摘要： Shape memory main-chain smectic-C elastomers are described, as are methods for their preparation and monomers used in such methods. The elastomers are prepared by hydrosilylation of a reaction mixture including a liquid crystalline diene, a crosslinking agent, and a bis(silyl hydride) compound. The elastomers exhibit shape-memory properties and spontaneously reversible shape changes. They are useful for fabrication of shape memory articles including, for example, implantable medical devices, contact lenses, reversible embossing media, and Fresnel lenses.

摘要： An amorphous, optically transparent, colorless shape memory assisted self-healing coating for optical glassware applications that uses a combination of surface shape memory and self-healing properties to repair damaged sites on glass substrates when exposed to a thermal stimulus. The coating includes a miscible combination of a network polymer and a linear polymer having glass transition temperate between room temperature and about 40 degrees C. The coating can be used for corrective eyewear, for windshields and windows in automobiles and motorcycles, as well for as optical coatings wherever needed.

摘要： A waterborne shape memory polymer coating that gives textiles and fibers good shape memory performance. An amphiphilic, crosslinkable grafted polysaccharide polymer was synthesized and provided in a water dispersion that can be applied to a flexible fibrous material and then crosslinked to yield good shape memory properties. The polymer coating showed good binding to human hair, which could be styled into a permanent shape (e.g., straight) during the crosslinked step. Next, this permanent shape can be styled to a temporary shape (e.g. curly) by heating and styling, and cooling. Finally, the permanent style can be regained by activation with water, heat, or both.

摘要： Shape memory polymers featuring reversible actuation capability under ambient stimulus for integration with apparel. One approach is to use a multiblock polymer consisting of two (or potentially more) blocks in which the one block is the crystalline switching block with relatively low melting transitions, the other block has a higher thermal transition, and the two blocks are linked together by a linker molecule. Another approach is to use a graft copolymer having high and low melting transitions where the graft copolymer has a first polymer serving as the backbone and a second polymer being grafted to or from the backbone at certain graft locations. A further approach is to use latent crosslinking of a semicrystalline polymer with reactive groups placed on the backbone.

摘要： A self-replenishing biocompatible hydrogel having a zwitterionic polymer embedded throughout the matrix system to act as a lubricant and a surface modified with the same zwitterionic polymer. When surface material loss occurs in the hydrogel, such as a surface crack or a scratch, the damage propagates through the matrix rupturing the pockets of lubricant. The zwitterionic polymer is then drawn into the site due to the change in entropy at the surface and the positive and negative charge groups of the side chains fuse across the damage cite due to strong electrostatic attraction causing inter-chain association.
