    摘要: Disclosed is a microwave preparation method for producing polymeric nanoparticles in which a mixture is made that contains a monomer, an optional functionalize co-monomer, a polymerization initiator that is activated by microwave irradiation, a cross-linker that preferentially creates intra-particle cross-links during polymerization, and a water-based solvent which is then irradiated with microwave radiation to facilitate polymerization of the nanoparticles into sub-50 nm size range nanoparticles.

    摘要: An approach is presented for designing the polymeric recording layer for nanometer scale thermomechanical storage devices. Cross linked polymers are used as the recording layers in atomic force microscopy data storage devices, giving significantly improved performance when compared to the previously reported linear polymers. This results in superior wear resistance and enhanced erasing, critical features for the long-term multiple read-write cycles of such thermomechanical storage devices. In addition, this ability to introduce a predetermined extent of cross linking allows fine tuning of the thermal and force parameters in the R/W/E (read-write-erase) cycles.

    摘要: A process for producing bi-continuous morphologies in polymer melts and solids, wherein two distinct domains or phases percolate and macroscopically connect throughout the composition. The process proceeds by simply mixing the components in a common solvent and casting a film by slow removal of the solvent. Bulk materials can be produced by mixing the components in an extruder, compounder, or other specialized equipment for processing molten polymers, and forming into a pellet, fiber, film, sheet, or molded part. The invention allows the production of materials with unique or unusual combinations of transparency, high electronic or ionic conductivity, high vapor transport rates, and/or high absorption rates of moisture or vapors . Particles used in the present invention are 5-10 nm to yield a scale of the bi-continuous structures of 10-50 nm. The materials can be produced in bulk form, or in films 1-100 microns thick.
