南唐时期，河北墨工奚超南迁到安徽歙县，取当地的大松为原料，制成的墨“黝黑发光、入纸不晕、历久不衰”。受到南唐后主李煜赏识，赐其国姓“李”。从此，徽州李墨便名扬天下，有“黄金易得，李墨难求”之誉。
出自于宋人何薳 《墨记》
在南唐时期，墨绝对算的上是当时的“顶流”了。

时光飞逝，书写工具的多样化让墨产生了‘危机感’，也许是时候做些改变了......

前方记者带到消息：“据悉，昔日价值千金的顶流墨现身化学院门口，疑似整形。”本台将持续为您跟踪报道。

传送带缓缓启动，随着距离的越来越近，大放光彩的墨以全新的形式360度无死角地展现着自己的美。

咔嚓咔嚓，多家报社的拍照声不绝于耳......

化学，让我成为更好的自己。墨如此说道

LANGMUIR上团队Jianming Yang, Hongqiang Wang, Bin Zhou, Jun Shen, Zhihua Zhang, Ai Du合作完成的关于Versatile Direct Writing of Aerogel-Based Sol–Gel Inks

文章摘要：Direct ink writing (DIW) of aerogels has great potential in designing novel three-dimensional (3D) multifunctional materials with hierarchical structures ranging from the nanoscale to the macroscopic scale. In this paper, pure aerogels composed of inorganics, strongly cross-linking organics, and weakly cross-linking organics were directly written via the precise control of the gelation degree without using any additives. The rheological properties of a resorcinol–formaldehyde aerogel-based sol–gel ink (marked as RA ink) were measured at different reaction times to determine the suitable printable range (G′LVR: several 103 Pa) that ensures its good print fidelity. In addition, the rheological evolution of the RA ink during the sol–gel process and under different shear stresses was studied. The correlation of relevant parameters was established according to the Hagen–Poiseuille model. Other typical aerogel-based sol–gel inks including a silica aerogel-based sol–gel ink (SA ink) and a polyimide aerogel-based sol–gel ink (PA ink) for DIW were also demonstrated. Finally, water evaporation experiments were carried out using a 3D-printed carbonized resorcinol–formaldehyde aerogel (CA) to further exhibit the potential applications of this novel technology in solar steam generation. The evaporation rate (1.57 kg m–2 h–1) and efficiency (88.38%) of 3D-printed CA were higher than those of bulk CA (1.21 kg m–2 h–1 and 69.82%). This paper systematically studies the control of DIW parameters for aerogel-based sol–gel inks and shows a potential application in high-efficiency 3D-printed evaporators.
