Opportunity:
Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its use of VACNT films to develop scalable, electrochromic devices that can modulate the transmission/absorption/reflection or emission of visible/infrared radiation.
Background:
Materials capable of modulating the propagation or emission of light from surfaces, both in the visible and infrared, are of interest for displays (televisions, tablets, billboards), optical telecommunications, and radiative thermal management in residential, industrial, and commercial buildings. Previous research demonstrated the effects of electrical bias or electrolytic gating on the absorption/transmission/emission of infrared radiation with carbon nanotube-based devices. These prior demonstrations often use mats/sheets consisting of randomly-oriented, typically flat-lying carbon nanotubes (CNTs), which is disadvantageous since poor control of the orientation leads to poor control over the optical response of the device.
Description:
LLNL inventors have developed an electrochromic device containing Vertically Aligned single walled CNTs (VACNTs) with a range of diameters. The assembly of these devices into electrochromic windows filled with ionic liquid allows for reversible modulation of the Fermi level in the VACNT film. These electrochromic devices show strong voltage-dependent transmission of near-infrared radiation. They can potentially be fabricated into large-area windows which modulate the flow of infrared heat into buildings among other applications.
Advantages/Benefits:
The demonstrated, non-optimized electrochromic performance showing a maximum change in transmittance at
1.7 micrometers IR wavelength of 47%. Potential ... - Documents:
