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的，可重复使用的，双面的，干燥的，导热和导电的粘合剂薄膜，由嵌入柔性聚合物基质中的致密垂直排列的多壁碳纳米管（CNT）组成。选择作为基质的聚合物是聚对二甲苯。 CNT从聚合物基质突出以形成活性粘合剂界面。 当膜附着到目标表面时，在CNT和目标表面之间发生显著的货车范德华（vdW）吸引。 vdW粘合不受真空或湿气的影响，不需要施加压力，因此可以提供普遍有效的粘合机制。 因此，拟议的产品可用作许多其他不太方便的紧固件和固定装置的替代品，由于其易于使用和更优化的设计，可以节省时间和金钱。

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..
