Embodiment

[0038] Preparation of multi-walled carbon nanotube nanohybrid nonlinear optical functional material MWCNT-SnTPP1 axially covalently functionalized with organic transition metal tin porphyrin (SnTPP1):

[0039]The pre-prepared MWCNTs (50 mg) was ultrasonically dispersed in 50 mL of DMF solution for 30 minutes, and then 50 mg of SnTPP1 was added to the dispersion system; sarcosine (600 mg) was added in three times, once every 24 hours, and reacted at 150 ° C under nitrogen protection for 6 sky. After the reaction, the reaction solution was cooled to room temperature, 150 mL of deionized water was added thereto, and then the reaction solution was filtered with a 0.45 μm nylon membrane, and then washed with deionized water, methanol, dichloromethane and anhydrous ether, Then dried overnight in vacuum to obtain multi-walled carbon nanotubes MWCNT-SnTPP1 axially covalently functionalized with organotransition metal tin porphyrins.

Abstract

The invention belongs to the field of war-industry high-power-laser protective materials, and particularly relates to an organic-transition-metal tin-porphyrin axial covalent functionalization multiwalled-carbon-nanotube nano-hybrided nonlinear optical function material with good nonlinear absorption performance and a preparing method thereof. According to the material and the preparing method, organic-transition-metal tin porphyrin is axially connected to the surfaces of multiwalled carbon nanotubes in a covalent bond mode through 1,3-dipole cycloaddition; due to the synergistic effect between the tin porphyrin and the multiwalled carbon nanotubes, the solubility, the dispersion stability and the nonlinear optical absorption performance of the multiwalled carbon nanotubes are improved, and the scheme is not simple physical mixing of the two different optical function materials. The prepared nonlinear optical function material has quite good solubility and quite good dispersion stability in organic polar solvents, and has quite high nonlinear optical absorption performance, and therefore the organic-inorganic nano-hybrided nonlinear optical function material shows important scientific research value and good practical application prospects.

Description

technical field [0001] The invention belongs to the field of strong laser protection materials for military industry, and specifically relates to the synthesis of organic transition metal tin porphyrin axially covalently functionalized multi-walled carbon nanotube nano-hybrid nonlinear optical functional material and its third-order nonlinear optical absorption performance. Background technique [0002] Since the invention of strong light sources based on laser principles in 1960, strong laser technology has been widely used in the field of military technology as an important means of modern high-tech warfare. Among all kinds of laser weapons, Western countries have begun to research and apply high-energy laser interference and blinding weapons since the 1980s. With the development and actual equipment of such strong laser weapons, the protection of optical devices sensitive to strong light, especially the human eye, has attracted great attention. As one of the important la...
