The research objective of this award is to develop a design methodology for optimal synthetic fibrillar adhesives inspired by gecko foot-hairs, to improve our detailed nanomechanical understanding of biologically inspired fiber array adhesion, and to fabricate and demonstrate hierarchical synthetic fibrillar adhesives similar to their biological counterparts. The research breakthrough proposed in this work is the development of a design methodology for the fabrication of hierarchical and high performance biologically inspired fibrillar adhesives using continuum theoretical nanomechanical models. These improved theoretical fibrillar nanomechanical models and fabricated synthetic multi-level fibrillar adhesives will advance research of biologically inspired adhesives and nanofiber adhesion, contact, and fracture mechanics and will produce new self-cleaning and repeatable adhesive commercial products in the near future.If successful, the results of this research will provide an opportunity to create new repeatable adhesive products in textile, biomedical, space, sports, entertainment, product design, robotics, and packaging industry. Interdisciplinary research work in this proposal will be transferred to many educational activities in mechanical engineering, biomedical engineering, and materials science. Micro/Nano-Robotics course developed by the principle investigator will use the biologically inspired adhesive and material concepts, models, and fabrication facilities in this project to design and implement new biologically inspired nanomaterials in student semester-long projects. The research results of this project will be disseminated to children, K-12 students and teachers, and college students through public lectures and summer internships. This project will train underrepresented graduate and undergraduate students in biologically inspired inspired nanomaterials and nanomechanics fields.

该奖项的研究目标是开发一种受壁虎脚毛启发的最佳合成原纤维粘合剂的设计方法，以提高我们对生物启发纤维阵列粘合的详细纳米力学理解，并制造和展示类似于其生物的分层合成原纤维粘合剂。同行。 这项工作提出的研究突破是开发一种使用连续理论纳米力学模型制造分层和高性能生物启发原纤维粘合剂的设计方法。 这些改进的理论原纤维纳米力学模型和制造的合成多级原纤维粘合剂将推进生物启发粘合剂和纳米纤维粘合、接触和断裂力学的研究，并将在不久的将来生产出新的自清洁和可重复的粘合剂商业产品。如果成功，这项研究的结果将为在纺织、生物医学、太空、体育、娱乐、产品设计、机器人和包装行业创造新的可重复粘合剂产品提供机会。 该提案中的跨学科研究工作将转移到机械工程、生物医学工程和材料科学领域的许多教育活动中。 由首席研究员开发的微/纳米机器人课程将在该项目中使用受生物启发的粘合剂和材料概念、模型和制造设施，在学生为期一个学期的项目中设计和实施新的受生物启发的纳米材料。 该项目的研究成果将通过公开讲座和暑期实习的方式向儿童、K-12学生和教师以及大学生传播。 该项目将在受生物启发的纳米材料和纳米力学领域培训代表性不足的研究生和本科生。
