FIG. 10 SEM micrographs of (a) sUica nanoparticle/polymer [Si02/PDADMAC)3]-coated PS lat-ices and (b) hollow silica capsules. The hollow sUica capsules were obtained by calcining coated particles as shown in (a). The calcination process removes the PS core and the polymer bridging the silica nanoparticles, while at the same time fusing the silica nanoparticles together. Some of the silica capsules were deliberately broken to demonstrate that they were hollow (b). (From Ref. 106.)... 

FIG. 13 TEM micrograph of a hollow composite nanoparticle/polymer capsule dried on a carbon grid. The hollow composite capsule was obtained after removal of the ME core from Si02/PDAD-MAC-coated ME particles by treatment with hydrochloric acid. The shadowing seen is a result of collapse and overlapping of the hollow capsule upon drying. (From Ref. 110.)...

Highly structured, 3-D nanoparticle-polymer nanocomposites possess unique magnetic, electronic, and optical properties that differ from individual entities, providing new systems for the creation of nanodevices and biosensors (Murray et al. 2000 Shipway et al. 2000). The choice of assembly interactions is a key issue in order to obtain complete control over the thermodynamics of the assembled system. The introduction of reversible hydrogen bonding and flexible linear polymers into the bricks and mortar concept gave rise to system formation in near-equilibrium conditions, providing well-defined stmctures.

Due to the presence of the ionic P4VP-Re-complex block on the film surface, nanoparticles decorated with anionic functional groups can be deposited on the copolymer film surface by electrostatic attraction. The copolymer film was immersed into a solution of cadmium sulfide nanoparticles (diameter = 10 nm), functionalized with carboxylate groups on the particle surface. The attachment of cadmium sulfide nanoparticles on the film surface was confirmed by X-ray photoelectron spectroscopy (XPS). In addition, particles deposited on the cylindrical blocks in the copolymer film surface were also observed in AFM image (Figure 5.12). This approach has potential in fabricating nanoparticle-polymer composites on patterned surface.

The goal of this chapter is to present an overview of reports in the scientific literature that involve the use of microwave heating in the preparation of inorganic and organometallic compounds. For practical purposes, no attanpt has been made to cover compounds of all elements. The scope has been limited to coordination compounds and organometallic complexes containing transition metals. The focus is on molecular compounds and not on materials that could be classified as nanoparticles, polymers, supported catalysts, metal-organic frameworks, or solid-state materials.
