The invention relates to a textile which is equipped with a biocidal substance. The textile according to the invention is characterized in that 2-n-octyl-4-isothazoline-3-on is contained as the biocidal substance and optionally one or more other biocides, and in that the biocidal substance is embedded in aminoplastic resin microparticles. By embedding the biocidal substance in the microparticles the biocidal substance remains on the textile during drying and condensation while the textile is finished. In practice, the biocidal substance is released only slowly and is not washed out when the textile is exposed to rain or soaked, thereby preventing the biocidal substance from escaping largely already when the textile is finished or preventing it from being washed out from canvas, awnings, filters, tarpaulin, shower curtains and the like after a few downpours.

The invention discloses a water body clarifying agent capable of improving the water body self-purifying capacity.The water body clarifying agent is prepared from, by weight, 24-25 parts of silkworm excrement, 13-15 parts of molasses, 1.4-1.6 parts of a nitrifying bacterium microbial agent, 3.3-3.5 parts of a bacillus subtilis microbial agent, 2-3 parts of sodium polyacrylate, 3-4 parts of ferric citrate, 0.4-0.5 part of microcrystalline cellulose, 65-66 parts of sunflower heads, 2.1-2.3 parts of ferroferric oxide powder, 25-27 parts of a ferrous oxalate solution with the concentration of 0.1 mol/L, an appropriate of an acetic acid solution and an appropriate of water.According to the water body clarifying agent, the community structure of beneficial bacteria in a water body is enriched through the microbial agent additives, therefore, a fermentation reaction of protein in excessive quantity of organic substances in the water body is achieved, and harmless decomposition of sludge is achieved; in addition, secreted floccules in the microbial metabolism process and contaminants in the water body form molecular groups to be settled, and then the water body self-purifying purpose is achieved.

The invention relates to a drug-loaded fiber ring and a preparation method and application thereof. The method comprises preparing a DOX/PLGA drug-loaded nanofiber membrane by electrospinning, and homogenizing to obtain the DOX/PLGA drug-loaded fiber ring. The surface is subjected to hyperbranched PEI chelating Gd(III) for MR imaging, and a modified DNA aptamer acts as a targeting molecule to be tightly bound to cancer cells, which can effectively inhibit tumor metastasis and invasion. The preparation method has the advantages of simple preparation process and good material biosafety. The ringmaterial is more likely to anchor the cancer cells and reduce the shedding of tumor cells. An internally loaded drug can effectively act on the tumor tissues for a long time, and effectively inhibitthe metastasis while killing the cancer cells. The fiber ring has broad application prospects in the field of cancer treatment.

The invention relates to a side-group long-chain azidated epoxy resin and a synthesis technique thereof. By controlling the addition amount of azide, reaction temperature, reaction time and other conditions, the long-chain azido group is grafted on the hydroxy group of the epoxy resin to prepare the side-group long-chain azido epoxy resin. The azido group can form strong coordinate bond with the metal atoms of the substrate, thereby effectively enhancing the adhesive force of the coating for the metal substrate. Meanwhile, the side-group long chain has high hydrophobic action, and thus, is capable of effectively eliminating the water content on the substrate surface in the curing process and enhancing the adhesive force of the coating on the wet metal substrate surface by 90% or so. The side-group long-chain azidated epoxy resin can be used for developing the anticorrosive paint for wet metal substrate surfaces with higher adhesive force, better shielding performance and long effective period, and can provide an effective technical way for development of underwater construction anticorrosive paints.
