In transparent conductive electrodes using silver nanowire (AgNW) networks, regions with and without AgNWs exhibit different optical properties. This phenomenon, known as “pattern visibility,” is typically undesirable. In this study, the intrinsic optical properties – absorption, scattering and extinction – of AgNW/polymer composite films are derived from transmission and reflection spectra measured using an integrating sphere. These spectra reveal two major properties of AgNWs: transverse mode extinction due to localized surface plasmon resonance in the near-ultraviolet region, and longitudinal mode extinction in the visible to near-infrared region. By comparing AgNW/polymer composite films with similar sheet resistance, we find that composite films with smaller AgNW diameters show large absorption in the near-ultraviolet region, but limited scattering over the entire wavelength region, despite large amounts of AgNWs. We also show that pattern visibility is reduced for composite films with smaller AgNW diameters, which exhibit a smaller color difference ΔE00 (CIEDE2000) between the regions with and without AgNWs, when applied to the diffuse reflection spectra.
The study deals with the automatic measuring path generation of 3-dimensional measuring machine (3 D-CMM) with 5 degrees of freedom. The 3 D-CMM consists of the Cartesian coordinate structure and a touch probe with 2 rotational degrees of freedom. The measuring path is automatically generated in off-line on the basis of CAD, taking account of the collision between the touch probe and workpieces. The measuring path is converted to the actual one by matching the CAD data with the image of workpiece being arbitrarily set on the 3 D-CMM. The system enables the measurement without changing the setting of workpieces, which remarkably reduces the measuring time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
