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. In general, 1 g of Ti 3 AlC 2 It was carefully added to 20 mL of hydrofluoric acid solution, and then stirred at 40° C. for 24 h. The obtained product was washed with deionized water and centrifuged 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 min, and the supernatant was removed and freeze-dried to obtain black fluffy Ti. 3 C 2 T x Nanosheets.

[0044] Step 2:

[0045] Commercially available tetrapyridyl porphyrin (100 mg) was dissolved in 20 mL of dry N,N-dimethylformamide solvent, 4 mL of methyl iodide was added, and th...

Abstract

The invention relates to a cationic porphyrin functionalized Ti 3 C 2 T x Nanosheet nonlinear nanohybrid material composed of cationic porphyrin TMPyP adsorbed on Ti via electrostatic interaction and its preparation and application 3 C 2 T x formed on the surface. Compared with the traditional technology, the present invention adsorbs TMPyP on Ti through electrostatic action. 3 C 2 T x Compared with traditional materials, the obtained materials have enhanced nonlinear optical properties in the nanosecond visible light and near-infrared fields, and have very broad 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 functionalized Ti 3 C 2 T x Nanosheet nonlinear nanohybrid materials and their preparation and applications. Background technique [0002] Since the invention of the strong light source based on the laser principle in 1960, strong laser technology, as an important means of modern high technology, has been widely used in civil, military and scientific and technological fields; The study of strong 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 and so on. In recent years, two-dimensional (2D) materials, such as graphene, molybdenum disulfide, antimony, phosphorus, etc., have attracted extensi...
