New Microlayer and Nanolayer Polymer Composites
Abstract
Created new microlayered and nanolayered polymer composites for various novel and unique applications, (1) Produced clear microlayered composites with improved ballistic performance (see attached, interim report 6/1/98 - 12/31/98). (2) Developed microlayered composites with highly anisotropic conductivity (see attached, interim report 6/1/98 - 12/31/98). (3) Polymer nanolayered systems of polypropylene were created having discoidal, meso-form morphologies. Also, high density polyethylene has been changed to a 'shesh-kabab' structure due to the fact that the nano-layer thickness is less than the radius of gyration of the polymer macromolecule (see attached, interim report (1/1/99 - 12/31/99). (4) High barrier, injection moldable systems have been produced by microlayering a polymer with good water barrier and a polymer with good oxygen barrier. Taking advantage of differences in melting points, layer integrity was maintained during injection molding in between the two melting points. This concept, which utilizes and maintains the large interfacial surface area achieved with microalyering, is broadly applicable to highly immiscible polymeric systems. (see attached, interim report 1/1/00 - 12/31/00). (5) One-dimensional photonic materials with applications to optical limiting and optical switching have been developed in conjunction with the Naval Research Laboratory. This was accomplished by synergistically combining nanolayer coextrusion methodology with dispersion of nonlinear dyes and careful control of nanolayer refractive indices. (see attached, interim report 1/1/00 - 12/31/00 and progress to date, 1/1/01 - 5/31/01).
