Abstract: The present application relates to a mold for substrate surface functionalization. In the mold, a rubber strip is provided between an upper mold plate and a lower mold plate in a clamping manner, and a fastening structure enables the upper mold plate and the lower mold plate to clamp in opposite directions, such that the rubber strip, the upper mold plate and the lower mold plate form a mold cavity together under the action of a clamping force; and a positioning structure is used for fixing a substrate in the mold cavity, such that a pouring space is formed between at least one side surface of the substrate and the upper mold plate and/or the lower mold plate, the pouring space being used for pouring a modified material for surface functionalization of the substrate. The present invention further relates to a method for substrate surface functionalization.

Abstract: The present disclosure provides a detection method of wormlike micelles, and belongs to the technical field of analytical chemistry. In the present disclosure, z-ArN2+ is used as a chemical probe substance; a long-chain probe is added to a test solution for probing an interfacial region, and a short-chain probe is added to a surfactant-free control solution. A selectivity of the probe with different nucleophiles is determined by the above method, and a yield of an obtained product is measured by high-performance liquid chromatography (HPLC); and the wormlike micelles are detected by measuring the yield of the product using the selectivity of the short-chain probe to be converted into an interfacial mole number. The wormlike micelles are detected by chemical probes, and the chemical probes have a simple preparation method, a low cost, real-time detection, and broad prospects for use.
