Lacquer is a natural paint with excellent water and chemical resistance. It has long been known that adding a very small amount of iron into raw lacquer produces a very beautiful black color called Shikoku. However, the structure and reactions of lacquer are still largely unknown, and the reason of black color is also unclear. In this study, we analyzed the structure of raw lacquer and black lacquer films by using different kind of quantum beams. As a result, black lacquer has a completely different nanostructure from raw lacquer, and that the color changes depending on the difference in the structure. This result is the first successful analysis of the structure of the lacquer film, which had been a mystery for many years. This commentary describes this research and also explains how this research has been proceeded.

The small- and wide-angle neutron scattering instrument (TAIKAN) was installed in the Materials and Life Science Experimental Facility (MLF) of J-PARC, which was designed for efficient measurement in the range from sub-nanometre to micrometre scale. Therefor, TAIKAN is used in various research fields. Recently, the morphology of ion exchange membranes for fuel cells have been much studied using SAXS and WAXS techniques under high-temperature and high-humidity conditions close to the product usage environment. In this study, we measured the humidity dependence of the Nafion film structure at 80
C using a Humidity Cell at BL15 TAIKAN. As a result, it was possible to measure the humidity dependence of the matrix, ionomer, and crystal phase in the film. In this presentation, we will report the details of those results, and also report on the development status of TAIKAN.
