  • Publication number: 20150119238
    Abstract: A method for marking an item including a shape memory polymer (SMP) having a visual readable and/or machine readable graphic element on the surface of the item. The method includes pretreating the surface of the item; colouring the surface of the item with a dye solution containing an organic dye and an organic solvent; cleaning and drying the surface of the item; and engraving by at least partially ablating the surface of the item. The dyeing process is suitable for colouring the surface of a shape memory polymer (SMP), wherein the information is engraved in a form of a code or other label on the coloured surface. The colouring causes an increased contrast and thus facilitates machine readability of marking and coding without affecting the other properties of the SMP.

  • Publication number: 20150112002
    Abstract: The present invention relates to a method for improving polyimide (PI) non-adherence to substrate and a PI solution. The method includes the following steps: (1) providing a substrate and a PI solution, the PI solution comprising PI molecules and a solvent, the PI molecules having hydrophobic moieties; and (2) coating the PI solution on the substrate to form a PI film. The PI solution includes PI molecules and a solvent. The PI molecules have hydrophobic moieties. The solvent include N-methyl-2-pyrrolidone, ?-butyrolactone, butyl carbonate, or a mixture thereof. The PI molecules of the PI solution contain hydrophobic moieties and in coating the PI solution to a substrate, the hydrophobic moieties link with organic compounds on the substrate thereby enhancing affinity of the PI solution with surface of the substrate, improving the issue of PI non-adherence, and the heightening quality of printing the substrate.

  • Patent number: 9011309
    Abstract: An electromagnetic radiation activated device comprises a property changing material and at least one functionalized fullerene that upon irradiation of the functionalized fullerenes with electromagnetic radiation of one or more frequencies a thermally activated chemical or physical transformation occurs in the property changing material. The thermal activated transformation of the property changing material is triggered by the heating or combustion of the functionalized fullerenes upon their irradiation. The device can include a chemical agent that is embedded in the property changing material and is released when the material is heated by the functionalized fullerenes upon irradiation.
