The Particle Functionalization Process

The functionalization of particles with CDI typically involves several steps. First, particles are prepared through either physical or chemical methods. Common materials used for particles include silica, polystyrene, and other polymers.

Next, the CDI is activated, which generally involves dissolving it in a suitable solvent. The particle suspension is then treated with the activated CDI, allowing it to react with any hydroxyl or carboxylic groups present on the particle surface. This reaction leads to the attachment of CDI to the particle.

Finally, the amine compounds are introduced. This step results in the formation of stable amide bonds, effectively functionalizing the particle’s surface. Post-reaction, the particles are usually washed to remove any unreacted CDI or byproducts before a final characterization.

Advantages of CDI Amine Functionalization
