  • Publication number: 20140255699
    Abstract: Provided are a resin blend, which includes a first resin, and a second resin having hydrogen-binding donor and acceptor, and having a difference in surface energy from the first resin at 25° C. of 0.1 to 35 mN/m, and is formed in a layer-separated structure, a pellet, a method of manufacturing the same, and a resin molded article having a specific layer-separated structure. Because of the resin blend, a molded article may have enhanced mechanical properties and surface hardness, and additional surface coating may be omitted, thereby reducing a processing time, increasing productivity, and reducing production costs.

  • Publication number: 20140255700
    Abstract: Provided are a resin blend including a first resin, and a second resin having a hydrophobic moiety represented by Formula 1 at a main chain and having a difference in surface energy from the first resin at 25° C. of 0.1 to 20 mN/m, and formed in a layer-separated structure, a pellet, a method of manufacturing the same, and a resin molded article having a specific layer-separated structure. Because of the resin blend, a molded product may have enhanced mechanical properties and surface hardness, and additional surface coating may be omitted, thereby reducing a processing time, increasing productivity, and reducing production costs.

  • Publication number: 20140089844
    Abstract: A mobile communication terminal including a display unit; a controller configured to display, on a screen of the display unit, a first list including a plurality of tasks; and an input unit configured to select at least one of the plurality of tasks. The controller is further configured to visually and discriminately divide the screen, display information corresponding to a task selected, display a second list including icons corresponding to tasks that are being currently executed, display progress state information indicating a progress state of the currently executing tasks on the bottom screen, and update the second list based on a detection result of the tasks being currently executed, and scroll through the icons listed in the second list so as to display other icons not being displayed in the bottom screen when a scroll signal indicating a scroll of the second list is received from the input unit.

  • Publication number: 20130323510
    Abstract: Provided is a resin blend including a first resin and a second resin, the second resin having a hydrophobic functional group in a side chain and having a surface energy difference of 0.1 to 20 mN/m from the first resin at 25° C., the resin blend being capable of forming a layer separation structure. Also, provided are a pellet, a method for preparing the same, and a resin molding articlemolding article having a specific layer separation structure. The resin blend may not only improve mechanical properties and surface hardness of the molding articlemolding article but also shorten process time, increase productivity and reduce production cost by omitting an additional surface coating step.
