Summary:Characteristics of nonlinear optical limiting (limiting curves) of laser radiation in aqueous polymer systems with nanocarbon inclusions have been studied. Suspensions of nanotubes and soot stabilized by the amphiphilic polymer Pluronic F-127, the additives of which provide the system’s transition to a solid-like hydrogel aggregate state at room temperature, have been considered. The limiting materials after their optical breakdown by high-intensity radiation in the gel state have been regenerated using the thermoreversible hydrogel–isotropic solution phase transition. These systems are shown to be promising for self-healing optical materials.
