  • Patent number: 10626329
    Abstract: A method of making a shape-programmable liquid crystal elastomer. The method includes preparing an alignment cell having a surface programmed with a plurality of domains. A cavity of the alignment cell is filled with a monomer solution. The monomers of the monomer solution are configured to align to the surface of the alignment cell. The aligned monomers are polymerized by Michael Addition. The polymerized monomers are then cross-linked to form a cross-linked liquid crystal elastomer. The cross-linking traps monomer alignment into a plurality of voxels with each voxel having a director orientation.

  • Patent number: 10590241
    Abstract: A family of new and novel molecules for mechanically superior two-dimensional (2D) polymers is described herein. By combining stiff carbon-containing cyclic polymer nodal units with more compliant linear polymer bridge units in an ordered, 2D repeating molecular structure it is possible to tailor the mechanical properties of 2D polymers and their assemblies to provide high stiffness, strength, and toughness. Furthermore, the inherent dimensionality of 2D polymers and their ability to be stacked into ordered and chemically interactive ensembles gives them inherent benefits in a variety of barrier and structural applications over current stiff and strong linear polymer technologies.

  • Publication number: 20140186312
    Abstract: The present inventions in various aspects provide elastic biodegradable polymers. In various embodiments, the polymers are formed by the reaction of a multifunctional alcohol or ether and a difunctional or higher order acid to form a pre-polymer, which is cross-linked to form the elastic biodegradable polymer. In preferred embodiments, the cross-linking is performed by functionalization of one or more OR groups on the pre-polymer backbone with vinyl, followed by photopolymerization to form the elastic biodegradable polymer composition or material. Preferably, acrylate is used to add one or more vinyls to the backbone of the pre-polymer to form an acrylated pre-polymer. In various embodiments, acrylated pre-polymers are co-polymerized with one or more acrylated co-polymers.

    Abstract: The present invention describes a method for repairing defects on a surface of an optical substrate. The method includes a step of providing a radiation curable coating and then applying the coating onto a surface of the optical substrate. The coating is then cured with a UV light source causing the refractive index of the coating to be less than ±10% of the refractive index of the substrate. The cured coating exhibits a viscosity less than about 315 CP at 25° C. The present invention also describes a novel coating composition for repairing optical substrates.
