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，以开发创新的粘接技术。支持组织迫切需要一种粘合材料，该粘合材料能够快速有效地将便携式设备连接到具有不同成分和粗糙度的表面，并且在移除该设备时不会留下粘合材料的痕迹。这个战略项目中提出的粘接技术的灵感来自于并进一步增强了自然界中存在的一种解决方案：壁虎的干粘附力。壁虎的脚趾上有顺从的微型和纳米结构，这使得它们可以附着在许多不同的表面上，并沿着墙壁和天花板爬行。目前，还没有经过改造的(合成)干胶，可以经济高效地制造，使其具有与壁虎相同的粘合强度，并在相同种类的表面粗糙度和成分上表现出与壁虎一样的性能。因此，我们提出了一种全新的干胶制造工艺，这将使干胶的制造能够同时粘在粗糙的表面上，可以制造成大片，并且制造成本低廉。该项目符合NSERC战略目标区域3，制造业的标准，因为它侧重于在材料设计和制造方面开发具有竞争力的新技术进步，并开发具有成本效益的制造工艺，以提高灵活性和

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
