Thermal expansion coefficient layered-silicate polymer

Over the last decade, the utility of layered silicate nanoparticles as additives to enhance polymer performance has been established (5-17). These nanoscale fillers result in physical behavior that is dramatically different from that observed for conventional microscale counterparts. For instance, increased modulus (7,8), decreased permeability (9-11), reduced coefficient of thermal expansion (CTE) (12,13) and impact strength retention (7,14) are observed with only a few volume percent addition of exfoliated layered silicate thus maintaining polymeric processability, cost and clarity.
