Preparation method of photoelectric sensitive charged nanometer particles

Abstract

The invention relates to a preparation method of photoelectric sensitive charged nanometer particles, which belongs to the technical field of ultraviolet light polymerization or polymerization. The invention uses photoelectric sensitive monomers ion type monomers or ionizable monomers and flexible monomers capable of automatically triggering the cross linking through ultraviolet irradiation for co-polymerization to obtain a photoelectric sensitive ion type polymer, and a self assembly method is used for preparing the photoelectric sensitive charged nanometer particles with the self triggering capability capable of being used for electric field inducing film formation. The photoelectric sensitive charged nanometer particles have water solubility. Because the photoelectric sensitive charged nanometer particles does not need additionally added light triggering agents and has good long-time stability, the photoelectric sensitive charged nanometer particles can be used for preparing molecular engram identification films, aqueous cathode / anode electrophoresis photocureable paint and photosensitive particles used for printing plates, and can also be used for nanometer particle inkjet printing. The photoelectric sensitive charged nanometer particles have good stability, low-temperature fast curing capability and environment-friendly performance.

Description

technical field A method for preparing photosensitive charged nanoparticles. The invention relates to a photosensitive charged nanoparticle, which is suitable for molecular imprint recognition sensing film, water-based cathode / anode electrophoretic photocuring coating, photosensitive particles for printing plates, and Nanoparticle inkjet printing belongs to the field of ultraviolet light curing or polymerization technology. Background technique Molecularly imprinted recognition sensing membrane is a kind of molecular recognition sensor, which has the same recognition performance and selectivity as biosensors prepared by using natural antibodies. At the same time, it has high stability and weather resistance of polymers, which overcomes the environmental requirements of biosensors. Harsh, short shelf life, and high production costs, so it has more practical application value. However, the current preparation methods of molecularly imprinted recognition sensing membranes are ...

Problems solved by technology

The effective imprinting rate of the molecularly imprinted recognition sensing membrane obtained by these two methods, the thickness control of the membrane, and the reproducibility of membrane preparation are difficult to control.

In addition, a certain amount of photoinitiator must be added to the UV photosensitive resin emulsion used in water-based cathodic / anodic electrophoretic photocuring coatings, photosensitive particles for printing plates, and photosensitive nanoparticle inkjet printing, but this brings Defects in the long-term stability of resin emulsions; at the same time, in some application fields of UV-curable coatings, such as food packaging, medical equipment, and dental materials, the added photoinitiator will inevitably bring certain harm due to its small molecule migration characteristics sex
