Nanocomposites, materials of heterogeneous composition with at least one of the phases having dimensions between 1-100 nm, can be produced with unique properties dependent on their composition and geometric configuration. However, it is a major challenge to precisely and simultaneously design the structure of synthetic nanocomposites at the nanoscale, microscale, and macroscale. To create advanced nanocomposites in which both structure and composition can be programmed across these disparate size regimes, we have developed a new nanoparticle-based building block, the Nanocomposite Tecton (NCT). An NCT consists of an inorganic nanoparticle core and a polymeric shell, with each chain terminating in a supramolecular binding group at the periphery of the NCT.
As each NCT contains both an inorganic nanoparticle and a polymer phase, each building block is itself a nanocomposite, and the incorporation of supramolecular binding groups allows for the directed assembly of NCTs that contain complementary binding groups. These reversible supramolecular interactions enable the assembly of NCTs into ordered arrays, and the collective behavior of the binding groups can be regulated by the dynamics of the polymer chains. The NCTs are capable of rapidly self-assembling into several different crystalline phases that are determined by the design of the building block, and are resilient against dispersity in the molecular weight of the polymer brush and the diameter of the nanoparticle cores. NCTs have been synthesized with both gold and iron oxide nanoparticle cores, indicating the ability to produce NCTs at reasonable scales.
Moreover, the incorporation of multiple nanoparticle compositions allows for the synthesis of NCT-based materials with plasmonic and magnetic properties that can affect, as well as be affected by, the assembly process. We further demonstrate that the crystallization kinetics can be modulated to induce the assembly of NCTs into faceted crystallites with micron-sized diameters, and the resulting NCT crystallites can be post-processed into bulk solids with arbitrary macroscopic shape and controlled grain size. The NCT design concept is therefore a highly modular and versatile building block capable of fabricating materials with controlled structures at the levels of atomic composition and molecular geometry, nanoscale organization, microstructure, and macroscopic form.

This dissertation reports a simple route to synthesis nanostructured composites by immobilizing colloidal crystals (CCs) of monodisperse SiO2 spheres in crosslinked polymer network. The resulting ordered nanocomposites exhibited the highest modulus reported yet, to the best of our knowledge, for similar materials. The ordered nanocomposites were optically active and the Bragg diffracted light in a NIR region and wavelength of the Bragg peak could be tuned simply by changing the silica concentration in the composite. They also exhibited intense angle dependent iridescence.

In this investigation, we prepared more ordered polyaniline in the interlayer space of the layer materials and synthesized organic-inorganic nanocomposites by host-guest reactions. Infrared spectra and X-ray diffraction patterns showed that the organic guests are indeed insertedin the interlayer space of layer materials. The intercalation of anilinein HNbTiO5 and HNb3O8 results in two layers of aniline molecules in the interlayer space. When aniline was poly-merized to polyaniline, single layer polymer was formed. From the thermogravimetric analysis, we estimated the stoichiometries of these compounds are (C6H5NH3)0.31NbTiO5 , (C6H5NH3)0.72Nb3O8 , (PANI)0.17NbTiO5 and (PANI)0.14Nb3O8 .When V2O5 xerogel was reacted with furfuryl alcohol, PPV precursor and water-soluble poly-aniline, the interlayer space of V2O5 host increased 4 ~ 5 angstrom. The results implied that the aromatic rings of organic guests were parallel to the layer of the host. When V2O5 reacted with o-phenylenediamine, the guest molecules were polymerized to poly-o-phenylenediamine, and the resulting product was a biphasic structure. Some of the poly-o- phenylenediamine chains have their aromatic rings parallel to the layer of the host and some are perpendicular to the host layer. The shift of Infrared absorption peaks of guest moleculeinside the host is an additional evidence to prove that these organic guests are confined inthe restricted space. The stoichiometry of these nanocomposites is (FA)0.16V2O5 0.39H2O,( PDA)0.20V2O5 0.4H2O,(PPV precursor)0.28V2O5 1.2H2O and (PAPSANaH)0.13V2O5 0.79H2O respectively. The conductivity of these nanocomposites was quite different, ranged from 0.001 to 1 S/cm.
