After crosslinking the extruded material in the bath, the construct can subsequently be harvested from the nanoclay bath. The use of a thixotropic nanoclay support bath is concentration-dependent. Thixotropy is defined as a time-dependent shear thinning property, where application of external force reduces fluid viscosity and allow it to flow.

However, a higher degree of exfoliation can have a negative impact on impact strength as the internal stresses in the nanoclay structure increase [42]. Another proposed mechanism for fire retardancy in polymer/clay nanocomposites is the trapping of free radicals by paramagnetic iron entrapped in the clay, as demonstrated in polystyrene …
