Direct Ni Electroless Metallization of Poly(etherimide) without Using Palladium as a Catalyst Mariène Charbonnier1,Yves Goepfert2,Maurice Romand1 (1.Laboratoire de Sciences et Ingenierie des... electroless metallization of polymers needs the grafting of a catalyst (palladium in the Pd(0) oxidation state) on the substrate surface to be coated. Our previous works on this topic [1-5] have......
Mechanical, electrical, and thermal expansion properties of carbon nanotube-based silver and silver–palladium alloy compositesHemant Pal1,2摘 要:The mechanical, electrical, and thermal expansion properties of carbon nanotube(CNT)-based silver and silver–palladium(10:1, w/w) alloy nanocomposites are reported. To tailor the properties of silver, CNTs were......
