Abstract: Oxygen scavenging polymeric compositions that possess an improved oxygen scavenging capability and can be formed into transparent/translucent thin films are disclosed. A composition can include iron powder, ferrous sulfate heptahydrate (FeSO4.7H2O) and glycerol dispersed in polyethylene. Such compositions are useful for creating packaging films with improved oxygen scavenging capability.

Abstract: A piezoelectric composite material is formed from a cellulosic material and an inorganic piezoelectric material dispersed in a piezoelectric polymer. The piezoelectric polymer of the composite material has a dielectric constant of from 10 or more. A method of making a piezoelectric is also disclosed wherein a matrix of a cellulosic material, an inorganic piezoelectric material, and a piezoelectric polymer material is formed. The matrix is formed into a piezoelectric composite body.

Abstract: A polymer composite thin film exhibiting piezoelectric properties may include a polymer matrix with base material of Polyoxymethylene (POM) and a piezoelectric additive of greater than approximately five (5) percent by weight of the polymer composite thin film. The piezoelectric additives may include BaTiO3 and KNN. The polymer composite thin film exhibits piezoelectric characteristics and may be used in electronic devices in piezoelectric actuators and piezoelectric sensors.
