Abstract: Disclosed are a multilayer composite intumescent fire-retardant coating material, a preparation method therefor, and a method of using the same, relating to the technical field of intumescent fire-retardant coating materials. The coating material comprises a bottom fire-retardant coating material and a surface fire-retardant coating material, and a composite method is a single layer or presents an ABAB . . . type. The bottom fire-retardant coating material contains a physical expansive agent. The surface fire-retardant coating material contains a gas-foaming expansive agent. By fully utilizing the filling effect of the physical expansive agent and the expanding effect of the gas-foaming expansive agent, the size of pores formed in the expansion layer under the fire is substantially reduced, which not only improves the compactness and strength of the expansion layer but also improves the thermal insulation performance of the expansion layer.

Abstract: Provided are an organic rare-earth solid micelle, a preparation method therefor, and a method for increasing the photoelectric conversion efficiency of a solar battery. A small organic conjugated ligand is taken as a first ligand, an amphiphilic diblock polymer is taken as a second ligand, and the first ligand and the second ligand are mixed and doped with a rare-earth chloride solution, and self-assembled to form an organic rare-earth solid micelle, whereby the fluorescence emission intensity and the fluorescence efficiency of the rare-earth element are improved. Next, the prepared organic rare-earth solid micelle is spin coated on an ITO layer of a solar battery, to prepare a solar battery with the organic rare-earth solid micelle. Therefore the sunlight absorption of a cell is increased, and the photoelectric conversion efficiency is improved. The preparation process is simple, low in cost, high in photoelectric conversion efficiency, and environmentally friendly.
