A simple and efficient method is developed to create conductive copper thin films on polymer surfaces. Instead of regular palladium colloid inks, micropatterns of silver nitrate inks, which serve as an activating agent for copper plating, were printed and dried on flexible plastic substrates. The printed plastic sheets were then immersed in an electroless copper plating bath at 55 °C for 2 min to create copper thin films on the printed patterns. The prepared copper films have an electrical conductivity as high as 83% of bulk copper and show good adhesion on PET or PI substrates.
Vivica : My favorite character from childhood was Curious George. He wanted to learn about everyone and everything. I'm a lot like that, too. I think my own curiosity springs from my own curiosity springs from my early experiences with reading and writing. Here's where a teacher like my first grade teacher, Mrs. Jones, can make a big difference. If you teach children to read, write and spell and then inspire them to explore for themselves, you'll get kids with imagination and the power to think. And then like my man Curious George, they'll be ready to take on the world.
