Abstract Nanomaterials and nanotechnology have been hot issues during the recent decades. This thesis deals with the fabrication and engineering of novel nanomaterials with enhanced functionality， particularly nanocomposites and nanostructured surfaces. The study includes two parts; in the first part， bulk transparent polymer-inorganic nanocomposites were produced by a novel synthesis method and its UV-absorption has been investigated. In the second part， nanostructured microporous surface layers， of copper， were fabricated by electrodeposition process and its effect on material’s performance for pool boiling has been investigated evaluated.In the first part of the thesis， bulk polymer-inorganic nanocomposites composed of poly(methylmethacrylate) (PMMA) and zinc compounds were prepared by an in situ sol-gel transition polymerization of zinc complex in PMMA matrix. The immiscibility of heterophases of solid organic and inorganic constituents was resolved by the in situ sol-gel transition polymerization of ZnO nanofillers within PMMA in the presence of dual functional agent， monoethanolamine， which provided strong secondary interfacial interactions for both complexing and crosslinking of constituents. Comprehensive characterization of the polymer-inorganic hybrid materials has been undertaken using a wide range of techniques; XRD， 1H NMR， FT-IR， TGA， DSC， UV-Vis， ED， SEM， TEM and HRTEM. The homogeneous PMMA-ZnO nanocomposites exhibited enhanced UV-sheltering effects in the entire UV range even at very low ZnO content of 0.02 wt%. 展開(kāi)
