Abstract

The invention belongs to the technical field related to manufacturing and processing, which discloses a selective adhesion transfer method based on laser surface treatment, the method comprising the following steps: (1) patterning the transferred film on the donor substrate Laser cutting to physically separate the transferred film into a patterned unit to be transferred and the remaining part, and at the same time use laser to ablate the surface of the remaining part, so that the transferred unit and the remaining part (2) adopting the stamp after viscosity adjustment to transfer the described transferred film, so that the transferred unit is selectively adhered to the surface of the stamp, and the remaining (3) printing of the transferred unit using the stamp on a dissolvable adhesive substrate so that the transferred unit is transferred from the stamp to the dissolvable adhesive on the base. The invention is efficient and simple, and can realize large-scale automatic operation.

Description

technical field [0001] The invention belongs to the technical field related to manufacturing and processing, and more specifically relates to a selective adhesion transfer printing method based on laser surface treatment. Background technique [0002] Transfer printing is a set of techniques for the definitive assembly of micro- and nanomaterials into spatially organized functional arrangements, with two- and three-dimensional layouts. These processes not only provide versatile avenues for test structures for scientific research, but also provide important avenues for high-performance, heterogeneously integrated functional systems, including flexible electronics, three-dimensional and / or curvilinear optoelectronics, and biointegrated sensing and therapeutic devices. [0003] However, the existing methods for forming a specific microstructure pattern on the donor substrate are complex and lack a controllable selective transfer mechanism during the transfer process. For this ...
