In the history of civilization, Xuan paper with its superior texture, durability and suitable characteristics for writing and painting, has played an important role in the dissemination of culture and art. Xuan paper has won the reputation of "the king of paper that lasts for 1000 years" and was inscribed on the Representative List of the Intangible Cultural Heritage of Humanity by the Educational, Scientific and Cultural Organization of the United Nations in 2009. However, the surface of the commercial unprocessed Xuan paper has a large number of large-sized pores with a poor resistance to water, allowing ink droplets to easily spread during the writing and painting process. In this study, we report a new kind of nanocomposite Xuan (HNXP) paper comprising ultralong hydroxyapatite (HAP) nanowires and plant cellulose fibers with unique ink wetting performance, high whiteness and excellent durability. The as-prepared HNXP paper sheets with various weight ratios of ultralong HAP nanowires ranging from 10% to 100% are all superhydrophilic with a water contact angle of zero. In contrast, the ink contact angle of the HNXP paper can be well controlled by adjusting the weight ratio of ultralong HAP nanowires, and the ink contact angle of the HNXP paper increases with increasing weight ratio of ultralong HAP nanowires. The experimental results show the unique ink wetting behavior of the as-prepared HNXP paper, which is absent in the traditional Xuan paper. This new kind of nanocomposite Xuan paper comprising ultralong hydroxyapatite nanowires and plant cellulose fibers is promising for applications in calligraphy and painting arts.
在文明史上，宣纸凭借其卓越的质地、耐久性以及适合书写和绘画的特性，在文化和艺术传播中发挥了重要作用。宣纸赢得了“千年寿纸之王”的美誉，并于2009年被联合国教育、科学及文化组织列入人类非物质文化遗产代表作名录。然而，未经加工的商用宣纸表面有大量大尺寸孔隙，防水性差，使得墨滴在书写和绘画过程中容易扩散。在本研究中，我们报道了一种新型的纳米复合宣纸（HNXP），它由超长羟基磷灰石（HAP）纳米线和植物纤维素纤维组成，具有独特的墨水润湿性、高白度和优异的耐久性。所制备的超长HAP纳米线重量比在10%至100%之间的不同HNXP纸张均具有超亲水性，水接触角为零。相比之下，HNXP纸的墨水接触角可以通过调整超长HAP纳米线的重量比得到很好的控制，并且HNXP纸的墨水接触角随着超长HAP纳米线重量比的增加而增大。实验结果表明了所制备的HNXP纸具有独特的墨水润湿性，这在传统宣纸中是不存在的。这种由超长羟基磷灰石纳米线和植物纤维素纤维组成的新型纳米复合宣纸在书画艺术领域具有广阔的应用前景。
