Abstract: An optically clear, high strength, high modulus, and high thermal conductivity polyethylene thin film may be formed from a crystallizable polymer and an additive configured to interact with the crystallizable polymer to facilitate crystallite alignment and, in some examples, create a higher crystalline content within the polyethylene thin film. The polyethylene thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 5% of the molecular weight of the crystallizable polymer. Example crystallizable polymers may include high molecular weight polyethylene, high density polyethylene, and ultra-high molecular weight polyethylene. Example additives may include low molecular weight polyethylene and polyethylene oligomers. The polyethylene thin film may be characterized by a Young's modulus of at least approximately 10 GPa, a tensile strength of at least approximately 0.7 GPa, and a thermal conductivity of at least approximately 5 W/mK.

Abstract: A mechanically and piezoelectrically anisotropic polymer article is formed from a crystallizable fluoropolymer and a nucleating agent. The polymer article may be a thin film or a fiber, for example. A crystalline phase may constitute at least approximately 50% of the polymer article. In certain examples, a fluoropolymer may include vinylidene fluoride, trifluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, and vinyl fluoride. The polymer article may include up to approximately 10 wt. % of the nucleating agent. Such a polymer article is optically transparent, has an elastic modulus of at least approximately 3 GPa, and an electromechanical coupling factor (k31) of at least approximately 0.15.

Abstract: A liquid dispersion includes a matrix phase of polymerizable material and at least 10% by volume of solid conductive particles distributed throughout the matrix. The conductive particles may have an average particle size of less than approximately 100 nm, and the liquid dispersion may have a viscosity of less than approximately 100 Poise. Such a liquid dispersion may be printed or extruded and then cured to form a solid thin film. The content and distribution of conductive particles within the thin film may reach a percolation threshold such that the thin film may form a conductive layer. Polymer-based devices, such as nanovoided polymer (NVP)-based actuators may be formed by co-extrusion of a nanovoided polymer material between conductive polymer electrodes.

Abstract: An optical film includes a block copolymer film defining a plurality of helically shaped cavities and a plurality of helically shaped organic solid crystals positioned within the plurality of helically shaped cavities. A method of making the optical film includes obtaining a film of a block copolymer solution including a chiral block copolymer and a non-chiral block copolymer on a substrate. The method includes annealing the film, thereby forming a plurality of helical structures from the chiral block copolymer defined within the non-chiral block copolymer and removing the plurality of helical structures, thereby creating a plurality of helically shaped cavities. The method further includes forming organic solid crystals inside the plurality of helically shaped cavities, thereby forming the optical film.

Abstract: A polymer multilayer includes two or more laminated layers of ultra-drawn, ultra-high molecular weight polyethylene or high density polyethylene. A transparent laminated structure may include such a polymer multilayer disposed between a pair of transparent substrates. The polymer multilayer may be configured to induce a compressive stress in a near surface region of each transparent substrate, which may improve the toughness and fracture resistance of the laminated structure. A photothermal dye may be incorporated into the polymer matrix and the compressive stresses may be achieved using photothermal actuation of the dye-containing polyethylene layers.
