CHITOSAN FILMS WITH REDUCED SHRINKAGE AND LAMINATES MADE THEREFROM

Inclusion of a needle structured clay or the plate structured clay sodium montmorillonite in a chitosan film 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 clay can be used in make...

Zusammenfassung:	Inclusion of a needle structured clay or the plate structured clay sodium montmorillonite in a chitosan film 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 clay can be used in make a variety of finished articles that can be used to provide protection from hazardous chemical and biological agents.
