The disclosure discloses a phosphorus-nitrogen-zinc two-dimensional supramolecular coated molybdenum disulfide hybrid flame retardant and application thereof, and belongs to the technical field of halogen-free flame retardant. Components of the phosphorus-nitrogen-zinc two-dimensional supramolecular coated molybdenum disulfide hybrid material in the disclosure include, by weight, 1-2 parts of molybdenum disulfide, 1-1.5 parts of zinc salt, 5-8 parts of a nitrogen-containing compound and 5-10 parts of a phosphorus-containing compound. As a flame retardant, the hybrid material of the disclosure effectively exerts an organic-inorganic synergistic flame retardant effect; the flame retardant efficiency of molybdenum disulfide is improved; the addition amount of the flame retardant in a matrix is reduced; the mechanical properties of the matrix can be improved at the same time; and the material has a very good application prospect.

Disclosed is a method for detecting aflatoxin B1 based on fluorescent copper nanoparticles, belonging to the technical fields of analytical chemistry, materials science and nano biosensing. In the disclosure, &#x3b2;-CD@DNA-Cu NMs are prepared by using Y-shaped DNA as a template, ascorbic acid as a reducing agent and &#x3b2;-CD as a fluorescence stabilizing and enhancing agent. Then, a ratiometric fluorescent probe is constructed based on the &#x3b2;-CD@DNA-Cu NMs. Finally, the detection of AFB1 with high sensitivity, high selectivity and high accuracy is achieved by using the fluorescent probe. According to the method of the disclosure, in linear ranges of 0.03-10 ppb and 10-18 ppb, a ratio value of Inm/Inm and a concentration of AFB1 exhibit a good linear relationship respectively, and a limit of detection is 0.012 ppb (S/N=3). Metal ions Camay be replaced with Yb, Y, Erand Pt, which are also suitable for increasing sensitivity of AFB1 in rice.

Disclosed is a method for preparing self-dispersing nano carbon black based on a thiol-ene click reaction. A sol-gel technique is used to graft a coupling agent containing a carbon-carbon double bond onto the surface of the carbon black, and a functional molecular chain is grafted onto the surface of the carbon black by a thiol-ene click reaction with a mercapto compound. The self-dispersing nano carbon black is obtained after centrifugation, washing and drying. The method is simple and easy to operate, has a high grafting rate, and can prepare self-dispersing nano carbon black adaptable to different systems by selecting mercapto compounds with different functional groups.

The present invention provides a novel pretreating agent to improve the effect of ink-jet printing on polyester fabric and its application, and this invention belongs to the field of digital ink-jet printing. Stirring the dispersing agent, which includes many procedures of wetting agent and deionized water in a stirrer, adding nano-porous oxide dispersoid. Furthermore, keep stirring for 30 min and put the mixture in a sand mill to grinded for 2 h, then nano-porous oxide dispersoid is eventually got. The nano-porous oxide dispersoid work as pretreating agent, which used in the polyester fabric, is treated like pretreating agent during the padding process. By applying this technique into double-sided permeation ink-jet printing and direct-injection ink-jet printing, its pattern's definition, color depth and color saturation could be remarkable enhanced. This method has many advantages such as the craft is easy to handle as well as the operation is simplified, it is also suitable for batch production of the polyester fabric.
