Abstract
A fiber, film or foam includes a plasticizer and a charged claylinked gel (A). The charged claylinked gel (A) includes clay nanoparticles (C) which are crosslinked by a charged polymer (A′) such that any particular clay nanoparticle is linked to at least one other clay nanoparticle by the charged polymer (A′). Methods for producing the fibers, film and foam are also provided.
