Outline of Final Research Achievements

Organic palladium complexes were impregnated into nylon 6 fabric under supercritical carbon dioxide. The palladium ions were reduced thermally or through contacting with hydrogen, and then metal particles deposited in and on the fiber. Volume resistivity of the fabric decreased with increasing the amount of metallic palladium on the fiber, and it was 5.4 Ω･cm. The metal deposited layer was composited from the inside to the surface of fiber with uniform thickness of ca. 200 nm. The metal-composited fabric kept its resistivity on the order of 10 Ω･cm by 1000 times rubbing with cotton fabric through the JIS L 0849 II type rubbing tester.
