Ultraviolet-Assisted Modified Delignified Wood with High Transparency

The substrate of solar cells with high haze, transparent, flexible, green and low coatings will be needed in the future. This paper reports a method for ultraviolet-assisted delignification wood an alkaline solution environment to improve transmittance “transparent wood”. Scanning electron microscope (SEM), X-ray diffraction image (XRD), Fourier transform infrared (FTIR) spectroscopy transmittance-haze chemical composition analysis were used explore mechanisms underlying effect lignin modification on optical properties results show that UV-assisted accelerates rate removal chromogenic groups, which turn improves wood”, 2 h increasing light transmission wood” by 20%. 4 impregnation resulted transparency 71% haze 90%. report provides rapid easy prepare high-quality is potential candidate transparent substrates. Meanwhile, this enlightening quality, fast preparation other derived functional materials based wood.
