Serigraphy

Polyamides can generally be decorated by painting, metallization, printing, flexography, offset, serigraphy, heliography. 

Cellulosics are easily coloured, suitable for dyeing by immersion in dye baths, and can be solvent polished, cut, cemented, drilled and decorated. Varnishing and serigraphy are easily used. 

The French Nuclear Research Center CEA announced the successful fabrication of high performances prototypes fuelled by H2 and based on thin films type structures on Si substrate obtained by micro-electronics fabrication techniques (RIE for fuel micro-channels, PVD for anode collector, CVD, serigraphy, inkjet for Pt catalyst, lithography) with a Nafion membrane [15]. An impressive power density of 300 mW cm with a stabilisation around 150 mW cm" during hundred hours was reported. 

Elaboration of thick films using serigraphy 7.2.4.I. Method description... 

The photographs in Figures 7.44, 7.45 and 7.46 - produced at low magnification (x 55) - show the influence of the composition on the morphology of the films treated at 900°C. In the case of the 50/50 ratio the link to the support is the worst of the three this is due to the fact that the two materials (glass and beta-alumina) have very different thermal coeflicients. We observe on these photographs the trace left by the serigraphy screen this trace appears because of viscosity phenomena which are a function of the eomposition.
