Nano and Advanced Materials Institute Ltd | Date: 2017-01-16

Chemically and mechanically protective oxide film was formed on Mg alloys using micro-arc oxidation (MAO) methods. Further modification of the obtained MAO surfaces was made in various aspects and the processes thereof were described. Firstly, the protection is enhanced by forming super-hydrophobic surfaces, with water contact angle higher than 140, attributed to hierarchical nano-micro structures. Secondly, the electrical property of the MAO surfaces is modified. A film with sheet resistance as low as 0.05 /sq is achieved by electro-less Ni deposition on MAO surfaces. Thirdly, black colors are achieved by the sol-gel process on MAO samples.

A built-in and process-adaptive formulation of antimicrobial commodity thermoplastic resins with mixed compositions comprising of a polymer, a backbone linker, and a non-labile antifouling and biocompatible coupling agent which is melt-processable and enabled to be manufactured into finished products in the form of solid, monolith, tube, composite, fiber, film, sheet and varnish without the prerequisite of biocides or antimicrobial additives is disclosed. The said formulation is adapted to thermoforming and thermal curing processes including but not limited to melt compounding, spinning, extrusion, molding, compression foaming and drawing. The antimicrobial property is attributed to the persistent formation of a non-stick bacteria-repellent tethered layer in which the antifouling component of the said formulation is heterogeneously phase separated and/or surface migrated to the surface after product forming in order to minimize adsorption and/or colonization of bacteria.

Si/SiO_(2) core/shell nanostructures with sizes below 30nm as trapping points in UV curable hybrid organic-inorganic gate dielectrics are presented in order to investigate printable nano floating gate transistors. Not only does the novelty of this invention comes from fabricating high-quality hybrid organic/inorganic gate dielectric layer by Sol-Gel process at low temperature but also incorporating the monolayer of high-density of Si nanoparticles (NPs) without obvious interface defects and keeping the quality of dielectric layers. Fixed-charge trapping defects are successfully removed from hybrid dielectrics by UV curing together with low temperature thermal curing and mobile charges solely related to Si/SiO_(2) core/shell nanostructures on charge trapping layer clearly demonstrate memory effects on printable device. Thin/uniform SiO_(2) shell on each Si NP functions as tunneling layer of flash memory devices, significantly simplifying the fabrication of printable nano floating gate memory device.
