Adapters, terminal devices, USB connection devices and charging stations are disclosed. The adapter includes a first port configured to connect to an alternate current (AC) source, a conversion module configured to convert an AC power from the AC source into a direct current (DC) power, a second port configured to connect to a first electronic device and provide power thereto, an uplink interface configured to connect to the first electronic device, a downlink interface coupled with the conversion module to obtain an external power supply therefrom and configured to connect to a second electronic device, and a signal control module arranged between the uplink and downlink interfaces, and configured to control a status of a signal in the downlink interface based on a status of a power supply of the uplink interface. The second electronic device enters one of the operating and charging modes based on the status of the signal in the downlink interface, when the second electronic device is coupled with the downlink interface. With the present invention, charging of an electronic device which can be charged only upon recognizing the signal line status of the downlink interface can be enabled even if a computer is powered off or in a sleep state.

The invention provides a coating composition that provides high brightness, high gloss and superior print quality. The coated product comprises a substrate coated on at least one side with a coating composition comprising a pigment component and a binder component that is made of mixture of two binder resins. Both binder resins are capable of film forming. The first binder resin provides coating gloss and adhesion properties and the second binder resin enhances coating porosity, adhesion, and anti-static properties. The first binder resin that is used at 60-95% by weight of the total binder resin blend is selected from the group consisting of vinyl acetate acrylate, styrene acrylate and styrene butadiene acrylic copolymers. The second binder resin that is used at 5-40% by weight of the total binder resin blend is selected from the group consisting of anion type polystyrene derivatives, polyethylene glycol and polypropylene glycol.

A method of preparing a carbon nanotube/polymer composite material is provided. The method includes (a) providing a carbon nanotube-based film and a pre-polymer solution; (b) placing the carbon nanotube-based film at a bottom of a container, and pouring the pre-polymer solution in the container; and (c) polymerizing the pre-polymer solution and simultaneously integrating the pre-polymer solution with the carbon nanotube-based film. As such, a carbon nanotube/polymer composite material, including the polymer-impregnated nanotube layer and an upper polymer layer, is obtained. A multi-layer composite can be produced by essentially repeating this process, using the upper polymer layer as the base layer for the formation of the next layer set thereon.
