A photoinitiator is a chemical substance that can initiate a chemical reaction under the influence of light. It is commonly used in the preparation of polymers, dyes, catalysts, and other high-molecular-weight compounds.
What is a photoinitiator?
A photoinitiator is a chemical substance that can cause reactants to undergo a chemical reaction under the influence of light. Photoinitiators have a specific effect on light and only function as catalysts under light irradiation; they are harmless in the absence of light.
Types and Applications of Photoinitiators There are three common types of photoinitiators: aromatic ketones, disulfides, and organic peroxides. These photoinitiators can exert their catalytic effects under various environments and conditions, and have wide applications in the preparation of polymers, dyes, catalysts, and other high-molecular-weight compounds. In photocuring technology, photoinitiators can be used in UV adhesives, inks, coatings, 3D printing, etc. In biomedicine, photoinitiators are also frequently used to prepare novel biomedical materials. Furthermore, photoinitiators can also be used in purification, drug synthesis, oxidation reactions, and other fields.
