specific Embodiment approach 1

[0033] Specific implementation mode 1: Optical clipping C in this implementation mode 60 The preparation method of / POSS composite film is carried out according to the following steps:

[0034] 1. Preparation of POSS sol: Mix formic acid solution, ethanol and silane coupling agent in a mass ratio of 1:3:3, and then react in a water bath at 35°C for one week to prepare POSS sol;

[0035] Second, the synthesis of intermediates:

[0036] Will C 60 Dissolved in an organic solvent to obtain a concentration of 1g / L of C 60 solution, the C 60 The solution is mixed with the POSS sol according to the ratio of 1ml:1g, and then the mixture is heated in a water bath at 80°C for 0.5-1 hour to obtain the intermediate;

[0037] 3. Compounding of intermediate and matrix:

[0038] According to the mass ratio of intermediate, POSS sol and matrix of 1:4:3, mix the intermediate, POSS sol and matrix evenly to obtain a mixed solution, and then apply the mixed solution evenly on the glass surfac...

Abstract

The invention provides a preparation method of an optical amplitude limiting C60 / POSS (Polyhedral Oligomeric Silsesquioxane) composite film and relates to a preparation method of a composite film. The invention aims to solve the technical problems that C60 taken as an optical amplitude limiting material is lower in dissolubility, and the optically nonlinear properties are reduced. The preparation method comprises the following steps of: 1, preparing POSS sol; 2, synthesizing a midbody; and 3, compounding the midbody and a substrate. The preparation method has the beneficial effects that the C60 is connected with POSS together by utilizing a group containing an amino group to realize the property superposition of the C60 and the POSS; and a synthesized product has good film forming property and high transparency and can be used as a coating film on an optical device.

Description

technical field [0001] The invention relates to a preparation method of a composite membrane. Background technique [0002] Laser has excellent properties such as high monochromaticity, high directivity and high coherence, so it has a wide range of applications in communication, ranging, guidance, radar, etc. Laser weapons are a new milestone after cold weapons, firearms, and nuclear weapons. Laser jamming and blinding weapons have been applied in Western countries, and they will surely shine in the 21st century. This type of weapon mainly destroys ground military installations and blinds military personnel, achieving the purpose of making the opponent lose combat effectiveness. With the rapid development of modern laser technology, more and more attention has been paid to laser protection. Various optical limiting materials containing large π conjugated systems, such as fullerenes, phthalocyanines, porphyrins, stilbene derivatives, organometallic compounds, etc. It has be...
