摘要： A light-colored polycarboxylated polysaccharide tanning agent, and a preparation method and use thereof are provided. The light-colored polycarboxylated polysaccharide tanning agent includes the following raw materials: a polysaccharide, an organic solvent, a catalyst, and hydrogen peroxide. Based on a weight of the polysaccharide, a weight of the organic solvent accounts for 1 wt % to 15 wt %, a weight of the catalyst accounts for 0.05 wt % to 2 wt %, and a weight of the hydrogen peroxide accounts for 30 wt % to 80 wt %. The preparation method provided by the present disclosure adopts a two-phase solution system. Compared with the existing preparation technologies, the preparation method of the present disclosure can efficiently extract and remove colored substances produced during an oxidation process, and can timely block a polymerization reaction of the colored substances with an oxidized polysaccharide, such as to significantly reduce a chromaticity of an oxidized product.

摘要： An anti-biofouling shape-memory composite aerogel includes a unidirectional chitosan aerogel channel, a plant polyphenol coating, and a polyphenol/iron ion chelate. The plant polyphenol coating is evenly distributed on an inner wall of the unidirectional chitosan aerogel channel, and the polyphenol/iron ion chelate is located at a top end of the unidirectional chitosan aerogel channel. The anti-biofouling chitosan-based composite aerogel has an evaporation rate of 1.96 kg·m−2·h−1 at an illumination intensity of 1 kW/m2. The composite aerogel has shape-memory properties, and can quickly restore its original shape in water after extrusion, thereby accelerating the diffusion of substances to complete the modification of inner channels. In this way, desirable anti-biofouling ability is achieved, and excellent structural stability as well as continuous and efficient photothermal water evaporation are guaranteed in a complex water environment.

摘要： A coating material is allowed to contain a sulfate having a higher degree of solubility in water than that of calcium sulfate. The sulfate is an additive for coating materials which is used for reducing the consumption of zinc (including zinc oxide) in a coating film formed from the coating material and the corrosion of a base material when the coating film is scratched. The content of the sulfate can be 0.004 to 0.65 mol per 100 g of the content of zinc. Alternatively, the content of the sulfate may be 0.006 to 0.186 mol per 100 g of a heating residue (except for the sulfate added) of a coating film.
