effects of pulse voltage and deposition time on the Adhesion strength of graded metal carbon films deposited on bendable stainless steel foils by hybrid cathodic arc glow discharge plasma assisted chemical vapor deposition
Applied Surface Science, 2016Co-Authors: M Jamesh, R L Boxman, M M M Bilek, Cenk Kocer, Tingwei Hu, Xuming Zhang, D R MckenzieAbstract:Abstract Graded Ti/C composite films with carbon topcoats are prepared on bendable stainless steel foils by hybrid cathodic arc / glow discharge plasma-assisted chemical vapor deposition to simulate cardiovascular stents. Strong Adhesion between the stainless steel substrate and carbon topcoat is achieved due to the graded Ti/C interface and it is further improved by increasing the pulse voltage. Moreover, the graded coating is more hydrophilic than the stainless steel substrate.

graded metal carbon protein binding films prepared by hybrid cathodic arc glow discharge plasma assisted chemical vapor deposition
Surface & Coatings Technology, 2015Co-Authors: M Jamesh, R L Boxman, Neil J Nosworthy, I S Falconer, M M M Bilek, Alexey Kondyurin, R Ganesan, D R MckenzieAbstract:Abstract Graded composite layers containing metal and plasma polymer components were deposited using a cathodic arc in conjunction with plasma immersion ion implantation. Using a bias potential throughout, pure metal was deposited initially using the cathodic arc alone and then acetylene was added to the process to increase the fraction of the plasma polymerized carbon film. To test Adhesion, the substrate and film were Strongly deformed by folding the substrate inward and outward with a small radius of curvature. Strong Adhesion between the metal surface and the deposited layers was achieved by the use of the graded layers as inferred from the SEM observations of the deformation region. Strong Adhesion of biologically active protein molecules to the surface of the graded layer was confirmed by detergent washing and colorimetric enzyme activity assays. These characteristics suggest that the coatings may be suitable for cardiovascular stent applications.

printed highly conductive cu films with Strong Adhesion enabled by low energy photonic sintering on low tg flexible plastic substrate
Nanotechnology, 2017Co-Authors: Shuangshuang Shao, Zheng Chen, Zheng CuiAbstract:Copper (Cu) films and circuits were fabricated by screen-printing Cu nanoink on low-Tg (glass transition temperature) flexible plastic substrates (PEN and PET) instead of widely used high-Tg polyimide (PI) substrate. Photonic sintering of printed Cu films was carried out using intensive pulsed light (IPL). Low resistivities of 28 μΩ cm on PEN and 44 μΩ cm on PET were obtained without damaging the substrates. The sintered Cu films exhibited Strong Adhesion to PEN and PET substrates, with measured Adhesion strength of 5B by the ASTM D3359 international standard, whereas the top part of the copper film on the PI substrate was stripped off during the Adhesion test. The sintered Cu films also showed excellent stability in harsh conditions and mechanical flexibility in rolling tests. The underlying mechanisms of the high conductivity and Strong Adhesion on PEN and PET substrates with low-energy IPL sintering were investigated. Simple circuits and radio frequency identification antennas were made by screen-printing Cu nanoink and IPL sintering, demonstrating the technique's feasibility for practical applications.
