This invention discloses a tensile-strength steel-cored aluminum stranded wire, relating to the technical field of steel-cored aluminum stranded wire. The tensile-strength steel-cored aluminum stranded wire of this invention comprises at least: a steel core; a Zn-Ni-WC composite coating, electroplated on the steel core; aluminum strands, stranded on the steel core coated with the Zn-Ni-WC composite coating; and an anti-corrosion coating applied to the stranded aluminum strands. The anti-corrosion coating comprises the following raw materials in parts by weight: 60-70 parts of long-chain modified polyurethane acrylate prepolymer; 25-30 parts of acrylate isoborneol ester; 15-20 parts of dopamine-modified sustained-release microcapsules; 2-5 parts of photoinitiator; 0.5-1.5 parts of leveling agent; and 0.5-1.5 parts of dispersant. This invention, by setting a Zn-Ni-WC composite coating on the steel core and an anti-corrosion coating on the steel-cored aluminum strands, enables the prepared tensile-strength steel-cored aluminum stranded wire to possess superior corrosion resistance and ultra-long-term tensile strength retention.

The invention provides a quantum dot film patterning method and application. The quantum dot film patterning method comprises the following steps: (1) mixing quantum dots with a photosensitive cross-linking agent to form a thin layer; (2) carrying out patterning exposure treatment on the thin layer to obtain a patterned quantum dot thin film; wherein ligands containing carbon-hydrogen bonds are arranged on the surfaces of the quantum dots; the photosensitive cross-linking agent has a structure as shown in a formula I: # imgabs0 #, wherein R1 is an electron donating group; n > = 2; x is a group which does not affect generation of a singlet intermediate. The quantum dot film patterning method can realize efficient patterning of different types of formed quantum dots in the air, has the advantages of high resolution, strong universality and suitability for large-scale industrial production, can be used for preparing photoelectric devices such as quantum dot LEDs and the like, and can maintain the photoelectric property of the quantum dot material to a greater extent.
