Abstract

Red-pigmented photoselective polymethylmethacrylate (PMMA) films were prepared by casting from polymer/chloroform solution. The films were doped with efficient red fluorescent perylene dyes specialized for plastic coloration, namely KREMER 94720 and KREMER 94739, which have excellent weathering stability and a high fluorescence quantum yield. The effect of the doping concentration was studied using the atomic force microscope (AFM), optical transmission, color measurement, time-resolved fluorescence, and Fourier transform infrared spectroscopy (FTIR). The obtained results suggested the potential usefulness for photoselective greenhouse cladding applications as the lowest doping concentration (10 wt%) displaying the UV-open effect, whereas the best UV-blocking and thermic effects were obtained for the highest doping concentration (10 wt).

摘要

通过从聚合物/氯仿溶液中浇铸制备了红色颜料光选择性聚甲基丙烯酸甲酯（PMMA）薄膜。这些薄膜掺杂了专门用于塑料着色的高效红色荧光苝染料，即科莱恩94720和科莱恩94739，它们具有优异的耐候稳定性和高荧光量子产率。使用原子力显微镜（AFM）、光透射、颜色测量、时间分辨荧光和傅里叶变换红外光谱（FTIR）研究了掺杂浓度的影响。所得结果表明，作为显示紫外线开放效应的最低掺杂浓度（10 wt%），其在光选择性温室覆盖应用中具有潜在用途，而最高掺杂浓度（10 wt）则获得了最佳的紫外线阻挡和热效应。
