Embodiment Construction
[0025] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.
[0026] Oligomer PTB: Under nitrogen atmosphere, compound 1 (38 mmol, 31.561 g) and compound 2 (50.67 mmol, 18.648 g) were added into a three-necked flask. Then add the catalyst PdCl 2 (PPh 3 ) 2 (1.01mmol, 711mg) and the solvent DMF 200mL, and gradually raised the temperature to 110°C and stirred for 12h. After the reaction was completed and cooled to room temperature, the reaction liquid was sunk into methanol solution, and the resulting solid was collected with filter paper. The crude product was dissolved with a certain amount of chloroform and filtered, and then the filtrate was spin-dried. The resulting viscous solid was washed with a large amount of hot n-hexane to obtain the final product PTB with a yield of about 96%.
[0027] Oligomer Ni-PTB: Under a nitrogen atmosphere, add polymer PTB, a cer...

Abstract
The invention belongs to the technical field of high-performance polymer materials, and relates to a bimetallic complex containing polymer coating with an infrared optical characteristic, and a preparation method and an application of the polymer coating. The method comprises the steps of synthesizing a nickel complex sulfo-diolefin oligomer precursor via metal coupling for Schiff base curing andmetal complexing reaction, and performing infrared and microwave absorption performance testing on the prepared coating. The bimetallic complex containing polymer coating has near-infrared absorbability, lower middle and far infrared emitting ability and microwave compatible stealth performance. The coating has excellent solubility in common organic solvents. The coating has a self film-forming property and can be prepared into a near-infrared absorption film with excellent mechanical properties through solvent processing. The coating can be blended with an inorganic filler to form a visible light visibility and infrared compatible stealth functional coating. The preparation method of the coating is simple and mild in reaction condition, and the prepared coating has a practical applicationvalue in the field of infrared stealth.
Description
technical field [0001] The invention belongs to the field of high-performance polymer materials, and relates to a polymer coating containing bimetallic coordination with infrared optical properties and a preparation method thereof. The nickel-coordinated thiodiene oligomer precursor was synthesized by metal coupling, Schiff base curing and metal coordination reaction were carried out on the precursor, and the infrared and microwave absorption properties of the prepared coating were tested. Background technique [0002] Infrared is an electromagnetic wave. According to its characteristic wavelength, the infrared region can generally be subdivided into three regions: the far-infrared region is 50-500 μm, the mid-infrared region is 2.5-50 μm and the near-infrared region is 0.78-2.5 μm. Near-infrared absorbing dyes are one of the research hotspots in the field of chemical and chemical dyes in recent years. For example, half of the solar radiation energy is mainly concentrated i...
