optical vortex,conductive polymer

Optical vortex is a generic term for light waves with orbital angular momentum, and OV-LIFT, which is applied to laser-induced forward transfer, has attracted attention as a high-precision printing technology with stable linear flight of droplets.We have discovered the phenomenon of crystallization by printing with OV-LIFT, using as donor a conductive polymer that exhibits a golden luster due to lamellar microcrystals. The disadvantages of metallic coatings, such as low dispersion stability, mass, and cost, can be overcome. This result shows the effectiveness of OV-LIFT on conductive polymers and is expected to be put into practical use.
