Precise Design of Organic/Inorganic Nano-Composite Films

nano-composite carbon nitride films

A modified cathodic arc technique has been used to deposit carbon nitride thin films directly on n Si substrates. Transmission Electron Microscopy showed that clusters of fullerene-like nanoparticles are embedded in the deposited material. Field emission in vacuum from as-grown films starts at an electric field strength of 3.8 V/μm. When the films were etched in an HF:NH4F solution for ten minu...

Antifungal activity of nano-composite films based on Poly Lactic Acid

Objective(s): Nanocomposite active packaging systems were used to prepare antimicrobial and antifungal properties. This study was to investigate the physical and antimicrobial activity of prepared films against three types of aflatoxin producing fungi Aspergillus Flavus. Material and methods: For investigating the effect of antibacterial nano-covers, the direct contact of 0, 1%, 3% and 5%...

Mechanical Coating Technique for Composite Films and Composite Photocatalyst Films

SAXS of self-assembled oriented lamellar nano- composite films: an advanced method of evaluation

Oriented lamellar nanocomposites formed of alternating organic and inorganic layers were prepared by evaporation-induced self-assembly and studied by small-angle X-ray scattering in symmetrical and asymmetrical re ̄ection. Analytical expressions were used for a quantitative ®t of the experimental data. The ®tting procedure leads to a comprehensive characterization of the lamellar two-phase syste...
