    "Optically tunable haze film" project accomplished by Jae Yeol Park

     

    Carbon, 96, 805–811, 2016

     

    Transparent, flexible composite films with switchable haze are presented that respond stably and rapidly to applied bias. The composite film is based on the laminated structure of all flexible materials, such as the polyethylene terephthalate substrate, graphene, paraffin-polydimethylsiloxane (P-PDMS) organogel, and PDMS overlayer stacked in order. Upon applying a bias, the graphene is Joule-heated...read more

     

     

    "Thermobattery" project accomplished by Kyoung Min Bae

     

    International Journal of Precision Engineering and Manufacturing, 16, 1245-1250, 2015

     

    We report a thermobattery that can efficiently harvest low-grade waste heat.Simple and scalable dipping and drying process was applied to prepare the SWNT coated textile electrodes (SWNT-CT). The SWNT coating not only decreases the sheet conductance of the textile remarkably but also provides the number of available reaction sites for thermogalvanic conversion, resulting in improving electrical outputs...read more

     

    "Tubing shaped thermal energy harvester" project accomplished by Hee Doo Yang

     

    Carbon, 86, 118–123, 2015

     

    A tubing-shaped, flexible electrochemical thermal energy harvester, which can be wound around various types of waste heat sources, was fabricated. The thermocell utilizes the temperature dependence of the ferri/ferrocyanide redox potential, providing a thermoelectric coefficient of ~1.4 mV/K. A highly porous carbon nanotube sheet, which is wrapped onto a thin platinum wire, was used as an electrode...read more

     

    "Self-powered humidity sensor" project accomplished by Hyoung Kyu Kim

     

    ACS Applied Materials & Interfaces, 6(11), 8320–8326, 2014

     

    We reports self-powered humidity sensors based on graphene oxide (GO) and poly(sodium 4-styrenesulfonate) (PSS)-intercalated GO composite films used as the humidity-responsive dielectrics. A hydrophilic and electrically-insulating PSS polymer was used as an intercalant between the individual GO platelets to enhance the water permeation...read more
