Abstract

The invention provides a preparation method of a PDMS and AAO double-layer embedded template for polymer film patterning. The preparation method comprises the following steps: firstly, preparing a PDMS solution; secondly, preparing an anodic aluminum oxide sheet by adopting a secondary anodic oxidation method, removing an aluminum sheet of an aluminum oxide film substrate, putting the AAO sheet into a phosphoric acid solution to form a through hole, and drying the AAO sheet to obtain a bi-pass AAO sheet; soaking the sheet in a PDMS solution and discharging bubbles; taking out the AAO sheet filled with the PDMS solution, scraping off the PDMS glue on one surface of the AAO sheet, enabling the surface to be in contact with tert-butyl alcohol, enabling the AAO sheet to float in the tert-butylalcohol solution for cleaning, taking out the AAO sheet of which one end is of a smooth hole structure, and then carrying out residual PDMS material cross-linking. The invention also provides an application of the PDMS and AAO double-layer embedded template. The template disclosed by the invention is simple to prepare and low in cost, has the advantages of a hard template and a soft template at the same time, and has a good application value.

Description

technical field [0001] The invention relates to the field of preparation of polymer patterned templates, in particular to a preparation method and application of a PDMS and AAO double-layer embedded template for polymer film patterning. Background technique [0002] With the development of nanotechnology and the in-depth study of functional polymer materials, the micro-nano patterning of polymer films has attracted extensive attention and attention. For example, the construction of polymer film nanopillar patterning is one of the important aspects. Compared with unpatterned polymer films, the construction of polymer nanopillar films exhibits a series of special material properties and potential applications, such as drug carriers, special active substrates, interface properties, optical properties, and optoelectronic properties. . Therefore, the performance optimization and application prospects of these functional materials are inseparable from the patterning process of p...
