ABSTRACTOctafunctionalized silsesquioxanes [(RsiO1.5)8, cubes] offer potential as rigid, hard nanoplatforms to which a variety of organofunctional groups can be appended. Crosslinking these groups leads to novel organic/inorganic nanocomposites that consist primarily of interfacial interactions. These materials can be 100% interphase. We present efforts to develop nanocomposite materials that consist of both continuous and discontinuous organic/inorganic phases. We then discuss methods of probing the properties of these materials.

Morphological Investigations

ABSTRACTRealization of property enhancements inherent to the presence of nanoparticles continues to be a challenge for the production of bulk nanocomposite materials with commercially available techniques. This study combines twin-screw compounding with surface modification of SiO2 nanoparticles to enable targeted dispersion in a SEBS block copolymer. Production of these composites with high levels of well-dispersed particulates aims to leverage aggregation for production of hierarchical structure. The aggregation state of the particles as well as the level of order in the block copolymer morphology was determined through USAXS and TEM. Particles coated with ligands miscible with the end-blocks of the BCP (minority component) increased dispersion at all loading levels observed up to 10 vol%. Ligands employed to increase miscibility of the nanoparticle with the mid-block (majority component) resulted in large aggregates for all loadings without disturbance of the BCP morphology.

Many organic/inorganic nanocomposites have been fabricated into fibrous materials using electrospinning techniques, because electrospinning processes have many attractive advantages and the ability to produce relatively large-scale continuous films. In this study, the polyvinyl alcohol (PVA)/silk/titanium dioxide ( TiO 2) nanocomposite self-cleaning textiles were successfully produced using electrospinning technique. After optimizing electrospinning conditions, we successfully obtained the PVA/silk/ TiO 2 nanocomposite fibers with average diameter of ∼220 nm and TiO 2 concentration can be as high as 18.0 wt.%. For the case of the PVA/silk/ TiO 2 nanocomposite textile, the color of brilliant green coated on the textile surface changed from the initial green color to colorless after ultraviolet (UV) irradiation. Because of its worthy photocatalytic performance, the developed PVA/silk/ TiO 2 nanocomposite materials in this study will be beneficial for the design and fabrication of multifunctional fibers and textiles.

THE USE OF HYBRID OR NANOCOMPOSITE MATERIALS AS STEEL ANTICORROSIVE COATINGS. The search had as the goal to present and reflect the hybrid materials as an alternative for anticorrosive coatings of metallic surfaces, such as steel. For comparison purposes, different types of anti-corrosion coatings capable of protecting metallic surfaces, such as steel, from oxidation action were presented. Steel is a metallic material widely used by industry in different types of segments, and its corrosion is a pathology responsible for its functional loss, causing losses in its use. Through a qualitative, bibliographic and exploratory research, based on academic works, it was presented that hybrid materials or nanocomposites prove to be efficient as anticorrosive coatings capable of protecting steel against oxidation.
