The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project will be to provide a new source of no-cost, pollution-free office paper. Despite advances in electronic displays society still uses tons of paper. Printing and copying remain ubiquitous. In 2013 the United States consumed 3.6 million tons of office copy paper, which according to the EPA?s Waste Reduction Model (WARM) added the equivalent of 28.4 million metric tons of carbon dioxide into the atmosphere. However, paper copies are only needed temporarily and most of that 3.6 million tons of paper is discarded or recycled within a few days. A reputed survey found that 21% of hardcopies are discarded the same day they are made. With the technology of Self-Erasing Inkjet Ink, the paper used for temporary hardcopies reverts to a blank sheet and can be re-used like new paper. In all subsequent uses the paper is pollution-free. For every 1% of the inkjet ink market captured by self-erasing ink, carbon emissions are reduced by 17 thousand metric tons per year, thereby supporting national goals of reducing pollution, conserving resources, and fighting climate change.The intellectual merit of this project lies in the development of a novel self-erasing ink for inkjet printing and photocopying. The water-based ink derives its color from an acid-base indicator which is dark blue in an alkaline solution but otherwise colorless. The ink is alkaline so it is colored when printed. After printing the ink begins to self-erase due to a neutralization reaction with carbon dioxide in the atmosphere. When the reaction is completed the ink is colorless and the paper appears as new. The project will leverage existing, unmodified inkjet printer/copiers and ink cartridges. This project will address remaining technical challenges in making the ink compatible with existing printers which were not designed for this type of ink chemistry. Specifically the project will determine how to ensure the ink does not clog the inkjet nozzles between infrequent printing sessions. The additives used for this purpose in conventional inks are not necessarily compatible with self-erasing ink chemistry and new ways to prevent clogging will be developed during the project. The anticipated results from this effort will be an ink that approximates the print quality and reliability of conventional ink but also self-erases.

这项小型企业创新研究（SBIR）I阶段项目的更广泛的影响/商业潜力将是提供新的无污染，无污染的办公论文的来源。尽管电子展示的进步，社会仍然使用大量纸。 打印和复制仍然无处不在。 2013年，美国消耗了360万吨的办公纸，根据EPA的废物减少模型（温暖），该纸将相当于2840万吨二氧化碳的二氧化碳加入了大气中。 但是，仅需暂时需要纸张副本，而在几天内将360万吨纸张丢弃或回收。 一项著名的调查发现，在制作同一天，有21％的硬皮被丢弃。 借助自我播放的喷墨墨水的技术，用于临时硬件的纸将其恢复为空白纸，并且可以像新纸一样被重新使用。 在随后的所有用途中，本文都是无污染的。 每年，每年1％的喷墨墨水市场中的每1％，碳排放量每年减少17000吨，从而支持减少污染，保护资源和抵抗气候变化的国家目标。该项目的智力优点在于开发新型的Inkjet Printing和Photocypopy和Photocypopy和Photocypopy和Photocypopy和Photocypopy和Photocypopy和Photocypopy和Photocypopy和Photocypopy和Photocypopy和Photocypopy和Photocypopy和Photocypopy的墨水。 水基墨水从碱性溶液中的酸碱指示剂中得出颜色，但无色。 墨水是碱性的，因此印刷时会涂色。 印刷后，由于与大气中的二氧化碳中和反应，墨水开始自我升压。 反应完成后，墨水无色，纸张出现为新。 该项目将利用现有的，未修改的喷墨打印机/复印机和墨盒。 该项目将解决与现有用于此类墨水化学的现有打印机兼容的剩余技术挑战。 具体而言，该项目将确定如何确保墨水不会在不经常打印会话之间堵塞喷墨喷嘴。 用于此目的的添加剂在传统墨水中不一定与自我空班的墨水化学兼容，并且在项目期间将开发防止堵塞的新方法。 这项工作的预期结果将是一个墨水，该墨水近似于传统墨水的印刷质量和可靠性，但也是自我搜索的。
