly from currently available SMPs as they enable orders of magnitude faster response and room-temperature operations for the entire shape memory cycle. We are now exploring the broad applications of these smart materials in detecting Weapons of Mass Destruction (WMD) materials and aerospace morphing structures.

SMART WINDOW COATINGS FOR ENERGY-EFFICIENT BUILDINGS Windows are typically regarded as a less energy efficient building component, and they contribute about 30 percent of overall building heating and cooling loads. We are developing a transformative dynamic window technology that enables dynamic and independent control of visible and near infrared light and eliminates expensive transparent conductors in the final devices. The innovative dynamic windows are inspired by the mature heat pipe and photonic crystal technologies, which have been widely used in controlling the flow of heat and light, respectively.
