Invention Summary

Laser ablation of polymeric materials results in more precise patterning and improved performance when the polymeric material decomposes into a gas capable of carrying ablation material away (carrier gas).

NDSU inventors have developed polymer films and additives that can be used in polymer films such as polyol photosensitizers carrier gas UV laser ablation sensitizers and other additives that can be used in preparation of such carrier films.
