Problems solved by technology

Nowadays, in the surface treatment of nanoimprinting, photolithography, inkjet printing and other technologies, micro-nano structures with high aspect ratios have high application value, but for this kind of micro-nano structures that are not easy to manufacture, how to quickly and effectively The manufacture of the
[0003] At present, the hydrophobic coating on the surface of the substrate and the nano-pattern on the surface of the substrate are mostly used to realize the high-thickness-width-ratio micro-nano structure. Due to different ink material systems, there are different material coatings and micro-nano pattern processing, the process is cumbersome, and the thickness-width ratio is difficult to control.

Abstract

The invention discloses a method and device for manufacturing a micro-nano structure with a high thickness-width ratio, and belongs to the field of flexible electron manufacturing. The method specifically comprises the steps of applying an electric field to a micro-nano liquid drop pattern that is printed on a substrate in a spraying manner, transversely shrinking and longitudinally stretching theedge of the micro-nano liquid drop pattern to form the micro-nano structure with the high-thickness-width-ratio. The device comprises an upper electrode plate, a lower electrode plate and an externalhigh-voltage amplifier system, the wire connecting ends of the upper electrode plate and the lower electrode plate are respectively connected with the external high-voltage amplifier system, and during working, the substrate on which the micro-nano liquid drop pattern is printed is placed on the lower electrode plate, the external high-voltage amplifier system is started between the upper electrode plate and the lower electrode plate to form the electric field, and the edge of the micro-nano liquid drop pattern is shrunk transversely and stretched longitudinally to form the micro-nano structure with the high-thickness-width-ratio. According to the present invention, the micro-nano pattern with the high thickness-width ratio is generated through electric field induction, the manufacturingefficiency of the micro-nano structure is remarkably improved, and the precision requirement is met.
