姜黄素的一个明显的局限性是它不能达到深的颜色深度，这是由姜黄素的低超临界二氧化碳溶解度引起的。本研究在姜黄素中引入烷基（乙基、丁基、己基或辛基）以获得更好的溶解性和染色能力。结果表明，烷基化后姜黄素的溶解性和染色性均有所提高。在二甲基亚砜（DMSO）存在下，丁基姜黄素对蚕丝的染色效果最好。这种现象不仅与丁基姜黄素的高溶解度密切相关，而且与超临界二氧化碳和二甲基亚砜的协同作用导致的丝的比表面积增加密切相关。
An obvious limitation of curcumin is its inability to achieve a deep color depth, which is caused by curcumin's low supercritical carbon dioxide solubility. In this study, alkyl groups (ethyl, butyl, hexyl or octyl) were introduced to curcumin to achieve better solubility and dyeing ability. The results showed that both the solubility and dyeing ability of curcumin increased after alkyl grafting. The best dyeing ability was achieved by using butyl curcumin to dye silk in the presence of dimethylsulfoxide (DMSO). This phenomenon is closely related not only to the high solubility of butyl curcumin but also to the increase in the silk specific surface area, resulting from the synergistic effects of supercritical carbon dioxide and dimethylsulfoxide.
