Abstract
To establish the new technology named Roll-to-Roll Printed Electronics, it is needed to combine the roll to roll transportation system and coating technology effectively. For that purpose one of important factors to be considered is the effect of friction characteristics between the film and steel roller because plastic film used for high functional devices has been becoming thinner. In past research, however, as far as authors know, there is no research which describes friction characteristics between thin plastic film and steel roller. On the other hand, in our past research, it was found that friction coefficient was increased with decrease in film thickness. In this study, the static friction between the plastic film and steel roller was measured by pulley method while changing the roller surface roughness, web tension, and relative humidity. As a result, the static friction coefficient between thin film and steel roller was significantly influenced by roller surface roughness, web tension and relative humidity. It was confirmed statistically that contribution ratio of three factors, relative humidity, web tension and surface roughness are 23.8 %, 32.6 % and 36.1 %, were very high.
