Abstract
Inclusion of a needle structured sepiolite clay in a chitosan film in an amount of about 0.5 weight percent to about 8 weight percent was found to reduce shrinkage of the film. The clay is processed into a substantially dispersed form. Laminates fabricated from this chitosan film including dispersed sepiolite clay can be used in making a variety of finished articles that can be used to provide protection from hazardous chemical and biological agents.
