Investigation on replication of microstructures on flexible substrateds by roll embossing process

International audienceThe roll embossing is an efficient process to replicate micro-patterns at continuous polymeric films. This process has been selected for its capabilities for manufacturing by rapid fabrication concepts high quality micro-structures on polymeric thin films. The aim of this work is to develop experimental investigations and analyses of the proper embossing conditions (embossing velocity; material pressure and temperature) needed for the replication of microstructured parts with various geometries and sizes. In the present analysis, one propose a comparative that investigationconsidering filling rate, roughness and shape of embossed structures that have been realised and examined. The paper demonstrates that roll embossing shows proper replication facilities at the micro-scale, to reproduce same geometrical dimensions and surface roughness than these corresponding to the cavities
