Destruction of polymers under the action of laser radiation

Abstract: Laser ablation is one of the main mechanisms of polymers destruction under the action of laser radiation. In this paper, the basic information on laser ablation of polymers is presented. Under the action of laser radiation on the polymer, processes of thermal, thermo-oxidative, and mechanical degradation occur simultaneously, resulting in the evaporation of macromolecules fragments (up to oligomers), and in some cases, separation of polymer particles and filler by a gas or plasma jet is observed. In addition, … Show more

“…The laser ablation of the PDMS occurs through thermal, thermo-oxidative, and mechanical reactions, resulting in the evaporation of macromolecular fragments. , After these fragments are released, they come in contact with the substrate and settle on the surface, forming a thin coating of PDMS micro/nanoparticles. The farther the substrate from the laser-ablated PDMS, the lesser the fragments that reach the substrate due to the spreading of the vapor.…”
