Competitive strategic development of a novel detachable bonding technology

拟议的战略研究项目建立了西蒙弗雷泽大学（SFU）的研究人员和支持组织之间的合作，以开发一种创新的粘合技术。支持组织对粘合材料有关键的战略需求，这种材料可以快速有效地将便携式设备附着在不同成分和粗糙度的表面上，并且在设备移除时不会留下粘合材料的痕迹。这个战略项目中提出的粘合技术的灵感来自于自然界中存在的一种解决方案：壁虎的干粘合。壁虎的脚趾上有柔顺的微纳米结构，这使它们能够附着在许多不同的表面上，爬上墙壁和天花板。目前还没有一种工程（合成）干式粘合剂可以经济有效地制造出与壁虎具有相同粘附强度的粘合剂，并且在相同种类的表面粗糙度和成分上表现得像壁虎一样好。因此，我们提出了一种全新的干胶粘剂制造工艺，这将使干胶粘剂的制造能够同时粘在粗糙的表面上，可以在大片上制造，并且制造成本低廉。该项目符合NSERC战略目标领域3，制造业的标准，因为它侧重于开发新的和有竞争力的技术进步，在材料设计和制造方面，以及开发具有成本效益的制造工艺，以提高灵活性和稳定性

The proposed Strategic Research Project establishes collaboration between researchers at Simon Fraser University (SFU) and the supporting organizations to develop an innovative bonding technology. The supporting organizations have a critical and strategic need for a bonding material that allows quick and efficient attachment of portable devices to surfaces with different compositions and roughness, and that leaves no trace of the bonding material when the device is removed. The bonding technology proposed in this Strategic Project takes its inspiration from - and further enhances - a solution present in nature: a gecko's dry adhesion. Geckos have compliant micro and nano structures on their toes, which allow them to attach to many different surfaces and crawl up walls and across ceilings. Currently there are no engineered (synthetic) dry adhesives that can be manufactured cost-effectively to have the same adhesion strength as a gecko and perform as well as a gecko on the same large variety of surface roughness and composition. We therefore propose a completely new manufacturing process for dry adhesives, which will enable fabrication of dry adhesives that can simultaneously stick to rough surfaces, can be fabricated in large sheets, and are inexpensive to manufacture. This project meets the criteria of the NSERC Strategic Target Area 3, Manufacturing, since it focuses on the development of new and competitive technological advancements in material design and fabrication and on the development of cost-effective manufacturing processes for improved flexibility and
