| Popis: | A high volume printing process for polymer gratings at submicron scale was developed for cellulose acetate (CA) film. A flexible Ni-stamp, consisting printing pattern, was used as a master for patterning process. High speed roll-to-roll manufacturing method was tested using custom made roll-to-roll device. Device enables a high throughput and a low cost production method for micron and submicron structures. This small scale device is suitable for continuous imprinting using 50 mm wide plastic web. Roll-to-roll device consist an unwinder, an imprinting unit and a rewinder. We demonstrated continuous imprinting process using the 95 micron thick CA film as a substrate. Printing speeds from 0.2 m/min up to 20 m/min was used to demonstrate high volume process. Lifetime of the stamp was long and no structural change was observed after a several meters of imprints. The best replication is achieved at the speed of 0.2 m/min using pressure of 8 MPa and temperature of 105 °C. Height and quality of the printed gratings was characterized by AFM. |
