    Abstract: A structural three dimensional nanocomposite with improved mechanical properties is provided. The structural three dimensional nanocomposite includes (a) spherical shaped nanoparticles, (b) a matrix, and (c) an inter phase structure. The matrix may be selected from at least one of (a) polymer matrix, and (b) a nano metal matrix. The spherical shaped nanoparticles are reinforced with the matrix. The spherical shaped nanoparticles are uniformly distributed throughout the matrix. The inter phase structure transfers stress from the matrix to obtain the spherical shaped nanoparticles with improved mechanical properties. The structural three dimensional nanocomposite have high and equal mechanical strength in three dimensions when the structural three dimensional nanocomposite is at least one of (a) volume compressive stress condition, and (b) volume expansive stress condition.

    Abstract: An ink used for direct inkjet printing to plate based on nanometer material and a method for preparing same. Of the baseline total amount of the ink, 5 to 30 wt % is of film-forming resin, 0.01 to 5 wt % is of nanometer or micrometer dye, 30 to 60 wt % is of organic solvent, 0.01 to 5 wt % is of humectant, and water provides the balance; these ingredients are stirred and mixed at room temperature, and after the film-forming resin is completely dissolved, impurities and/or insoluble substances in the present invention are removed by means of multi-level filtering, and the obtained filtrate is the present ink. The ink in the present invention is sprayed on a metal base material surface by an inkjet printer o form a printing pattern which, after curing, can be directly printed on the machine, thus reducing chemical pollution and post-processing processes, while a press run of the printing plate can be up to 100,000 copies at a resolution of up to 175 lpi.
