Embodiment 1

[0044]

[0045] 1. Preparation of a phase-separated structure: Dissolving the polymerized block polymer 1 in an organic solvent solution such as toluene or tetrahydrofuran to obtain a homogeneous clear solution, which is fully dissolved and then filtered. Polymer thin films are formed on clean substrates by methods such as spin coating or bar coating. After the polymer film is annealed, a regular and ordered nano phase separation structure can be obtained. The structure typically has a diameter of 5-30 nanometers with a period of 10-100 nanometers. The distribution structure generally has a strip or point shape. As the main object of rapid regulation, the strip distribution is alternately arranged in parallel between different phases. The specific shape is as follows Figure 5 (a), Image 6 (a) shown.

Abstract

The invention discloses a preparation and fast light control method for a nano pattern based on an organic polymer. The nano pattern with an accurate structure is formed by self assembly at first by using a segmented copolymer having photo-induced isomerization property, then photoresponse functional groups of the segmented copolymer are made to generate photo-induced isomerization by ultraviolet or specific wavelength light irradiation and other means, and a nano phase separation structure is driven to generate fast change to acquire the stable and accurately arranged nano pattern, so as to achieve the accurate controllability of the nano pattern. The method is fast to regulate and control, accurate and reversible, and has a very wide application prospect in optics, microelectronics, physics, chemistry, material science and other fields.

Description

technical field [0001] The invention provides a method for preparing and rapidly adjusting regular nano-patterns based on organic polymer materials, and belongs to the field of organic polymer and nano-material science. Background technique [0002] Organic polymer materials often involve the fields of chemistry and materials. In recent years, with the continuous development of related fields and the deepening and expansion of scientific research work, people's understanding of this direction has become clearer. On this basis, a large number of applications have been developed by using the rich structure and special properties of organic polymers. Block copolymers are a very important class of organic polymers, which can be used to prepare versatile functional materials by utilizing the differentiated properties of different chains in the polymer. In the case of a relatively large difference in the properties of the two materials, after annealing treatment and other proces...
