This Small Business Innovation Research (SBIR) Phase II project presents novel technology to fabricate dry, removable, reusable adhesives based on aligned polymeric nanofibers using scalable electrospinning methodologies. This new approach offers the potential advantages of significantly lower costs and easier scale-up using nozzle-free nanofiber spinning processes. Dry reusable adhesives as a replacement for messy liquid glues will improve product safety and reduce environmental impact. Removable and reusable adhesive tapes and labels will also eliminate waste and facilitate product recycling. The resulting products will have strong shear adhesion and easy peel, leading to broad application with a wide range of substrates like glass, metal, wall board, and plastics. Proof-of-concept samples have confirmed market-driven value propositions. The Phase II project will develop commercial products and applications for consumer and industrial applications, for automotive assembly systems, for decorative wall murals, and for medical device and health care uses. Fiber spinning and collection techniques will be engineered to improve product performance, reduce costs and improve scalability of the manufacturing process.The Phase I project has confirmed proof-of-concept dry adhesive samples with shear adhesion strengths exceeding 20 N/cm2 in dynamic mode and 45 N/cm2 in dead weight mode. The resulting samples have low peel strength and are reusable. In Phase II, the electrospinning process will be optimized using novel polymer blend systems to achieve performance targets for specific customer product development. The nozzleless electrospinning process will be scaled to the pilot level for product testing and to provide the engineering design basis for commercial manufacture. A continuous roll-to-roll process to produce aligned nanofibers will break new ground in the electrospinning industry. New applications in medical devices have been proposed by strategic partners to capitalize on the self-adhesion properties of these materials. Dry adhesive applicator systems will be developed to allow the aligned adhesive nanofibers to conform to surface asperities. With the Phase I success of proof-of-concept prototypes, the Phase II effort will move the development of aligned nanofiber dry adhesives into the market introduction phase in preparation for commercial manufacture and sales.

这个小企业创新研究（SBIR）第二阶段项目提出了一种新技术，利用可扩展的静电纺丝方法，基于对齐的聚合物纳米纤维制造干燥，可拆卸，可重复使用的粘合剂。 这种新的方法提供了显着降低成本和更容易使用无纺纺丝工艺放大的潜在优势。干燥可重复使用的粘合剂作为混乱的液体胶水的替代品将提高产品安全性并减少对环境的影响。可重复使用的胶带和标签也将消除浪费，促进产品回收。所得产品将具有很强的剪切粘合力和易剥离性，从而导致广泛的应用范围广泛的基板，如玻璃，金属，墙板和塑料。概念验证样本证实了市场驱动的价值主张。二期项目将开发用于消费和工业应用、汽车装配系统、装饰壁画以及医疗器械和医疗保健用途的商业产品和应用。纤维纺丝和收集技术将被设计用于提高产品性能、降低成本和提高制造工艺的可扩展性。第一阶段项目已确认概念验证干胶样品的剪切粘合强度在动态模式下超过20 N/cm 2，在静重模式下超过45 N/cm 2。 所得样品具有低剥离强度并且可重复使用。在第二阶段，将使用新型聚合物共混体系优化静电纺丝工艺，以实现特定客户产品开发的性能目标。无纺静电纺丝工艺将扩大到中试水平，用于产品测试，并为商业生产提供工程设计基础。连续的卷对卷工艺生产排列的纳米纤维将在静电纺丝工业中开辟新天地。 战略合作伙伴已经提出了医疗器械中的新应用，以利用这些材料的自粘附特性。 将开发干粘合剂施加器系统以允许对齐的粘合剂纳米纤维符合表面粗糙度。随着第一阶段概念验证原型的成功，第二阶段的工作将把对齐的干胶的开发转移到市场引入阶段，为商业制造和销售做准备。
