  • Photographic apparatus and manufacturing method thereof
    Patent number: 9497363
    Abstract: A photographic apparatus includes a photoelectric conversion element, an electrochromic element, and an image processor. The electrochromic element is disposed on a main path by which light travels to the photoelectric conversion element. The image processor is electrically connected to the electrochromic element for adjusting a transmittance of the electrochromic element.
    Type: Grant

  • Organic polyurethane shape memory material and a preparation method thereof
    Patent number: 8318889
    Abstract: An organic polyurethane shape memory material includes a C10 chain or C18 chain and consists of hard segment and soft segment. The material is produced by reacting the single-chain type dendrimer with diethylenetriamine to produce dendrimer. Then dendrimer reacts with N-(3-aminopropyl)diethanolamine to produce dendritic diols. Next, polymer HO(C6H10O2)xC2H4OC2H4(C6H10O2)yOH, where x+y=25˜26, reacts with methylenedi-p-phenyl diisocyanate, and at least one type of dendritic diols is added to produce the organic polyurethane shape memory material.

  • Organic polyurethane shape memory material and a preparation method thereof
    Publication number: 20090048418
    Abstract: An organic polyurethane shape memory material and a preparation method thereof are disclosed. The organic polyurethane shape memory material includes a C10 chain or C18 chain and it consists of hard segment and soft segment. The preparation method thereof includes the steps of: The single-chain type dendrimer reacts with diethylenetriamine to produce multiple chains type dendrimer. And then at least one type dendrimer reacts with N-(3-aminopropyl)diethanolamine to produce at least one type dendritic diols. Next polymer HO(C6H10O2)xC2H4OC2H4(C6H10O2)yOH, x+y=25˜26 reacts with methylenedi-p-phenyl diisocyanate and then at least one type dendritic diols is added to react so as to get organic polyurethane shape memory material. The material of the present invention overcomes shortcoming of metal alloy and ceramic such as poor processability, difficulty in modification and high cost. Moreover, it also increase mechanical properties of polymer.
