Polymer Layered Silicate Nanocomposites : General Properties • At low layered silicate content (as low as 3 to 5 wt%) :• Improved material stiffness while maintaining good ultimate properties and impact strength• Improved high temperature stability• Enhanced/modified crystallinity (e.g., nylon-6)• Improved gas barrier properties (e.g., to oxygen and water vapor permeability)• Improved resistance against organic solvents• Enhanced flame retardant behavior (lower heat release, no longer dripping, charring)• Improved surface finish (gloss, smoothness)• Good optical properties (transparency, haziness,...)• Reduced linear thermal expansion• Improved processability and rheology,...
