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.

这项小型企业创新研究（SBIR）II期项目提出了新技术，以使用可扩展的静电纺丝方法来基于对齐的聚合物纳米纤维制造干燥，可移动，可重复使用的粘合剂。 这种新方法提供了使用无喷嘴纳米纤维旋转过程明显降低成本和更容易扩展的潜在优势。可重复使用的粘合剂作为凌乱的液态胶水的替代将提高产品安全性并减少环境影响。可移动和可重复使用的胶带和标签也将消除浪费并促进产品回收。所得的产品将具有较强的剪切粘附力和易于剥离，从而通过玻璃，金属，壁板和塑料等广泛的底物进行广泛的应用。概念验证样本已确认市场驱动的价值主张。第二阶段项目将开发用于消费者和工业应用，汽车装配系统，装饰壁壁画以及医疗设备和医疗保健用途的商业产品和应用。纤维旋转和收集技术将经过设计，以提高产品性能，降低成本并提高制造过程的可伸缩性。I期项目已确认在动态模式和动态模式下，具有超过20 N/CM2的概念验证干燥粘合剂样品45 N/cm2处于静重模式下。 所得的样品具有低剥离强度，可重复使用。在第二阶段，将使用新型聚合物混合系统进行优化静电纺丝过程，以实现特定客户产品开发的性能目标。虚无的静电纺丝过程将缩放到用于产品测试的试点水平，并为商业制造提供工程设计基础。一个连续的滚动过程以生产一致的纳米纤维将在电纺上产生新的地面。 战略合作伙伴已经提出了医疗设备中的新应用，以利用这些材料的自粘特性。 将开发干粘合剂涂抹器系统，以使对齐的粘合剂纳米纤维能够符合表面浅层。随着概念证明原型的第一阶段成功，第二阶段的努力将使对齐的纳米纤维干胶的开发进入市场介绍阶段，以准备商业制造和销售。
