Application-directed syntheses of surface-functionalized organic and inorganic nanoparticles



An overview of the formation of inorganic and organic particles in emulsions is presented. The key aspect in these syntheses is the use of specially designed surface-active components. Examples of synthesis-driven approaches to various functional nanoparticles are illustrated. Surfmers based on isophthalic acid give access to particles for highly stabilized emulsions. Amphiphilic block copolymers as emulsifiers result in particles with excellent film-forming properties or which are applicable as supports for metallocenes. Amphiphilic statistical copolymers are used for the compatibilization of inorganic nanoparticles in hybrid materials. Block and statistical copolymers are versatile stabilizers of non-aqueous emulsions. In such systems nanoparticles obtained by either water-sensitive monomers or catalysts can be realized. Surface functionalization with aliphatic or aromatic amines results in latex particles, which are suitable as supports for postmetallocenes or as flocculants in the papermaking process. In each area, the incorporation of the amphiphiles at the nanoparticle surface is not only important for the particle formation itself, but also decisive for the applicability of the particles.
