Problems solved by technology

Although this method can achieve fast immobilization of SRGs (usually 15 minutes), it usually requires high-intensity ultraviolet light irradiation, which will cause the degradation of azo polymer materials and the destruction of SRGs (H.Takase, A.Natansohn and P. Rochon, Polymer, 2003, 44, 7345-7351; T. Kimura, J.Y. Kim, T. Fukuda and H. Matsuda, Macromol. Chem. Phys., 2002, 203, 2344-2350; W. Li, S .Nagano and T.Seki, New J.Chem., 2009, 33, 1343-1348)

example 1

[0021] The HP-2 film with SRGs on the surface was immersed in a methanol solution of 1,6-hexamethylenediamine (concentration: 350mmol / L), reacted at 25°C for 15 minutes, and after taking it out, it was vacuum-dried to constant weight at room temperature to obtain Azopolymer thin films with immobilized SRGs.

example 2

[0023] The HP-6 film with SRGs on the surface was immersed in a methanol solution of 1,6-hexanediamine (concentration: 350mmol / L), and reacted at 25°C for 15 minutes. After taking it out, it was vacuum-dried at room temperature to constant weight to obtain Azopolymer thin films with immobilized SRGs.

example 3

[0025] The HP-10 film with SRGs on the surface was immersed in a methanol solution of 1,6-hexamethylenediamine (concentration: 350mmol / L), and reacted at 25°C for 15 minutes. After taking it out, it was vacuum-dried to constant weight at room temperature to obtain Azopolymer thin films with immobilized SRGs.

Abstract

The invention relates to a new fixing method of surface relief gratings on an azo polymer film. The fixing method of surface relief gratings on the azo polymer film is realized by introducing an N-hydroxy succinimide carboxylic ester group into an azo polymer and reacting with a diamine or polyamine solution. The fixing method for SRGs on the azo polymer film is mild in conditions, fast in speed and small in reaction system toxicity, the fixed SRGs structure is not influenced and has the advantages of good thermal stability and solvent resistance, and the like. The fixed surface relief gratings have wide application prospect in the fields such as optical storage, micro / nanofabrication, chemical sensors and the like.

Description

Technical field [0001] The invention relates to a new method for fixing surface relief gratings (Surface relief gratings, SRGs) on a polymer (abbreviated as azo polymer) film containing an azophenyl group, in particular to an azo polymer film A new method of chemical crosslinking by which SRGs on azo polymer films can be quickly and efficiently immobilized. Background technique [0002] As a photoresponsive functional polymer, azo polymer has excellent photoisomerization behavior of azobenzene molecules and good mechanical properties of polymer materials, so it has been shown in many fields such as optical switching devices, photodeformable materials and SRGs. a broad application prospect. Among them, the SRGs produced on the surface of the azo polymer film by irradiating two coherent laser beams with suitable wavelengths have important application value in the fields of optical storage, micro-nano processing and chemical sensors, so they are more and more popular. focus o...
