Embodiment 1

[0041] Functionalized Ti based on cationic porphyrin 3 C 2 T x Preparation of nanosheet nonlinear nanohybrid materials, refer to figure 1 Shown:

[0042] first step:

[0043] Ti 3 C 2 T x Synthesis of Nanosheets. Generally, 1g of Ti 3 AlC 2 Carefully add 20 mL of hydrofluoric acid solution, then stir at 40° C. for 24 h, wash the obtained product with deionized water, and centrifuge at 8000 rpm for 5 minutes. This process takes several times until the pH of the supernatant becomes 6. The precipitate obtained by centrifugation was redispersed in deoxygenated deionized water, then the suspension was ultrasonicated for one hour, centrifuged at 3500 rpm for 45 minutes, and the supernatant was removed and freeze-dried to obtain a black fluffy Ti 3 C 2 T x Nanosheets.

[0044] Step two:

[0045] Commercially available tetrapyridyl porphyrin (100mg) was dissolved in dry 20mL N,N-dimethylformamide solvent, 4mL methyl iodide was added, the reaction was heated to 40°C, an...

Abstract

The invention relates to a cationic porphyrin functionalized Ti3C2Tx nanosheet nonlinear nano hybrid material as well as preparation and an application thereof. The nonlinear nano hybrid material is formed by adsorbing cationic porphyrin TMPyP on the surface of Ti3C2Tx through electrostatic interaction. Compared with the prior art, TMPyP is adsorbed on the surface of Ti3C2Tx through electrostatic interaction, the organic-inorganic covalent functionalized nano functional material is prepared, and compared with a traditional material, the prepared material has enhanced nonlinear optical performance in the fields of nanosecond visible light and near infrared and has very wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of organic-inorganic functional composite materials and military strong laser protection materials, and relates to a cationic porphyrin functional Ti 3 C 2 T x Nanosheet nonlinear nanohybrid materials and their preparation and application. Background technique [0002] Since the invention of strong light sources based on laser principles in 1960, strong laser technology has been widely used in civil, military and scientific fields as an important means of modern high-tech; The study of intense laser-sensitive materials in nonlinear optics has attracted great attention. There are many materials that can be used as nonlinear optics, such as organic materials, polymer materials, inorganic crystals, two-dimensional materials, etc. In recent years, two-dimensional (2D) materials, such as graphene, molybdenum disulfide, antimony, phosphorus, etc., have attracted extensive attention in the field of nonlinear op...
