Figure 12.8. A photograph of a traditional roto-gravure label press that has a web width of 4 in. The press consists of a single gravure head that can be used to apply conductive inks, such as nanoparticle silver suspensions, onto surface-treated polymer substrates to generate patterned interconnects and electrodes.

Silver Nanoparticles. Silver nanoparticles have been found to have very good antibacterial action, and are being used to impregnate bandages they are also used to impregnate socks and added to underarm deodorants because the antibacterial action kills the bacteria responsible for the unpleasant smells.

Also investigating surface textiles electrodes, Pylatiuk et al. (2009) compared five different conductive materials three types of silicone rubbers loaded with carbon or other nanoparticles, silver-coated polyamide yams and a flexible thermoplastic elastomer loaded with silver-coated glass microspheres. The results of the test electrodes were compared with those of a standard Ag/AgCl gel electrode. It was found that the silicone mbbers and the coated polyamide yams gave results comparable to the reference gel electrodes. The nanoparticle-loaded silicone mbber gave very favourable results with the ability to be used dry and a signal to noise ratio better than the gel electrode reference.

In this experiment, silver(I) is reduced to silver metal but the particles remain small (< 50 mn diameter). Silver particle size is controlled by the solution pH, type of saccharide used and concentration of ammonia. Each of these parameters affects the redox potentials of the two half reactions shown in Equations 5 and 6, which in turn influence the reaction rate. Under the proper experimental conditions, many small silver metal clusters form rapidly. This is followed by slower growth of the clusters into nanoparticles. Silver metal atoms formed subsequently are distributed among the maity growing particles, creating many very small particles (42). Under other conditions, snch as those used to...
