The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project are two-folds. First, the novel ionic liquid lubricant developed will improve the reliability and areal density of Hard Disc Drives (HDDs), which has great impact in numerous applications involving information storage using electronic and consumer devices. Second, the proposed research will educate the next-generation of engineers with both engineering training and entrepreneurial mindsets and skills. The students, particularly female and underrepresented minority (URM) students, will take the entrepreneurial training, which provides them the in-depth knowledge on small business development and prepares them for future careers in entrepreneurship.The proposed project aims to close the technical gap to bring a novel ionic liquid lubricant to the market. In Heat-Assisted Magnetic Recording (HAMR), which is the next-generation HDD technology, media lubricant needs to have high thermal stability and high fly clearance. However, the state-of-the-art lubricant, i.e., perfluoropolyether (PFPE), is not thermally stable enough and has low fly clearance. In preliminary research, a novel ionic liquid lubricant has been developed and industrial tests showed it has the desired high thermal stability and fly clearance. In the proposed research, the plan is to: (1) improve the reaction yield to ~80% by optimizing the reaction time and temperature; (2) scale up the synthesis by ~20 times via a novel membrane-aided simultaneous reaction-separation process; and (3) conduct drive-level industry testing to fully qualify the ionic liquid lubricant. The novelty of the proposal lies on the following two aspects. First, the membrane-aided simultaneous reaction-separation makes large-volume production much more efficient. Second, the drive-level industry testing is expected to fully demonstrate the advantages of the ionic liquid lubricant with respect to the state-of-the-art PFPE lubricant, which will greatly advance the HDD technology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这种创新合作伙伴关系的更广泛的影响/商业潜力 - 技术翻译（PFI-TT）项目是两倍。首先，开发的新型离子液体润滑剂将提高硬盘驱动器（HDD）的可靠性和面积密度，该密度在涉及使用电子和消费者设备的信息存储的许多应用中产生了巨大影响。其次，拟议的研究将通过工程培训和企业家心态和技能来教育工程师的下一代。学生，尤其是女性和代表性不足的少数群体（URM）学生，将接受企业家培训，这为他们提供了有关小型企业发展的深入知识，并为他们为企业家的未来职业做好了准备。拟议的项目旨在缩小技术差距，以将新颖的离子液体润滑剂带到市场上。在下一代HDD技术的热辅助磁记录（HAMR）中，培养基润滑剂需要具有较高的热稳定性和高苍蝇间隙。但是，最先进的润滑剂，即全氟po（PFPE），不够热稳定，并且具有较低的蝇率。在初步研究中，已经开发了一种新型的离子液体润滑剂，工业测试表明它具有所需的高热稳定性和苍蝇间隙。 在拟议的研究中，计划是：（1）通过优化反应时间和温度，将反应产量提高到〜80％； （2）通过新型的膜辅助反应分离过程将合成规模约20倍； （3）进行驱动水平的行业测试，以充分鉴定离子液体润滑剂。该提案的新颖性在于以下两个方面。首先，膜辅助的同时反应分离使大容量的产生效率更高。其次，预计驱动水平的行业测试将充分证明离子液体润滑剂在最先进的PFPE润滑剂方面的优势，该奖励将极大地推进HDD技术。该奖项反映了NSF的法定任务，并认为通过基金会的知识优点和广泛的crietia crietia crietia criperia criperia criperia criperia criperia criperia criperia criperia均值得通过评估。
