Reports Summarize Materials Science Findings from School of Materials Science and Engineering

June 24, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- New research on Materials Science is the subject of a report. According to news originating from Atlanta, Georgia, by VerticalNews correspondents, research stated, "Although synthetic efforts have been fruitful in coarse color control, variations to an electrochromic polymer (ECP) backbone are less likely to allow for the fine control necessary to access the variations and shades of color needed in display applications. Through the use of thin films of cyan, magenta, and yellow ECPs, non-emissive subtractive color mixing allows the color of an electrochromic device (ECD) to be selected and tailored, increasing access to various subtle shades and allowing for a non-emissive display to exhibit a wide range of colors."

Our news journalists obtained a quote from the research from the School of Materials Science and Engineering, "Using a dual-active ECD, subtractive color mixing utilizing the cyan magenta yellow (CMY) primary system was examined. The bounds of the gamut, or the subset of accessible colors, using these three 3,4-propylenedioxythiophene (PProDOT)-derived materials in combination with the recently recognized 3,4-propylenedioxypyrrole-based minimally color changing polymer (MCCP) were mapped, highlighting the benefit of applying subtractive color mixing toward the development of full-color non-emissive displays."

According to the news editors, the research concluded: "Here, we demonstrate that ECPs are suitable for the generation of a wide gamut of colors through secondary mixing when layered as two distinct films, exhibiting both vibrantly colored and highly transmissive states."
