Abstract: A kind of plastic is provided. With a total of 100 parts by weight, the plastic includes the following components in parts by weight: 25 to 90 parts of matrix resin; 1 to 60 parts of laser reflecting agent; and 0 to 70 parts of inorganic filler, where the inorganic filler is capable of being chemically corroded. When the matrix resin includes a resin component capable of being chemically corroded, parts by weight of the inorganic filler are greater than or equal to 0 parts; or when the matrix resin is fully a resin component incapable of being chemically corroded, parts by weight of the inorganic filler are greater than 0 parts. For the plastic, a low roughness surface can be obtained through chemical roughening, to form a desirable coating binding surface, and help implement metallization.

Abstract: The present disclosure relates to Wi-Fi link sleep and wake-up methods, electronic devices, and systems. In one example method, a first electronic device establishes a Wi-Fi direct link with a second electronic device. The first electronic device is a group owner (GO) of Wi-Fi Direct. The second electronic device is a group client (GC) of Wi-Fi Direct. The second electronic device may send a first request message to the first electronic device to trigger the first electronic device to enable Wi-Fi link sleep. When a wireless projection service is suspended, a Wi-Fi link used for wireless projection enters a low-power state in a timely manner. When the Wi-Fi direct link sleeps, the second electronic device may send a wake-up request message to the first electronic device to trigger the first electronic device to wake up the Wi-Fi link.
