SBIR Phase I: Dry Nano Adhesive Based on Carbon Nanotubes

小企业创新研究(SBIR)第一阶段项目将开发一种灵活、可重复使用、双面、干燥、导热和导电的胶粘剂薄膜，由嵌入柔性聚合物基质的致密垂直排列的多壁碳纳米管(CNT)组成。被选为基质的聚合物是对二甲苯。碳纳米管从聚合物基质中突出，形成活性粘接界面。当薄膜附着在靶面上时，碳纳米管与靶面之间会产生显著的范德华(VDW)引力。VDW粘接不受真空或湿度的影响，不需要施加压力，因此可以提供普遍有效的粘接机制。因此，建议的产品可以用作许多其他不太方便的紧固件和夹具的替代品，由于其易于使用和更优化的设计，因此节省了时间和金钱。

The Small Business Innovation Research (SBIR) Phase I Project will develop a flexible, reusable, two-sided, dry, thermally and electrically conductive adhesive film consisting of a dense vertically aligned multiwalled carbon nanotubes (CNT) embedded in a flexible polymer matrix. The polymer chosen as the matrix is Parylene. The CNTs protrude from the polymer matrix to form an active adhesive interface. When the film is attached to a target surface, significant van der Waals (vdW) attraction occurs between the CNTs and the target surface. The vdW adhesion is unaffected by vacuum or moisture, does not require applied pressure and, therefore, can provide a universally effective adhesion mechanism. Consequently, the proposed product can be used as a replacement for many other and less convenient kinds of fasteners and fixtures, saving time and money due to its ease of use and more optimal design..
