Abstract

The days of rewritable paper are coming, printers of the future will use water-jet paper. Although several kinds of rewritable paper have been reported, practical usage of them is rare. Herein, a new rewritable paper for ink-free printing is proposed and demonstrated successfully by using water as the sole trigger to switch hydrochromic dyes on solid media. Water-jet prints with various colours are achieved with a commercial desktop printer based on these hydrochromic rewritable papers. The prints can be erased and rewritten dozens of times with no significant loss in colour quality. This rewritable paper is promising in that it can serve an eco-friendly information display to meet the increasing global needs for environmental protection.

摘要

可重复书写纸的时代即将到来，未来的打印机将使用喷墨纸。尽管已经报道了几种可重复书写的纸张，但它们的实际应用却很少。在此，我们提出并成功演示了一种新的、用于无墨打印的可重复书写纸，它仅使用水作为唯一的触发手段在固体介质上切换变色染料。基于这些可重复书写的变色纸，我们使用商用台式打印机实现了各种颜色的喷墨打印。这些打印件可以被擦除和重写几十次，而不会对颜色质量造成明显损失。这种可重复书写纸很有前景，因为它可以作为一种环保的信息显示材料，以满足全球日益增长的环保需求。
